Webhook Retry Schedule Calculator

Plan webhook retry backoff before you ship

SaaS platforms retry failed webhook deliveries with exponential backoff, jitter, and a maximum delay cap. Guessing those numbers in a spreadsheet is error-prone. This calculator models each retry attempt using your base delay, multiplier, jitter percentage, and cap so you can see per-attempt waits and total time before the queue gives up.

How the schedule is computed

1. Attempt 1 waits the initial delay (often 1–5 seconds).
2. Each later attempt multiplies the previous base delay by your backoff factor (commonly 2×).
3. Delays never exceed the max delay you set (for example 60 seconds).
4. Jitter shows a min/max band at ± the percent you enter; production systems pick a random value inside that band to avoid thundering herds.
