PFCChoose a tool for the question you are answering
Mortgage amortization calculator
Estimate fixed principal-and-interest payments, follow the loan balance, and compare extra principal payments.
ARM mortgage calculator
Model an initial fixed period followed by rate resets using an assumed index, lender margin, caps, and floor.
Rent versus buy calculator
Compare projected wealth using housing costs, transaction costs, home appreciation, and invested savings.
Fixed payments or adjustable rates?
A fixed-rate calculation holds the rate constant. An ARM calculation follows the reset dates and rate assumptions you enter. Use the same loan amount and term when comparing the two, and review later payments as well as the initial payment.
Neither mortgage tool includes taxes, insurance, or other escrow charges. The rent versus buy tool models a broader set of housing expenses using a fixed mortgage.
