Mortgage basics
How mortgage payments work
Home price
The purchase price sets the starting point for down payment and loan amount.
Down payment
The down payment is paid upfront and reduces how much you borrow.
Interest rate
The mortgage rate determines how much interest accrues on the remaining balance.
Amortization
Repayment mortgages gradually shift from mostly interest to more principal over time.
Formula
Mortgage formula explanation
Repayment mortgage
Payment = P × r × (1 + r)^n / ((1 + r)^n − 1)P is loan amount, r is monthly interest rate, and n is the number of monthly payments.
Interest-only mortgage
Monthly Interest = Loan Amount × Monthly RateInterest-only payments cover interest but do not reduce the principal balance.
Total monthly housing cost
PITI + PMI + HOA = Principal + Interest + Tax + Insurance + PMI + HOAThis calculator adds entered monthly housing costs to the mortgage estimate.
Cost drivers
What affects total mortgage cost
Home price
A higher purchase price usually increases the loan amount, down payment, and total cost.
Down payment
A larger down payment reduces loan amount and may help avoid PMI.
Interest rate
A higher rate increases monthly payment and total interest, especially over long terms.
Taxes and insurance
Property taxes and insurance can significantly increase the monthly housing payment.
PMI
PMI can add a monthly cost when the down payment is smaller than lender requirements.
HOA fees
HOA or service fees may be part of housing cost but do not reduce the mortgage balance.
Comparison
Shorter term vs lower rate
Shorter term estimate
£2,160.66

£1,816.92
At 5.50%, principal and interest may fall and total interest may be about £334,092.93.
