How It Works

Monthly payments are calculated using the standard amortization formula: M = P × [r(1+r)n] / [(1+r)n - 1], where P is the loan principal, r is the monthly interest rate, and n is the total number of payments.

Early in the loan, most of each payment goes toward interest. Over time, the balance shifts so more goes toward principal. Extra monthly payments reduce the remaining balance faster, shortening the loan term and saving on total interest paid.

Inflation and fixed-rate debt: a fixed monthly payment stays the same in nominal terms but shrinks in real purchasing power over time. With 3% inflation, a $1,264 payment in year 30 is worth roughly $520 in today's dollars. This means inflation quietly reduces the true cost of long-term fixed-rate debt — a benefit to borrowers.
