Example 1
- Amount: 400,000
- Rate: 7%
- Term: 25 years
Payment 2,827.12
Total 848,135.04
Interest 448,135.04
A classic scenario: at 7% over 25 years, interest ends up exceeding the amount borrowed.
Mortgage calculator
Type the mortgage, the yearly rate, and the repayment years. The calculator computes principal plus interest. At 400,000, 7%, and 25 years the payment is 2,827.12, the total is 848,135.04, and interest is 448,135.04. From price and down payment you also get LTV, loan to value, the loan divided by the property value.
Annuity payment plus optional housing cost. LTV from price and down payment. Full table: amortization schedule. A payment sketch, not full mortgage underwriting.
Result
Loan amount, Annual interest rate (%), Term (years) and Property price (optional). The result shows up here.
How results are calculated
The mortgage payment calculator builds a fixed installment, an annuity, from amount, annual rate, and term in years. At 400,000, 7%, and 25 years the payment is 2,827.12. Three hundred payments total 848,135.04, and interest is 448,135.04. If you type Property price and Down payment, the calculator derives the loan and LTV, loan to value, the loan divided by the property value. 500,000 minus 100,000 is a 400,000 loan and 80% LTV.
People open this calculator when they want the payment and housing cost on one page. Annual property tax, Annual home insurance, and Monthly HOA / admin fee stack onto housing cost outside the contractual payment. At a 500,000 price, a 100,000 down payment, 6.5%, and 30 years the payment is about 2,528, and housing with tax 6,000, insurance 2,400, and HOA 250 is about 3,478. That is still a sketch, not a full capacity review and not a credit decision.
Required fields when the loan is known are Loan amount, Annual interest rate (%), and Term (years). You can leave price and down payment blank if you already know the loan. Monthly extra payment goes to principal above the installment and shows savings versus the base case. First payment date sets a payoff date. The calculator does not ask for a score, a minimum down payment from an offer, or bridge insurance.
At 250,000, 8%, and 20 years, an extra 300 a month shortens the term and cuts interest versus paying the contract only. The full table with a yearly or one-time extra lives on the amortization schedule. A down-payment percent lives on the down payment page. Bare LTV from a known loan lives on the LTV page.
Header currency only labels the amounts. A comma and a period in 6.5 mean the same rate. The calculator waits for an amount, or for price plus down payment, plus rate and term. This is a fixed-rate model, not full mortgage underwriting.
Type 400,000, 7, and 25, click Calculate, and check 2,827.12. Then try price 500,000, down 100,000, 6.5, and 30 to see 80% LTV and housing near 3,478.
How to use
- Type Loan amount, for example 400,000, or enter Property price and Down payment so the calculator can derive the loan and LTV.
- Type Annual interest rate (%), for example 7, and Term (years), for example 25.
- Optionally add Annual property tax, Annual home insurance, Monthly HOA / admin fee, and Monthly extra payment.
- Click Calculate. At 400,000, 7%, and 25 years the payment is 2,827.12, the total 848,135.04, interest 448,135.04.
- For the full table, open the amortization schedule. An income-based cap lives on borrowing capacity, not here.
Mortgage payment and LTV from price and down
Principal-plus-interest annuity, optional LTV. At 400,000, 7%, and 25 years the payment is 2827.12 and the total is 848,135.04. Price 500,000 and down 100,000 is 80% LTV.
- payment
- Fixed principal plus interest. 400,000 at 7% for 25 years is 2827.12. Interest 448,135.04 exceeds the amount borrowed.
- LTV
- Loan to value from price and down payment in this calculator. 400,000 financed on a 500,000 price with 100,000 down is 80%. Not APR.
- Down payment
- Cash subtracted from price to get the loan and LTV. 100,000 of 500,000 leaves 400,000 financed and 80% LTV.
Usage examples
Example 2
- Price 500,000, down 100,000 (LTV 80%)
- 6.5%, 30 years
- Tax 6,000/yr, insurance 2,400/yr, HOA 250/mo.
Payment ≈ 2,528
Housing ≈ 3,478
LTV 80%
The mortgage payment alone is not the full budget - tax, insurance, and HOA raise the monthly cost.
Example 3
- Amount: 250,000
- 8%, 20 years, start Jan 1, 2026
- Extra +300/mo.

How to read this calculator
- This calculator combines the mortgage instalment with the broader context of housing cost, so the result is wider than the pure principal-and-interest payment alone.
- If you enter the property price and down payment, you can also see how the financing setup relates to concepts such as LTV.
- If you need a simple cash-loan style payment without the property context, the simpler Loan payment calculator is a better fit.
Related concepts
- A mortgage instalment is not always the same as the full monthly housing cost if taxes, HOA/service charges, insurance, or other fixed costs are added.
- LTV describes the loan-to-value relationship, while creditworthiness describes whether that financing level is realistic for your budget.

FAQ
What is the payment on 400,000 at 7% for 25 years?
2,827.12. Total 848,135.04, interest 448,135.04. That is an annuity, an equal installment, at a fixed rate.
What LTV do I get at a 500,000 price and a 100,000 down payment?
Loan 400,000, LTV 80%. LTV is loan to value, the loan divided by the property value. At 6.5% for 30 years the payment is about 2,528.
Where does housing cost of about 3,478 come from?
Payment about 2,528 plus 6,000/12 tax, 2,400/12 insurance, and 250 HOA. 2,528 + 500 + 200 + 250 = 3,478.
Does an extra 300 reduce the 2,827.12 payment?
No. The 300 goes to principal above the installment. The result is lower interest and a shorter term versus the base case.
Is this full mortgage underwriting?
No. There is no score, no offer minimum down payment, no bridge insurance, and no regulatory rate buffer. It is a payment and LTV sketch.
Where is the down-payment percent?
On the down payment page. Here you start from a loan or from price and a cash down payment, not from a percent slider.
Where is the full table of 300 payments?
On the amortization schedule. Here you see payment, total, interest, LTV, and housing cost.
Does a comma in 6.5 work?
Yes. 6,5 and 6.5 are the same rate. Header currency only labels the result.
How is this different from the cash-loan installment page?
Same annuity math. Here you also get price, down payment, LTV, and housing costs. The cash-loan card stays with shorter amounts and optional fees.
Is 2,827.12 a credit decision?
No. It is a fixed-rate sketch from the numbers you type. An offer and a capacity review are computed elsewhere.
Knowledge sources
The annuity payment uses the rate you type, plus optional housing cost. This is a sketch, not underwriting.
