FAQ
Common questions
How is this different from the loan calculator?
This version focuses on an existing balance and payoff speed rather than deriving the base loan payment.
Can extra payments really save money?
Yes. Extra payments reduce principal faster, which lowers the total interest charged over time.
Can I use this for credit card debt?
You can use it as a planning estimate, though revolving debt may have more variable behavior than a fixed loan.
Does the schedule go forever?
No. The calculator caps the schedule after a reasonable upper bound to avoid unrealistic loops.
Is my balance sent anywhere?
No. Everything runs locally in the browser.
