Marketing Budget Calculator
Start with what the business needs, then size the budget.
Budget = Target conversions × Target CPA × (1 + reserve)
How the Marketing Budget Calculator works
Free marketing budget calculator: work backwards from a conversion goal and target CPA to the budget needed, including a testing reserve.
You enter
- › Conversions needed
- › Target CPA
- › Testing reserve
- › Months
You get
- › Total budget
- › Monthly budget
- › Testing reserve amount
Worked example (default values): Conversions needed 500 · Target CPA $15 · Testing reserve 15% · Months 3 → Total budget $8,625 · Monthly budget $2,875 · Testing reserve amount $1,125.
