Weighted Average Maturity (WAM) Calculator
Value-weighted average maturity of up to four holdings — the WAM that money-market and debt funds must disclose.
Formula
Regulators cap WAM to limit rate risk: US 2a-7 money funds at 60 days, SEBI overnight/liquid funds at 1/91 days. WAM uses final maturity (or rate reset for floaters) — pair with WAL, which ignores resets, for the full liquidity picture.
