How it works

The five TVM variables are PV, FV, PMT, r (rate per period), and n (periods). Given any four, the calculator solves for the fifth. This underpins all financial planning: savings goals, loan comparison, lease vs. buy analysis, and investment evaluation. Cash flows are signed—outflows negative, inflows positive. Annuity timing (beginning vs. end of period) affects results.
