A plan based on your assumptions. Actual campaign results can differ.
How it works
Conversions × expected CPA gives the base budget. Revenue goals are divided by average conversion value. Contingency is added, then divided by campaign days.
Know the limits
These are user-defined planning scenarios, not predictions, guarantees, platform pacing limits or advice that an increase is safe. No paid API or account connection.

Work backwards from your campaign goal
You have a sales or lead target but no clear spending plan. This ad budget calculator works backwards from a goal using your expected acquisition costs. It is useful for a campaign brief, a monthly planning discussion or checking whether a target is financially plausible. It does not choose a budget from industry averages: the quality of the plan depends on the assumptions you supply.
How to use Campaign Budget Calculator
Choose a conversion goal or revenue goal. For revenue, enter the average value of one conversion so the calculator can estimate the required volume.
Choose an expected CPA or use CPC plus click-to-conversion rate. Use figures from a comparable campaign, and enter the campaign duration in whole days.
Add a contingency percentage if you want a reserve, then calculate. Review the base budget, reserve and simple daily planning average separately.
What do the results mean?
The base budget funds the expected conversion requirement at your assumed acquisition cost. Contingency is extra spending room, not a promise of extra conversions. A revenue target can imply a fractional expected conversion count. The daily figure is an allocation average, not an advertising platform’s billing or pacing limit.
What to do next
Test the proposed spend in Campaign Forecast Calculator, including less favorable assumptions, before treating the budget as a committed target.

Common questions about Campaign Budget Calculator
Can I calculate a budget without historical CPA?
You can use CPC and a plausible click-to-conversion rate instead. Label the result as a scenario and revise it when actual campaign evidence becomes available.
Does a 10% contingency mean 10% more sales?
No. It is a budget reserve. The tool does not assume that using the reserve produces results at an unchanged cost or that the campaign will spend the full amount.
