Frequently asked questions

How does an extra payment save on interest?+

Any amount above the required payment goes straight to principal, which lowers the balance interest is calculated on for every remaining period. That reduction compounds, so a dollar paid early is worth more than a dollar paid late.

Should I make one extra payment a year or add a little to every payment?+

Both reduce the balance faster, but the calculator lets you compare: a single annual lump sum is easier to budget, while a monthly top-up starts saving interest sooner and compounds slightly more over time.

Will extra payments shorten my loan term or lower my monthly payment?+

Unless you ask your lender to re-amortize, extra payments shorten the term while your required payment stays the same — you finish paying off the loan earlier rather than paying less each month.

Is there a point where extra payments stop being worth it?+

Yes — once you're close to payoff, the remaining interest savings shrink, and it may be worth comparing that money against a higher-return use, like an emergency fund or a higher-interest debt.

Does the calculator assume the extra payment happens every period?+

It depends on the mode you choose: recurring extra payments apply every period from the start date you pick, while a one-time extra payment is applied once and the schedule recalculates from there.
