Ad Budget Calculator — free online

Before you run an ad campaign, the scary question is always money. How much do I need to spend to get the sales I want? Guessing burns cash fast. We added a free tool that does the math for you — Ad Budget & Reach Estimator — right in your browser.

What it does

You start from the end: the number of conversions you want. Then you fill in a few assumptions about your campaign — click-through rate, cost per click, and conversion rate. The tool works backwards and shows the budget and reach you need to get there, so you can plan with real numbers instead of a hunch.

Nothing leaves your device

Everything happens inside your browser. Your numbers and goals are never uploaded, never saved on a server, and never seen by anyone. Close the tab and there's nothing left behind.

How to use it

  1. Open Ad Budget & Reach Estimator and type in the number of conversions you're aiming for.
  2. Add your campaign assumptions: click-through rate, cost per click, and conversion rate.
  3. Read the budget and reach it gives you, and use those numbers to plan your campaign.

It's free with no limit. There are more small tools on the Apps page.
