Mortgage Monthly Payment Calculator
Estimate your monthly home loan repayments and total interest costs.
How to Use the Mortgage Payment Calculator
Planning a home purchase requires a clear understanding of your long-term financial commitments. This calculator helps you break down the cost of a mortgage into manageable monthly figures. Simply enter the purchase price of the home, the amount you plan to pay upfront (down payment), the current market interest rate, and the duration of the loan.
Understanding the Calculation
The calculator uses the standard amortization formula to determine your fixed monthly payment. This payment includes both the principal repayment and the interest charged by the lender. The formula used is:
M = P [ i(1 + i)^n ] / [ (1 + i)^n – 1 ]
- M: Total monthly payment.
- P: Principal loan amount (Home Price – Down Payment).
- i: Monthly interest rate (Annual rate divided by 12).
- n: Number of months (Loan term in years multiplied by 12).
Example Scenario
Suppose you are buying a home for $400,000 with a $80,000 down payment (20%). Your loan amount would be $320,000. If you secure a 30-year fixed rate at 6.5%, your monthly principal and interest payment would be approximately $2,022.62. Over the life of the loan, you would pay a total of $408,144.33 in interest.
Important Considerations
Keep in mind that this calculator provides an estimate for the Principal and Interest (P&I) only. In a real-world scenario, your monthly mortgage bill will likely include other costs such as:
- Property Taxes: Usually calculated annually and divided by 12.
- Homeowners Insurance: Required by lenders to protect the asset.
- Private Mortgage Insurance (PMI): Typically required if your down payment is less than 20%.
- HOA Fees: If you are purchasing a condo or a home in a managed community.
