Target ROAS Calculator
Turn a Target ROAS percentage into the conversion value and approximate conversion volume required from a planned advertising budget. This is planning arithmetic, not a prediction of campaign performance.

Method & formula
Target ROAS is conversion value divided by advertising cost, expressed as a percentage. The calculator reverses that relationship to show the conversion value needed for your planned spend, then translates it into conversion volume using the average conversion value you enter.
- Target ROAS multiple = Target ROAS % / 100
- Required conversion value = planned ad spend * target ROAS multiple
- Required conversions = required conversion value / average conversion value
Example
A 500% Target ROAS on 10,000 of spend requires 50,000 of conversion value. At an average conversion value of 100, that corresponds to 500 conversions.

FAQ
Does this guarantee Google Ads will achieve the target?
No. It only translates your target into arithmetic thresholds. Actual delivery depends on auction conditions, conversion tracking, budget, bidding and other campaign factors.
Why show a whole-conversion threshold?
When conversions are discrete transactions, the exact mathematical count may be fractional. The whole-conversion figure rounds up to the first complete conversion count that meets or exceeds the value target.
