Mortgage Interest “Front-Loaded”? Myth vs Math

Part of: Loan Payments Explained

No secret fee schedule—just interest = f(balance). High balance early, high interest early.

Direct answer

Interest is not “front-loaded” as a separate punishment. Early payments are interest-heavy because you still owe nearly the full principal. Interest scales with balance; high balance → high interest charge.

What people feel vs what happens

Myth:   “They take all interest up front.”
Math:   Each period: interest on current balance; principal pays down remainder.
Result: Early years feel expensive because the balance is slow to fall.

See the curve

Open an amortization schedule: the interest column starts high and falls as principal column rises. Same scheduled payment throughout—changing mix, not a hidden schedule.

FAQ

Do extra payments “fix” front-loading?

Extra principal reduces the balance faster, so future interest drops. There was no separate front-load to remove—just less balance to charge against.
