Ad Spend forecaster.

Estimate the budget required to hit your future revenue targets based on current performance.

Future Revenue Goal ($) Current ROAS (x)

Estimated Ad Budget Required

$28,571.43

To hit $100,000 in revenue at your current efficiency, you need to spend approximately $28,571.429.

How This Forecast Works

This calculator backs into the ad budget needed to hit a future revenue goal, using whichever efficiency metric you already track.

Required Spend = Revenue Target / ROAS

Or, if you think in cost-per-acquisition terms instead:

Required Spend = (Revenue Target / AOV) x CPA

A note on accuracy:

This is a linear projection based on your current efficiency holding steady. In reality, ROAS and CPA usually get worse as you scale spend into a smaller pool of high-intent inventory — treat this number as a floor, not a guarantee.

Frequently Asked Questions

Divide your revenue target by your expected efficiency. If you're forecasting by ROAS, the formula is Required Spend = Revenue Target / ROAS. If you're forecasting by CPA, it's Required Spend = (Revenue Target / Average Order Value) x CPA. Both approaches back into the same answer from different inputs.
