Commercial mortgage calculator

Monthly payment, total interest, and the check most calculators skip: what the payment looks like at a stressed rate, because that is the arithmetic a lender will actually run on your deal.

Illustrative only. Lender arrangement fees (typically 1-2%), valuation and legals are extra. Trading businesses are assessed on adjusted earnings, not just the payment; this is not an offer of finance.

The stressed payment is the real test

Lenders do not ask whether the business can afford today's payment; they ask whether it could still pay if rates rose, usually testing around two points above the pay rate with headroom on top. If your deal only works at the headline rate, it will die at underwriting. We run this arithmetic on your real accounts before any application goes in, which is why the number we quote is a number that completes.

FAQ

What rate should I put in?

Commercial mortgage pricing varies with the business, the property and the loan-to-value; strong trading deals price keenest. If you have no quote yet, try a realistic range rather than one number, and note how much the payment moves.

What is the stressed payment for?

It shows the payment at your rate plus two percentage points, which is close to how lenders test serviceability. If the stressed payment would strain the business, expect lenders to trim the loan; better to know now than at underwriting.

Capital and interest, or interest-only?

Most owner-occupier commercial mortgages are capital and interest. Interest-only appears on investment deals with a clear exit. Interest-only payments are lower, but the debt does not shrink; the calculator shows both totals honestly.
