Why extra payments work so well
A fixed-rate payment is front-loaded with interest: early on, most of each payment covers the interest on a large balance, and only a sliver reduces principal. An extra principal payment skips that interest entirely — it permanently removes that dollar from the balance, so it never accrues interest again for the remaining years of the loan.
Because the effect compounds over decades, small extra amounts have outsized results. The chart above contrasts your standard paydown with the accelerated one; the gap between the lines is interest you keep.

How we calculate this
We amortize your loan month by month, then re-run it adding your extra principal to each payment. Biweekly is modeled as its cash-flow equivalent — one extra payment per year. Planning estimates only — not financial advice.
Estimates for general informational purposes only and not financial advice. Confirm your loan has no prepayment penalty and that extra payments are applied to principal. Actual figures depend on your servicer's posting rules.
