PPC Budget Calculator

PPC budget planning works backward from your conversion goals. Start with how many conversions you want, then calculate the traffic and budget needed to get there:

For example, if you want 100 conversions with a 3.75% conversion rate and a $2.00 CPC: you need 100 / 0.0375 = 2,667 clicks, and 2,667 x $2.00 = $5,334 in budget.

This gives you a baseline. Actual costs may vary based on competition, seasonality, and ad quality. Start with this estimate, then optimize based on real performance data.

PPC budget planning is the process of estimating how much you need to spend on pay-per-click advertising to achieve specific business goals. Rather than picking an arbitrary number, effective budget planning ties spend directly to expected outcomes.

The two biggest levers in your PPC budget are conversion rate and CPC. A small improvement in conversion rate dramatically reduces the budget needed. If your conversion rate doubles from 2% to 4%, your required budget drops by half for the same number of conversions.

Conversion rate is often more impactful than CPC. Many advertisers focus on reducing their cost per click, but improving what happens after the click — your landing page, offer, and creative — typically yields bigger budget savings. A 1% conversion rate improvement can save thousands per month.

When scaling PPC, budget does not scale linearly. Doubling your budget rarely doubles your conversions. As you exhaust your most relevant audience, incremental clicks become more expensive. Plan for diminishing returns and scale in increments of 20-30% to find your efficiency ceiling. For a systematic approach to scaling, read our Ad Creative Testing Guide.
