MORTGAGE FORMULAS

LOAN
L = House × (1 − deposit)
Deposit is entered as a percent.
MONTHLY RATE
i = annual rate ÷ 12
The annual rate is converted to monthly decimal rate.
PAYMENT
PMT = L·i ÷ [1−(1+i)^−N]
N is term years multiplied by 12.
INTEREST
Interest = total − loan
This estimates mortgage interest.

WORKED EXAMPLES

LOAN
£200000 with 10% deposit
Mortgage loan is £180000.
PAYMENT
£180000, 4.5%, 25 years
Monthly repayment is about £1000.
TOTAL
Payment × 300 months

INTEREST
Total repaid − loan
Shows estimated interest over the term.

PAYMENT MODE

Payment mode estimates the monthly repayment for a repayment mortgage.

Enter house price, deposit, rate and term.

The loan can be calculated automatically or edited directly.

Overpayment adds a fixed extra amount to each monthly payment.

TERM AND RATE MODES

Term mode estimates how many years are needed from loan, rate and payment.

Rate mode estimates the annual rate that matches the payment and term.

Both are estimates and may differ from lender calculations.

Invalid or impossible inputs show CHECK rather than a false answer.

WHO USES IT

Buyers use it to estimate possible monthly mortgage repayments.

Owners use it to test remortgage rates, terms and overpayments.

Budgeters use it to compare payments against household income.

Students use it for repayment, interest and percentage practice.
