How do you forecast return on ad spend and profit?

Forecast ROAS by estimating clicks, conversion rate, and average order value from your budget, then dividing projected revenue by ad spend. Layer in gross margin to forecast real profit, and add repeat purchase behavior to project lifetime value for each monthly cohort. This turns a budget into a profit forecast before you spend a dollar.

In the worked example below, $40,000 in spend returns a 1.2x ROAS on first orders alone, and layering in repeat purchases shows how much of the true return revenue-only ROAS hides.

The formula

Worked example

Monthly budget
$40,000
Cost per click
$4
Conversion rate
4%
Avg order value
$120

About 10,000 clicks produce roughly 400 conversions at $120, or $48,000 in revenue on $40,000 spend, a 1.2x ROAS before lifetime value. Adding repeat purchases can lift the true return well above the first-order ROAS.

Frequently asked questions

What is a good ROAS for Google Ads?

Breakeven ROAS depends on your margin, so there is no single good number. Calculate the ROAS you need to break even from your profit per customer, then treat anything above it as profit and factor in lifetime value from repeat purchases.

How do you forecast ROAS before spending?

Estimate clicks from budget and cost per click, apply your conversion rate to project conversions, multiply by average order value for revenue, then divide revenue by spend. This gives a forecast ROAS you can pressure-test before committing budget.

Why include LTV in an ad forecast?

First-order ROAS ignores repeat purchases. Including lifetime value shows the true return on acquisition and often reveals room to spend more than first-order ROAS suggests.

How much budget do I need to forecast?

Any budget works. The forecaster scales clicks, conversions, revenue, and profit from the budget and unit economics you enter, so you can compare scenarios before deciding how much to spend.
