Amortization Calculator

Compute a fixed amortizing payment plus total interest over the loan and how the first payment splits between interest and principal.

Inputs

M = P × i(1+i)^k / ((1+i)^k − 1)
first interest = P × i
first principal = M − first interest

i = APR/100/12, k = years×12. Summary only — not a full schedule table.
