Cost of Quality calculator

Quality problems cost money twice: once when engineers stop work to fix an escaped bug, and again when an AI product gives a customer a wrong answer. Enter your own numbers to see what that adds up to each month. Nothing is stored, and the calculator estimates cost, not savings.

Escaped bugs

Bugs that got past testing and reached production.

Include engineering, QA and support time.

In your own currency.

Wrong AI answers

Your best estimate. Skip this if you have no AI features.

Support time, refunds or lost customers, in your own currency.

What this costs you

Enter your numbers to see the monthly cost. Fill in all the boxes in a group to include it.

These figures multiply the numbers you entered. They show what poor quality costs you today, not what testing would save. Nothing you type leaves this page.

Frequently asked questions

How is the cost calculated?

Escaped bugs: bugs per month, times hours to diagnose and fix each one, times the hourly cost of the people involved. Wrong AI answers: answers per month, times your estimated cost of each one. The total is the two added together, and the yearly figure is twelve times the monthly one.

Does this show what testing would save?

No. It shows what poor quality costs you today, based on your own estimates. How much of that cost testing removes depends on your product, so we scope it in a quote and don’t promise a figure.

Where do I find these numbers?

Your issue tracker shows escaped bugs and how long they took to fix. Support tickets, refunds and escalations show wrong AI answers and what they cost. Rough estimates are fine. Use the same method each month so you can compare.
