A sales budget is the financial plan behind your revenue target. It sets out how much you expect to sell, what it will cost to make those sales, and what profit should remain. Without one, sales targets are wishes and marketing spend is guesswork. With one, every pound of sales activity can be judged against a number it was supposed to produce. This guide walks through how to create a sales budget step by step, with worked examples, a simple template structure you can copy, and practical advice drawn from how growing businesses actually do it.
First, a clarification that saves confusion: a sales budget is not the same as a marketing budget or a company budget. The marketing budget covers what you spend to generate demand. The sales budget covers the revenue you expect and the direct costs of achieving it, salaries, commission, travel, tools, and sales overheads. Together they tell you whether growth is profitable, not just whether it is happening.
Step 1: Set the revenue target from evidence, not optimism
Every sales budget starts with a revenue figure, and this is where most go wrong. Founders pick a round number that sounds good. Instead, build the target from three inputs: last year's actual revenue, your current pipeline, and your conversion data. If you closed £480,000 last year, your pipeline holds £300,000 of weighted opportunities, and you convert roughly 25% of qualified proposals, you have the raw material for a defensible target.
A practical method is the bottom-up build. Take each salesperson or sales channel, estimate their realistic capacity (meetings per week, proposals per month), multiply by your historic conversion rate and average deal value, and sum it up. Compare that against a top-down sanity check: what does the market support, and what did you actually achieve? If bottom-up says £600,000 and top-down says £900,000, the gap is your hiring, training, or lead-generation plan, and it needs to be explicit rather than hoped for.
Example: A Manchester B2B services firm with three salespeople, each running 8 qualified meetings a month, a 20% meeting-to-deal conversion rate, and a £6,000 average deal value: 3 × 8 × 12 × 20% × £6,000 = £691,200 annual revenue target. Every assumption is visible and therefore adjustable.
Step 2: Budget the cost of selling
Revenue without costs is fantasy. List every cost attached to the sales function. The big ones: base salaries, commission and bonuses, employer NICs and pensions, travel and entertaining, CRM and sales tooling subscriptions, training, and a share of overheads like office space. Commission deserves its own line and its own design thought: it should reward the behaviours in the budget, not just closed revenue. If the plan depends on new-logo acquisition, weight commission toward new business rather than renewals.
Example cost lines for the firm above might read: salaries £135,000; commission at target £45,000; NIC/pension £28,000; travel £12,000; CRM and tools £6,000; training £5,000; total cost of sales £231,000 against £691,200 revenue. That ratio, roughly 33%, becomes the number to watch. If the ratio drifts upward while revenue stalls, the budget is telling you the sales model needs attention, not more spending.
Step 3: Build the template and track monthly
A sales budget that lives in a spreadsheet nobody opens is decoration. Use a simple template with these columns: line item, annual budget, monthly budget (annual ÷ 12, adjusted for seasonality), actual, and variance. Break revenue down by month using your real seasonal pattern. Most UK B2B firms see December and August dip; most retailers see November and December spike. A flat twelfth-per-month budget guarantees false alarms.
A workable template structure:
Revenue section: new business revenue, existing client expansion, recurring/retained revenue, total revenue. Cost section: salaries, commission, benefits, travel, tools, training, allocated overheads, total cost of sales. Summary: gross contribution (revenue minus cost of sales), contribution margin %, cost per £1 of revenue. Review it monthly in a short meeting with one rule: variances get explanations and actions, not excuses. A 15% revenue shortfall in March is a problem to solve in April, not a footnote in December.
Expert advice: what experienced sales leaders do differently
First, they budget for ramp time. A new salesperson rarely produces in month one; allow three to six months depending on deal complexity, and do not count their full quota in the annual number. Second, they separate leading indicators from lagging ones. Revenue is lagging; meetings held, proposals sent, and pipeline coverage are leading. Budget targets for the leading metrics too, because those are the ones you can still fix mid-year.
Third, they keep a contingency. Markets shift, key deals slip, people leave. A 5–10% buffer on the cost side, or a stretch-vs-commit target structure, stops one bad quarter from breaking the plan. Fourth, they connect the sales budget to the CRM. If your pipeline data lives in spreadsheets, your budget is built on stale numbers. A properly set-up CRM gives you live conversion rates and pipeline values, which makes next year's budget dramatically easier. Our CRM development work often starts with exactly this problem: the data exists but nobody trusts it.
Finally, revisit the budget quarterly. An annual budget set in January and never touched is a museum piece. Markets, teams, and pricing change; a light quarterly reforecast keeps the budget honest without turning planning into a full-time job.
A sales budget is simply revenue targets plus the cost of achieving them, tracked monthly and adjusted quarterly. Build it bottom-up, cost it fully, template it simply, and review it honestly. If you want help connecting your sales data to your marketing so both budgets pull in the same direction, our digital marketing team works from numbers like these every day, and you can start the conversation here.

FAQs
What should be included in a sales budget?
Expected revenue broken down by source (new business, existing clients, recurring), and all sales costs: salaries, commission, benefits, travel, tools, training, and allocated overheads. The summary lines that matter most are total cost of sales and contribution margin.
How do I set a realistic sales target?
Build bottom-up from capacity, conversion rates, and average deal value, then sanity-check top-down against last year's actuals and market conditions. Targets built from your own historical data are far more reliable than aspirational round numbers.
What is a good sales budget template format?
Line items down the side; annual budget, monthly budget (seasonally adjusted), actual, and variance across the top. Keep revenue and costs in separate sections with a contribution summary at the bottom. Simple and reviewed monthly beats sophisticated and ignored.
How often should a sales budget be reviewed?
Monthly for variance review with the sales team, quarterly for a light reforecast. Investigate any variance over 10–15% promptly; small misses compound quietly into large ones.
What is the difference between a sales budget and a sales forecast?
The budget is the plan: what you intend to achieve and spend. The forecast is the prediction: what you now expect to achieve given current reality. The forecast should be updated regularly and compared against the budget; the gap between them is your management agenda.
