Loan & Mortgage Calculator.

A loan is quoted as a monthly repayment — a comfortable-looking number. What it rarely shows you is the total interest you hand over across the years, or how much a small overpayment quietly saves.

Put in the amount, the rate and the term. See the repayment, the true lifetime cost, and where the room to improve it sits — the same lens B3 uses with clients before they sign, opened up for anyone.

Before you type a single number: nothing you enter here leaves this page. The sums happen in your browser and disappear when you close it. No storage, no tracking of your figures, no follow-up you didn't ask for.
Your loan

The loan

The loan or mortgage principal.
The reducing-balance rate the bank quotes. If you were quoted a "flat" rate, the true cost is higher — worth asking.
How long you'll repay over.
Anything you'd add on top of the required repayment. Leave at 0 if none — we'll still show you what a little would do.
To run the numbers we need the amount, the interest rate and the term.

Estimates are fine. The shape of the cost matters more than the decimals.

Indicative only. A quick picture, not a plan or personalised advice. Always check official sources or speak to an adviser before you act — what these numbers mean for you is the conversation.

Comparing two offers

Two quotes, side by side.

Two loans can look a fraction apart and be much further apart than that. The rate is only part of it — how the interest is worked out, and what is charged up front, often matter more.

Offer A

If you are not told, ask. It changes the cost a great deal.
Processing, arrangement, insurance or solidarity contributions taken at the start.

Offer B

If you are not told, ask. It changes the cost a great deal.
Processing, arrangement, insurance or solidarity contributions taken at the start.

Enter an amount, a rate and a term for both offers.

How much, and what would it cost

Work it from either end.

What you could comfortably pay every month, not the most you could survive.
Reducing balance. Use a rate you have actually been quoted where you can.
Longer lowers the monthly figure and raises the total cost.
Only used to show what share of your income the repayment would take. Leave blank to skip.

Fill in the amount or repayment, plus a rate and a term.

The next step — if you want one

Before you sign, know whether this is the right debt, at the right cost.

A repayment on a screen can't see the fee-loaded APR behind a low headline rate, the Mauritius home-loan interest relief you may be owed, whether overpaying beats investing, or whether you should be borrowing this much at all. That's what a conversation is for. Fifteen minutes, no charge, and we'll tell you plainly whether B3 is the right fit — including when it isn't.

What the fifteen minutes actually is
  • You talk, we listen — the purchase, the loan on the table, and what's on your mind.
  • You leave with one or two honest observations, free, whether or not we ever work together.
  • If B3 can help, we'll show you how. If it can't, we'll say so plainly. No product, no pitch.
