SOLVE PMT—

Keypad entry: Present value

Choose the quantity to solve, then enter the other four. Money received is positive; payments made are negative. N counts payment periods. I/Y is nominal annual interest; payments and compounding use the same frequency. Equal payments and a constant rate are assumed; fees and taxes are excluded. The rate solver searches 0–1000% and returns a bracketed solution.

Formula references: PMT · FV. A cash-flow series may have multiple rates; the solver returns one bracketed nonnegative rate.
