Frequently asked questions

Why do small extra payments help so much?

Extra money goes straight to principal, which reduces every future interest charge — the effect snowballs over decades.

Is paying off early always smart?

Compare your mortgage rate to other returns. If investments reliably beat your rate, investing may win — but guaranteed interest savings are appealing too.

Should I tell my lender it is extra principal?

Yes — specify that additional payments apply to principal, or some lenders credit them to future interest instead.
