Marketing Budget Calculator: Set a Budget and Test Its Implications
Start with your numbers.
The default percentage and allocation are illustrative, not recommended benchmarks. Use your business's goals, margins, cash constraints and delivery resources to choose appropriate inputs. The calculator runs locally and does not submit or store your values.
This interactive calculator requires JavaScript. The formulas and worked example below remain available.
How to use it
- Enter annual revenue or a clearly labelled annual planning estimate.
- Enter the percentage you want to model as a marketing budget.
- Allocate 100% across paid media; content and SEO; lifecycle and CRM; and creative, tools and operations.
- Optionally enter an annual new-customer goal and a target marketing-only cost per new customer for a second planning view.
The categories are a starting framework. Assign each cost once. People, fees and production need to be represented in the relevant category if they belong in your marketing envelope. Sales costs are separate from this model.
The formulas
Annual budget = annual revenue × marketing percentage.
Monthly planning average = annual budget ÷ 12.
Category budget = annual budget × category allocation.
Goal-implied marketing investment = new-customer goal × target marketing cost per new customer.
The allocation must total 100%. The goal calculation is a second planning check, not an additional amount automatically added to the percentage-based budget. Comparing them identifies a difference in assumptions; it does not prove feasibility.
Worked example
An annual revenue assumption of $1,000,000 at an 8% marketing share produces an $80,000 annual budget, or a $6,666.67 monthly planning average. Allocations of 40%, 30%, 20% and 10% give $32,000, $24,000, $16,000 and $8,000 respectively.
A goal of 100 new customers at an assumed $800 marketing cost per customer also implies $80,000. That alignment is arithmetic. It does not show that channels can acquire those customers at that cost or that sales can serve them.
Monthly averages do not prescribe a flat spend schedule. Launches, seasonal demand and production timing may need a different allocation across the year.
A revenue percentage is not a strategy
The business still needs to decide the objective, route to demand and cost of execution. A business entering a new market may need a different program from one improving retention. A revenue percentage can also be unhelpful when current revenue is small but the launch requires a substantial fixed investment.
Use marketing strategy to connect those choices. Marketing benchmarks show why spending ratios need comparable cohorts rather than becoming universal rules.
Compare the envelope with the funnel
If the goal-implied investment exceeds the percentage envelope, examine the customer target, acquisition assumption or funding constraint. If it is lower, do not assume the remainder is unnecessary: the envelope may also fund longer-term content, retention or operating work.
The CAC calculator includes sales and marketing costs. This calculator's optional goal check uses marketing-only cost, so entering fully loaded CAC would mix the cost bases. The lead generation calculator can help explore campaign-stage assumptions.
Budget calculator questions
What percentage should a business spend?
There is no universal answer. Choose a planning range from your economics and objective, then assess the work needed to make it useful.
Should sales payroll be included?
It belongs in a wider sales-and-marketing model. This tool calculates a marketing envelope and labels its customer-cost assumption accordingly.
Can the calculator recommend channel percentages?
No. The initial allocations are examples. Your audience, bottleneck, measurement and resources determine a defensible mix.
