Transaction Timeout Risk Calculator

Enter RTT, jitter, packet loss, and transaction type to estimate total transaction duration and compare it against your configured timeout. Calculates effective RTT, applies a packet loss overhead multiplier (1.0×–2.5×), and computes timeout utilization as a percentage to classify risk as Low (<60%), Medium (60–80%), or High (>80%).

Covers ATM Withdrawal, ATM Deposit, POS Authorization, Teller Session, and ACH Transfer with ISO 8583-aligned round-trip presets. Recommends a safe timeout with 2× headroom and caps against practical per-type limits. Includes a step-by-step calculation derivation for transparency.
