Evaluate extra payments by comparing complete repayment schedules.
Use the Mortgage Payoff alongside this illustrative example.
A practical example
Start with the same outstanding balance, rate and remaining term in two scenarios. Leave extra payment at zero in the first; add a manageable hypothetical extra amount in the second. Compare the payoff date and total interest, then check how much additional cash the second scenario requires each month.
Check the result
Verify that your lender applies extras to principal and whether an early-repayment charge applies. A model’s saved interest can be offset by fees or a different allocation of payments.
Try a comparison
Compare a regular monthly extra payment with a scenario containing no extras, using identical starting assumptions. Record both the monthly commitment and the projected saved interest. A payoff comparison is meaningful only if the payment pattern is one you could actually sustain.
What this does not establish
A fixed-rate projection is not a forecast of changing rates. Keep emergency cash and other commitments in your own budget rather than assuming earlier payoff is always the best choice.
