How is the monthly payment calculated?

It uses the standard amortisation formula, which spreads principal and interest evenly across every payment so the loan clears exactly at the end of the term.

Why is so much of my early payment interest?

Interest is charged on the remaining balance, which is highest at the start. As the balance falls, more of each payment goes to principal.

Nothing you enter leaves your device

All of the work happens inside your browser. Whatever you type is never packaged up and sent to a server, and no request this page makes carries it.

That makes it safe for contract amounts, personal details and internal documents you would rather not hand to a third party — close the tab and it is gone.

What this tool does not do

Loan Payment Calculator only does what a browser can do on its own — it talks to no backend service. So it keeps no history for you and syncs nothing across devices; if you need a record, copy or download the result.

It is also not a substitute for professional judgement. For legal, medical or tax decisions, treat the output as a starting point rather than a final answer.
