Backoff calculator.

Plan a retry strategy: set the base delay, multiplier, retry count, and cap, and see the exact backoff schedule, the wait before each attempt, and the total time before giving up — so retries never outlast the deadline waiting on them.

Retries that help, not pile-ons

A naive retry loop — try again immediately, a fixed number of times — turns a brief hiccup into a self-inflicted outage, as every client hammers the struggling service in unison. Exponential backoff spaces the attempts out so the service gets room to recover, a cap keeps the waits sane, and jitter breaks up the synchronized waves. The number to watch is the total: retries that quietly add up to two minutes will blow past an upstream timeout and fail anyway.
