Marketing Budget Calculator
How much should you spend on marketing? Enter your revenue, industry, and growth goal to get a defensible budget range — with a margin check so you don't over-commit. No more setting budget by gut feeling or last year's number plus 10%.
Total revenue for the chosen period.
Each industry has different benchmarks for what's sustainable.
Adjusts the recommended budget within your industry range.
Used to verify the budget is sustainable for your margin.
Industry ranges are approximate, drawn from public benchmarks (CMO Survey, Gartner, Statista). The recommended budget is a planning starting point, not a guarantee. Your actual optimal spend depends on competitive dynamics, channel mix, and your CAC payback period.
Most marketing budgets are inherited, not designed
The most common way SMBs set their marketing budget is "what we spent last year, plus or minus." The second most common is "what the agency we hired suggested." The third is "a round number that felt right at the time."
None of these are budgets. They are inherited numbers. A real marketing budget is the output of three inputs: how big the business is, what's typical for the category you operate in, and what your margin can sustain after overhead.
Set the percentage of revenue first, then convert to a monthly number for execution. If you set the monthly number first and let it drift, your budget shrinks as a share of revenue every year you grow — and you under-invest in the growth that's working.
If the recommended budget for your industry would consume more than 50% of your gross profit, the issue isn't the budget — it's the margin. Either your pricing is too low, your COGS is too high, or your business model can't sustain category-typical marketing investment. That's a different conversation, and it's the one the Digital Economic Review is built for.

Marketing budget FAQ
There is no single right answer. The defensible range depends on three things: your industry (which sets benchmark norms), your growth goal (defending share vs aggressive growth), and your margin structure (which decides what your business can sustain). For most established SMBs, marketing sits between 5% and 15% of revenue. For growth-stage SaaS, 20-40% is normal. The calculator above runs the math against your actual inputs.
Approximate ranges from public benchmarks: B2B services 6-12%, B2B SaaS 15-30% mature / 30-50% growth, e-commerce 8-22%, consumer goods 10-15%, professional services 4-10%, local services 3-10%. The wider the range within an industry, the more your specific economics matter — a high-margin DTC brand can sustain 22%; a thin-margin one can't run more than 10% without losing money.
Use percentage of revenue as the planning baseline, then convert to a fixed monthly budget for execution. Percentage gives you a sustainable framework that scales with the business; fixed budget gives the team a number to work against. The error most businesses make is setting a fixed budget that drifts down as a percentage of revenue over time, which silently under-invests in growth.
Pick the closest analog. The bigger principle: marketing budget should sit somewhere between 'enough to maintain visibility in your category' and 'as much as your gross margin can sustain after overhead.' If you're in a niche where competitors don't advertise, your budget can be lower. If you're in a category where customer attention is contested (e-commerce, education, SaaS), it has to be higher.
No. This calculator is for marketing budget specifically: ad spend, tools, content production, marketing team or agency fees. Sales costs (sales reps, sales tooling, commissions) are usually budgeted separately because they convert demand rather than create it. For B2B businesses where marketing and sales blend (BDR-driven outbound, for example), the relevant view is total CAC across both functions, not just marketing budget.
Industry-benchmark marketing budgets assume average margin structure. If your margin is significantly below average, the same percentage of revenue consumes a much larger share of your gross profit, leaving less for overhead, salaries, and net profit. The margin check on the calculator flags when the recommended budget would consume more than 50-70% of your gross profit — the point where the model becomes structurally unsustainable.
