Frequently asked questions

What does this calculator solve?

It calculates how much room the current monthly economics leave for marketing after the entered overhead and owner-selected profit amount. That is an affordability ceiling under the inputs, not the budget the business should automatically spend next month.

Marketing Budget

Should the budget be a % of revenue or a fixed $?

Use the calculator result for the inputs entered and keep any market-response or operating recommendation separate from the deterministic calculation. Support that additional assumption with the business’s own evidence or an explicitly labelled scenario.

Marketing Budget

What inputs do I need?

Revenue, contribution margin, fixed overhead and the target profit (or the loss you can sustain while you ramp). No DB or platform — a calc is enough input to size the budget at a planning lens.

Marketing Budget

How often should I re-size?

Re-size when sales, contribution margin, fixed overhead or the profit amount to preserve changes materially. MarginKoala does not impose a universal monthly or weekly refresh cadence.
