How the balance is advanced
This schedule first finds a fixed payment, then charges monthly interest on the unpaid balance before applying the rest of that payment to principal. The remaining balance after a chosen count of payments is the original balance plus accrued interest minus all modeled payments.
Five years into the default schedule
A $200,000 loan at 6% for 30 years has about $186,108.71 remaining after 60 payments. By then, $13,891.29 of principal has been repaid while $58,054.78 has gone to interest. The early balance falls slowly because interest begins on a large amount.
Schedule assumptions
The calculation assumes every payment arrived on time and was applied under a standard monthly schedule. It does not capitalize unpaid interest, add late charges, change the rate, or handle a lender that uses daily interest or a different first-payment period.
Cash paid versus balance reduced
Do not confuse total cash paid with equity gained. During the first five years of this example, the borrower has made many payments, yet the principal reduction is much smaller than the total of those payments.
When a payoff differs
A payoff quote can differ because it is dated to a particular day and may include per-diem interest, escrow, or a fee. This page is unsuitable for a revolving line of credit, an interest-only phase, or a loan whose payment changes with an index.
Planning from a remaining balance
Use the balance result to plan a sale, refinance, or extra-principal strategy. For a transaction, request the servicer's dated payoff statement rather than treating an illustrative schedule as the settlement amount.
A date matters to a balance
The number of payments made is a proxy for time, not a settlement date. A balance shown immediately after a payment differs from one shown just before the next due date, when another period of interest has accrued. For a sale or refinance, use the actual requested payoff date and do not substitute a rounded monthly schedule for the servicer's quote.
Interest allocation is not an account history
The model allocates a regular payment mechanically. A real account can apply an overpayment, suspense balance, or escrow adjustment under servicing rules that change the statement without changing the original note.
