A shop you trade from
Choose trading and enter the shop's yearly profit before the mortgage. Profit cover is that profit divided by the yearly mortgage payment. It shows how much room the accounts have for the repayment at the rate and term you enter.
Lenders also look at cash flow, existing borrowing and how long the business has traded. The calculator does not do that. It uses only the profit figure you enter.
A shop let to a tenant
Choose let and enter the annual rent and the rent-cover ratio. Rent cover is the rent divided by the annual interest. The largest loan the rent supports is the rent divided by the rate and by that ratio, and it cannot be more than the price.
The loan from the deposit is compared with that figure. Where the rent supports less, the rent test is the limit. Where the deposit is the tighter constraint, the loan stays at the price less the deposit. How leases are read is covered in shop and retail mortgages.
Frequently asked questions
Does this work for a shop with a flat?
As a rough loan and rent test, yes. A flat above a shop can change which lenders and loan-to-value limits apply.
What rent cover should I enter?
The ratio from a quote or illustration. Lenders set their own, and it varies with the tenant and the lease.
Does it include stamp duty and fees?
No. The loan is the price less the deposit. Stamp duty, legal fees and fit-out need adding to the cash required.
Is the result an offer?
No. It is an estimate from the figures you enter. A lender values the shop and checks the business or the lease.
