Every October, DTC founders sit down to write their revenue plan for the following year. Most start in the same place: last year's revenue, a growth percentage layered on top, and a rough sense that if they can just hold their ROAS while spending more, the target becomes achievable. By March, most of those plans are already broken. Not because the founder was incompetent. Because the plan was built on a number that was never reliable.
ROAS is a marketing efficiency metric. It tells you how much revenue a channel generated per pound spent on it. It does not tell you whether that revenue was profitable, whether it can be replicated at higher spend, or whether the attribution model it was based on reflects actual cash flowing through the business. Platforms inflate ROAS through view-through attribution and assisted conversion windows. Meta campaigns that reported 4.2x ROAS in November routinely restate to 2.8x when cross-referenced against post-purchase survey data. You cannot plan a year on a number that shifts 30% depending on how you look at it.
The correct starting point is contribution margin. Not ROAS, not gross margin, not revenue. Contribution margin per order is the only number that tells you whether each unit you sell generates the headroom to cover your fixed costs and, eventually, produce profit. Build your 2027 plan from that number, and the revenue target becomes a consequence of the model. Build it from a revenue target first, and the model becomes a rationalisation of a number you already decided you wanted.
Why your 2026 ROAS is not a planning assumption for 2027
Paid media ROAS degrades as budgets scale. This is not a theory. It is a documented property of how Meta, Google, and TikTok auction systems work. When you double your daily budget on a campaign that was running efficiently at £200 a day, the algorithm has to bid into a larger audience pool that was previously excluded because it was less likely to convert. The marginal user acquired at £400 a day costs more and converts less than the marginal user acquired at £200 a day. ROAS falls. This is not a creative problem or an account structure problem. It is arithmetic.
The scale at which this degradation becomes significant varies by brand and category, but a useful rule of thumb is that most DTC brands see meaningful ROAS compression when paid media spend moves above 3-4% of total addressable audience size. For a niche wellness brand targeting a UK audience of 600,000 people, that inflection point may come at £8,000-£12,000 per month. For a beauty brand with a broader audience, it may not appear until £40,000 per month. Either way, assuming 2026's ROAS holds at higher spend is almost always wrong.
There is a second problem: attribution drift. Post-iOS 14 attribution in Meta is modelled, not measured. The platform estimates conversions it cannot directly observe using statistical inference. That inference can be significantly more generous during high-intent periods like BFCM, when user purchase intent is elevated across the board and the model assigns more credit to touchpoints that happened to appear before a conversion regardless of whether they caused it. Running your 2027 planning assumptions from November 2026 campaign data is likely to produce a plan built on the most inflated ROAS data of the year.
The six budget lines every DTC brand needs before January
A DTC budget that works has six lines. Not fifteen. Not two. Six categories that account for every pound that flows through the business. If any one of these is missing from your plan, you have a spreadsheet that will feel accurate for six weeks and then cause a cash crisis.
Cost of goods and landed cost per unit
This is your product cost including manufacturing, inbound freight, import duties, and any quality control or inspection fees. Express it per unit, not in total, and calculate it forward using your projected order volumes. If you are importing from Asia and your production lead time is 12 weeks, any stock you need in March must be ordered in December. The cash for that stock needs to exist in November, before your BFCM revenue has cleared.
Budget line: COGS as a percentage of revenue, compared to your current blended contribution margin. If your 2027 plan requires COGS to improve (through supplier renegotiation, higher volume commitments, or product reformulation), model the current COGS rate as the conservative case and the improved rate as the base case. Do not plan on the improved rate until the renegotiation is complete and signed.
Variable fulfilment and outbound shipping per order
Your 3PL or in-house fulfilment cost per order, including pick, pack, outbound shipping, and all variable overages. Calculate this as a per-order cost and apply it to your projected order count, not to revenue. Fulfilment costs scale with orders, not with revenue, which means increasing AOV improves your blended fulfilment ratio without adding any cost. If your plan includes an AOV improvement strategy (bundles, thresholds, free gift mechanics), model the fulfilment ratio at current AOV for the conservative case.
One thing most founders underestimate in fulfilment budgeting: peak surcharges. Most UK 3PLs apply November-January surcharges that add 8-15% to their standard rates during the period your order volume is highest. If you are modelling 2027 fulfilment costs from your off-peak invoice data, your Q4 2027 actuals will be worse than planned.
Paid media spend by channel
Break this out by channel, not as a blended total. Meta, Google, TikTok, and any other paid acquisition channel should each have their own spend line and their own efficiency target (MER or ROAS, consistently defined). This matters because channels have different degradation curves, different seasonality profiles, and different minimum viable budget levels to run efficiently. A channel that performs at £5,000 per month may not perform proportionally well at £2,500 per month if the algorithm requires a minimum data volume to optimise.
Set your paid media budget from a target MER, not from a spend level. If your contribution margin is 45%, your minimum breakeven MER for paid media is 2.2x (1 divided by 0.45). A realistic profitable MER target, accounting for fixed cost coverage, is 3.0-3.5x. Work backwards: if you need £50,000 of attributed revenue from paid media at a 3x MER, your budget is £16,700. That is a budget built from economics, not from last year's spend.
Retention and owned channel costs
Klaviyo, SMS platform, loyalty programme, and any tool that costs money regardless of whether it generates revenue in a given month. Email and SMS are often treated as near-zero cost channels, which is correct on a marginal basis, but the platform fees are real fixed costs that need to be in the budget. At £100,000 monthly revenue, Klaviyo alone may cost £800-£1,200 per month depending on list size and message volume.
More importantly: budget your retention investment at the front of the plan, not as the thing you add when paid media is performing. The brands that survive Q1 downturns do so because their repeat purchase rate is high enough to generate revenue without requiring paid acquisition. If email drives 35% of revenue in October, it will be 45-50% of revenue in January. Building the email and SMS programme in Q4 to extract revenue from BFCM buyers before they go cold is the most important retention investment you can make for 2027.
Fixed operating overhead
Staff salaries, contracted services, office or studio costs, technology subscriptions, and any cost that does not change when your order volume changes. This is the floor your contribution margin has to cover before any profit is possible. Calculate your current monthly fixed overhead and project it forward with any planned hiring or infrastructure changes. Then divide it by your contribution margin percentage to calculate the minimum revenue required each month just to cover operating costs. That number is your breakeven revenue. It belongs at the top of every monthly review.
A brand with £25,000 per month in fixed overhead and a 42% contribution margin needs £59,524 of monthly revenue to cover fixed costs alone, before any profit. Below that number, the business is consuming cash. Knowing that figure, and tracking actuals against it every month, is the single most important shift most founder-led brands can make in how they manage their business.
Working capital reserve for inventory
This is the line most founders omit and most plans fail because of. If you are growing, you need to buy more stock before you sell it. If your inventory turn is four times per year (a 12-week cycle, common for imported CPG products), and you plan to grow revenue 40% in 2027, you need to fund 40% more inventory. If your average stock investment is £30,000, a 40% growth target requires an additional £12,000 in inventory spend before you generate any additional revenue.
The Q1 trap happens when BFCM has consumed your stock, you need to reorder in December or January, and your January revenue is 35% below November. The cash to fund Q1 inventory must come from Q4 profit, not from Q4 revenue. If BFCM is breaking even on contribution margin (because you are running deep discounts), there is no Q4 profit to fund Q1 stock. Model your working capital requirements quarterly and ensure the cash to fund each quarter's inventory commitment exists at the start of that quarter, not partway through it.
How to work backwards from your profit target
Once you have the six lines built, the planning exercise works backwards from a net profit or owner's salary target, not forward from a revenue aspiration. Here is the sequence.
Set your net cash target
What do you need the business to produce in 2027 to justify the risk and effort? This is either a profit number (if the business is your primary income), a salary number (if you pay yourself from the business and want a specific level of personal income), or a reinvestment number (if you are deliberately running at breakeven to fund growth). Be specific. 'I want to grow' is not a financial target. 'I want to draw £60,000 salary and retain £20,000 for inventory investment' is a financial target.
Calculate required gross contribution
Add your target net cash to your projected fixed overhead costs (all of budget line 5). The result is the gross contribution your variable operations need to produce. If you need £80,000 net (salary plus retained profit) and your fixed overhead is £240,000 annually (£20,000 per month), you need £320,000 of gross contribution across 2027.
Back-calculate revenue from contribution margin
Divide your required gross contribution by your current contribution margin percentage. If you need £320,000 of gross contribution and your contribution margin is 42%, you need £762,000 of revenue. That is your minimum viable revenue target for 2027. If that number is achievable based on current trajectory and planned investment, proceed. If it requires growth you cannot credibly fund, the target needs to change or the cost base needs to shrink.
Allocate revenue to channels
Break the revenue target into the channels that will deliver it. If email and owned channels drove 30% of 2026 revenue without paid media cost, that 30% is almost free to replicate. The remaining 70% needs to come from paid acquisition, SEO, or referral. Calculate the paid media budget implied by that acquisition requirement at your target MER. If the implied paid media budget exceeds what you can fund from working capital, either the revenue target is too high, the channel mix needs to change, or you need an external capital source.
Check inventory implications
Take your quarterly revenue plan and translate it into unit volumes by SKU. Multiply by your COGS per unit to get your quarterly stock purchase requirement. Map that against your cash position at the start of each quarter. Wherever the required stock investment exceeds available cash, you have identified a funding gap. That gap needs to be addressed in the plan through inventory financing, a credit facility, or adjusted sales targets, not discovered in March when the stock order is due and the cash is not there.
Model three scenarios, not one plan
Every plan has a base case. Most plans only have a base case. That is the problem. The value of scenario modelling is not choosing which scenario will happen. It is knowing in advance what you will do operationally when you are clearly tracking the conservative case by end of Q1, rather than discovering in April that you are six weeks behind plan and now need to make reactive decisions under pressure.
No improvement in channel efficiency from 2026 levels. Revenue grows at the organic rate implied by list growth, repeat purchase rate, and any existing channel investment. This scenario does not assume any new channels, major creative improvements, or campaign optimisation. If your business cannot sustain itself in this scenario, your cost base is already too large for your current revenue trajectory. Conservative is not a pessimistic scenario. It is the financially honest baseline.
Planned paid media investment achieves target MER. Email and SMS programmes deliver at current attributed revenue share. Any new channels (Google, TikTok Shop, wholesale) deliver at the conservative end of comparable brand benchmarks. New product launches convert at 60-70% of existing hero SKU performance. This is the scenario you plan against operationally, but it requires all your planned investments to perform as expected simultaneously. Most years, one thing underperforms. The base case is a target, not a forecast.
Channel efficiency improves 20-30% through creative iteration, audience expansion, or reduced CPMs. A new channel significantly outperforms benchmarks. A wholesale partnership or major stockist adds a channel of revenue outside your modelled plan. Contribution margin improves through a supplier renegotiation or price increase that does not materially damage conversion. This scenario is not planned for, but it is useful to model because it tells you what your inventory and fulfilment constraints look like if everything works. Growing faster than your 3PL can handle, or running out of stock in the middle of a breakthrough month, is a real operational risk.
The quarterly review rhythm that keeps the plan honest
A plan reviewed once a year is a document. A plan reviewed every 13 weeks is a management tool. Four metrics, measured against the model at the end of each quarter, will tell you whether you are on track before it is too late to adjust.
The first is contribution margin per order versus the model assumption. If contribution margin has drifted more than three percentage points in either direction from your plan, something in your variable cost structure has changed: supplier pricing, fulfilment contract, return rate, or channel mix shift towards lower-margin products. Find it before it compounds across three more months.
The second is CAC payback period by channel, measured against the target in your plan. If the time to recover customer acquisition cost has extended beyond 60 days on a channel you modelled at 30-45 days, either the channel is degrading at your current spend level or your attribution model is overstating efficiency. Both need to be addressed before you scale spend further.
The third is repeat purchase rate at 90 days. This is the leading indicator of email programme health and LTV. If your 90-day repeat purchase rate is falling quarter on quarter, your email and post-purchase experience is not doing its job. A 1-point drop in 90-day repeat rate at 10,000 customers per quarter represents approximately 100 fewer repeat orders. At a £35 average order value, that is £3,500 of revenue per quarter you planned for and are not receiving. At scale, that compound effect is the difference between a plan that tracks and one that falls silently short month after month.
The fourth is cash runway in weeks. At the end of each quarter, divide your current cash balance by your average weekly operating outflow (fixed costs plus stock purchases plus media spend). The result is how many weeks your business can operate at the current run rate without any incoming revenue. Below 12 weeks, you need to act. Below 8 weeks, you are already in a crisis. Below 4 weeks, your options are severely constrained. Most founders who describe their business as "fine" in the month before a cash crisis had a cash runway that had been declining for two quarters, and they were not tracking it.
What this looks like in practice
A wellness supplements brand came into a planning audit in October 2025 with a slide showing 3.8x blended ROAS from the previous six months, a revenue target of £1.4M for 2026 (up from £900K in 2025), and a plan that amounted to "spend more on Meta."
When we pulled the actual contribution margin, it was 38%, not the 52% gross margin figure they had been using. The 3.8x ROAS included a heavy BFCM period running 30% discount promotions; normalised off-peak ROAS on the same campaigns was 2.6x. At 38% contribution margin, a 2.6x MER means they were generating 38p of contribution per £1 of revenue, of which the paid media itself consumed 38p (1 divided by 2.6). Breakeven on media, before any fixed cost. Every pound they "profited" on paid media was immediately required to cover overheads.
The revenue plan required £490,000 of paid media spend to hit £1.4M at their assumed ROAS. Their working capital could fund approximately £280,000 of paid media before they needed to reinvest BFCM revenue. The plan was only achievable if BFCM generated enough profit to fund Q1 and Q2 media. At a 30% discount in BFCM and a 38% contribution margin, the BFCM margin was approximately 8%. There was no Q1 profit to reinvest.
The revised plan was built from a £62,000 salary target (the founder's actual requirement), a £22,000 fixed overhead monthly run rate, and a contribution margin improvement from 38% to 44% through a supplier renegotiation and £2 price increase. The resulting minimum viable revenue was £962,000, not £1.4M. The paid media budget implied by that target at a 3x MER was £180,000 for the year. Achievable. Fundable. Profitable. The £1.4M plan was not.

Frequently asked questions
How should a DTC brand set its revenue target for 2027?
Start with contribution margin, not last year's ROAS. Decide how much net profit or free cash flow you need to sustain operations, then work backwards through fixed costs, variable costs, and required marketing efficiency to arrive at the revenue needed. A revenue target built from margin requirements is realistic. A revenue target built from ambition alone usually destroys margin in Q2 when the plan is not tracking and founders panic-spend on ads.
What are the six budget lines every DTC brand needs in their 2027 plan?
The six non-negotiable lines are: (1) Cost of goods and landed cost per unit, (2) Variable fulfilment and shipping per order, (3) Paid media and acquisition spend by channel, (4) Retention and owned channel costs including email, SMS, and loyalty, (5) Fixed operating overhead including staff, tech, and rent, and (6) Working capital reserve for inventory pre-financing. Missing any one of these produces a plan that looks profitable on paper and destroys cash in practice.
Why do DTC brands run out of cash even when revenue is growing?
Because inventory has to be paid for before it is sold. A brand growing 30% year-on-year needs to buy 30% more stock each cycle, often 60-90 days before that stock converts to revenue. If contribution margin is thin and the working capital cycle is not funded, growth itself becomes the cash drain. This is the Q1 trap: BFCM drives record revenue in November and December, brands reinvest that cash into Q1 stock, then January revenue drops 30-40% and the cash position collapses.
What is a realistic DTC ad spend budget as a percentage of revenue?
For a DTC brand with a 40-50% contribution margin targeting profitable growth, paid media should sit at 10-20% of revenue, producing a Marketing Efficiency Ratio of 3-5x on that spend. Brands spending more than 25% of revenue on paid media with a sub-50% contribution margin are almost always buying revenue rather than profit. The correct figure varies by LTV: brands with strong repeat purchase rates can justify higher first-order acquisition costs because the second and third purchase carry no marginal acquisition cost.
Should I plan for three scenarios or just one target?
Always model three scenarios: conservative, base, and growth. The value is not picking the right scenario. The value is knowing in advance which financial ratios change in each scenario and what you will do operationally when you are tracking conservative versus growth by end of Q1. Most founders who do not model scenarios make reactive decisions in March that cost them the rest of the year.
What should DTC brands review each quarter to stay on their annual plan?
Four metrics reviewed against plan: contribution margin per order versus the model assumption; CAC payback period by channel against target; repeat purchase rate at 90 days as the leading indicator of email health and LTV; and cash runway in weeks. Of these, cash runway is the most important and the most commonly ignored. Below 12 weeks of runway, you need to act. Most brands that describe a cash crisis as sudden had runway declining for two quarters before it became visible.
