These are the real questions every home buyer faces before signing a mortgage contract.
Banks quote annual rates but never show you the monthly breakdown. Our monthly mortgage calculator converts your loan amount, term, and rate into an exact monthly payment in one click โ no spreadsheet needed.
Equal installment keeps your monthly mortgage payment fixed but costs more interest overall. Equal principal lowers your payment each month but starts higher. Most buyers guess without real numbers. Our mortgage calculator shows both plans instantly so you can compare side by side.
On a 30-year mortgage, interest can easily exceed the original loan amount. Without a monthly mortgage calculator, most buyers underestimate what they actually pay. The full amortization schedule reveals every dollar of interest charged over the life of your loan.
Most mortgage calculators only support one repayment mode. Ours compares both plans, shows the full amortization schedule, and saves your data locally.
Enter a direct loan amount or calculate from house price plus down payment ratio. The monthly mortgage calculator adapts to whichever stage of the home-buying process you are in.
Switch between equal installment and equal principal with a single click. Both methods run through the full mortgage calculator engine so you see the real trade-off in monthly payment and total interest.
The monthly mortgage calculator generates a complete payment schedule showing every period's payment, principal, interest, and remaining balance โ transparent down to the last dollar.
Enter your rate as LPR plus a custom spread in basis points โ the exact format Chinese banks use. The mortgage calculator automatically converts it to an annual rate for computation.
A built-in SVG chart visualizes how much of your total repayment is principal versus interest. One glance at the mortgage calculator chart tells you what years of statements cannot.
Your last mortgage calculator inputs are automatically saved in the browser. Refresh, close, and reopen โ your loan amount, term, and rate are right where you left them.
Three steps from input to full amortization schedule โ no signup, no download required.
Choose whether to enter the loan amount directly or to calculate it from the house price and down payment ratio. Then set the loan term (10, 20, or 30 years, or any custom value) and the annual interest rate.
Select equal installment for a fixed monthly mortgage payment throughout the term, or equal principal for a higher first payment that gradually decreases. Both options calculate instantly inside the mortgage calculator.
Check the summary cards for monthly payment, total interest, and total repayment. Then scroll to the full amortization schedule to see a period-by-period breakdown of every payment for the life of your mortgage.
Real use cases where the monthly mortgage calculator gives you a decisive financial edge.
Before making an offer on a home, use the monthly mortgage calculator to find the maximum loan amount that keeps your monthly payment within budget. Adjust the down payment ratio to see how it shifts the numbers โ and walk into every negotiation prepared.
Equal installment or equal principal? The monthly mortgage calculator puts both on screen at the same time. See the fixed payment versus the declining schedule, and see the total interest difference across the full loan term โ real numbers, not guesses.
The full amortization schedule from the mortgage calculator shows your exact remaining balance after any number of payments. Use it to identify the ideal moment to make a lump-sum prepayment and calculate exactly how much interest you would save.
Common questions about mortgage calculations and repayment planning.
For equal installment, the monthly mortgage calculator uses the standard amortization formula: M = P ร r(1+r)โฟ / ((1+r)โฟ โ 1), where P is the principal, r is the monthly interest rate (annual rate รท 12), and n is the number of monthly payments. For equal principal, the fixed principal per period is P รท n, and the interest component decreases each month as the remaining balance falls.
Equal installment keeps your monthly mortgage payment constant for the entire loan term, making it easier to budget. Equal principal fixes the principal repaid each month, so the total payment is highest at the start and decreases steadily. Equal principal typically costs less total interest, but the higher early payments require stronger cash flow.
Switch the rate input mode to 'LPR + Basis Points'. Enter the current LPR rate in the first field and your basis point spread in the second field. For example, LPR 3.1% + 80 BP gives an effective rate of 3.9%. The monthly mortgage calculator converts this automatically and uses it for all calculations.
Yes โ your inputs are saved automatically to your browser's LocalStorage. Refreshing or closing the tab will not erase your loan amount, term, or rate. Nothing is sent to any server: all mortgage calculation runs entirely on your device.
The pie chart visualizes what fraction of your total repayment amount is original principal versus total interest paid. On long-term loans โ especially at higher rates โ the interest slice is often larger than the principal slice, which is a powerful reminder of the real cost of borrowing.
Yes. The monthly mortgage calculator is currency-agnostic โ just enter your loan amount in whatever currency your bank uses. The formulas and amortization schedule work the same regardless of whether you are computing a mortgage in USD, CNY, EUR, or any other currency.
