Example calculations
Tap an example to prefill the calculator with sample values.
Search-led ecommerce
$25k revenue target at $85 AOV
A straightforward planning case for a store using paid search and a reasonable mid-funnel conversion rate.
Result: The budget lands in the low five figures only if conversion is healthy enough to support the CPC.
Meta offer test
$40k target with a $62 cart value
Useful when lower AOV forces you to win on cheaper clicks and a stronger conversion page.
Result: The channel can still work, but the impression volume climbs quickly when AOV stays modest.
How the ad budget estimate works
The calculator first converts the revenue goal into required orders using your average order value. It then works backward through click-to-order conversion rate to estimate the click volume you need.
Once click volume is known, CPC produces the spend requirement and CTR produces the top-of-funnel impression requirement. The result gives you a working budget target, not a guaranteed outcome.
Ad budget FAQs
Use these answers to frame AOV, conversion-rate, CPC, and CTR assumptions before you buy traffic.
Why does average order value matter so much?
Average order value determines how many conversions you need to reach the same revenue target. Lower AOV means more orders, more clicks, and usually more spend.
What conversion rate should I use?
Use the click-to-order conversion rate for the landing page or funnel you expect paid traffic to hit. If you are unsure, model a conservative case and an optimistic case before committing budget.
