Mortgage Calculator

Mortgage Calculator is an online loan tool that helps you quickly work out the monthly payment, total interest and total repayment, and clearly compare the differences between repayment methods. Whether you are budgeting for your first home or evaluating interest savings before an early repayment, a few simple inputs give you clear results.

Key Features

• Single and combination loans: Supports pure commercial loans, pure housing fund loans, and combination loans that mix both. For combination loans, the two parts are calculated separately and merged period by period.
• Two repayment methods compared: Shows monthly payment, total interest and total repayment for both equal installments (fixed payment) and equal principal (decreasing payment), and automatically highlights the interest difference between them.
• Full amortization schedule: Generates a complete repayment table listing payment, principal, interest and remaining balance for every period, switchable between the two methods.
• Term slider: Adjustable from 1 to 30 years, recalculating instantly as you drag so you can compare payments and interest across terms.
• Export and copy: Export both repayment plans to an Excel file with one click, or copy the result text for saving and sharing.

Who Is It For

• Home buyers who need to estimate monthly payments before purchasing.
• Borrowers comparing interest costs between equal installments and equal principal.
• Users with housing fund or combination loans who need separate calculations.
• Mortgage holders considering early repayment and evaluating remaining balance and interest.

How to Use

1. Choose the loan type: single loan or combination loan.
2. Enter the loan amount and annual rate. For combination loans, fill in the amount and rate for both the housing fund and commercial parts.
3. Drag the slider to set the loan term.
4. The page automatically calculates and displays the monthly payment, total interest, total repayment and interest difference for both methods.
5. Switch to view the schedule, and export to Excel or copy the results when needed.

Key Concepts

Equal installments means a fixed payment each month, with a higher interest share early on that gradually shifts toward principal, suiting borrowers who prefer stable, predictable payments. Equal principal means a fixed principal repayment each month with interest decreasing as the balance falls, so payments decrease over time and total interest is usually lower, though early payments are higher. The monthly rate is the annual rate divided by 12, and the final period settles any remaining balance.

FAQ

Q: Is this mortgage calculator free?

A: Completely free. No registration or login is required, and there is no limit on the number of calculations.

Q: Should I choose equal installments or equal principal?

A: Equal installments keep payments fixed and easier to budget, with slightly higher total interest. Equal principal has higher early payments but lower total interest. Use the interest difference shown by the tool together with your cash flow to decide.

Q: Do the results exactly match my bank's figures?

A: Results are calculated with standard formulas and serve as a reference. Actual payments may differ slightly due to bank interest rules, disbursement and payment dates, so the bank contract prevails.

Q: Does it work on mobile devices?

A: Yes. The page uses a responsive layout and works well on phones, tablets and desktop computers.
