Free calculator · For owners and agencies

How long until your ads tell you anything.

Six numbers. You get how long your budget takes to say which ad works, how many ads it can really compare, and whether Meta has enough to learn from. Agencies: run this with a client before the first ad. Free. No email needed. Your numbers stay in your browser.

We invented the examples. They aren't anyone's average. Put in yours. The link keeps them.

 

What this can't tell you

This tells you how long a reading takes. The reading still needs each visit that happened, tied to its ad.

We're building the part that can. How it will work. Leave your email and we'll write when it's ready.

How we worked this out

The arithmetic

Bookings are your money over the cost of one. Times how many happen. Split that across your ads and divide your number by it. That number is yours, not a rule.

How we checked it

This page runs each example below every time it loads, against the answer we did by hand.

What it leaves out

  • An even split. Meta rarely spends the same on every ad, so the slowest ad takes longer than this.
  • Luck. Ten is enough to see a big gap and not a small one.
  • Season. A slow month reads slow for every ad.
  • Meta's floor is its own figure: about 50 results per ad set in a week to leave learning. Most small accounts stay under it for bookings. They can still count what happened, and judge ads by hand.
