Exponential Backoff Calculator

Build a retry schedule from base delay, multiplier, maximum delay and retry count.

Total wait -
Last delay -
Retries -

Enter the example value or paste your own input, choose the mode when one is available, and read the first result card for the direct answer. The output area gives a copyable block for code reviews, documentation, API tests, classwork or troubleshooting notes.

What the result means

The schedule helps tune retry behavior for APIs and jobs without guessing total wait time.

What is not included

Jitter is not simulated. Production retry systems often add randomization to avoid synchronized retry spikes.

Privacy note

The calculation runs in your browser. Avoid pasting production secrets, credentials, private keys, customer data or regulated personal data unless your own policy allows browser-based tools.
