Mortgage Calculation Formula Explained
This calculator uses the standard fixed-rate mortgage formula, which is widely used by financial institutions.
Monthly Payment Formula:
M=1−(1+r)−nP⋅r
Where:
- M = Monthly mortgage payment
- P = Loan amount (principal)
- r = Monthly interest rate
- n = Total number of payments (months)
How the Formula Works
- The annual interest rate is divided into monthly interest.
- The loan term is converted into total months.
- The formula calculates equal monthly payments over time.
- Total repayment and interest are derived from monthly values.
This ensures every monthly installment remains consistent throughout the loan period.
Step-by-Step Example Calculation
Let’s understand with a real-life example.
Loan Details:
- Loan Amount: $300,000
- Interest Rate: 5% per year
- Loan Term: 30 years
Step 1: Convert Values
- Monthly interest rate = 5 ÷ 100 ÷ 12 = 0.004167
- Total months = 30 × 12 = 360
Step 2: Monthly Payment
Using the mortgage formula:
Monthly payment ≈ $1,610.46
Step 3: Total Payment
Total payment = $1,610.46 × 360
= $579,765.60
Step 4: Total Interest
Total interest = $579,765.60 − $300,000
= $279,765.60
Final Result Summary:
- Monthly Payment: $1,610.46
- Total Payment: $579,765.60
- Total Interest: $279,765.60
This example clearly shows how interest significantly increases the total cost of a home loan.

Understanding Mortgage Payments Better
A mortgage payment is made up of two main components:
Principal
The original loan amount borrowed from the bank.
Interest
The cost charged by the lender for borrowing money.
In the early years of a mortgage, a larger portion of your payment goes toward interest. Over time, more of your payment goes toward reducing the principal.
Factors That Affect Mortgage Calculations
Several factors influence your mortgage payments:
1. Interest Rate
Even a 1% change can significantly affect total repayment.
2. Loan Term
Longer terms reduce monthly payments but increase total interest.
3. Loan Amount
Higher loan amounts naturally increase monthly payments.
4. Repayment Frequency
Monthly payments are standard, but other schedules may change total cost.
