Buying a home or taking a loan is one of the biggest financial decisions in life. Before committing, it is essential to understand how much you will pay every month, the total cost of the loan, and how much interest you will end up paying over time. This is exactly where a Mortgage Payment Calculator becomes extremely useful.

This helps borrowers understand the real cost of borrowing before signing any loan agreement.

Mortgage Calculation Formula Explained
This calculator uses the standard mortgage amortization formula to determine monthly payments.
Monthly Payment Formula:
M=P×(1+r)n−1r(1+r)n
Where:
- M = Monthly Payment
- P = Loan Amount (Principal)
- r = Monthly Interest Rate (Annual Rate ÷ 12 ÷ 100)
- n = Total Number of Payments (Years × 12)
Breakdown of the Formula
1. Principal (P)
This is the original loan amount you borrow.
2. Interest Rate (r)
Annual interest is converted into a monthly rate because payments are made monthly.
3. Loan Term (n)
Total number of monthly payments over the loan duration.
Example of Mortgage Calculation
Let’s understand with a real example:
Loan Details:
- Loan Amount: $150,000
- Interest Rate: 6%
- Loan Term: 20 years
Step-by-Step Result:
- Monthly Interest Rate = 6 ÷ 12 ÷ 100 = 0.005
- Total Months = 20 × 12 = 240
After applying the formula:
- Monthly Payment ≈ $1,074.65
- Total Payment ≈ $257,916
- Total Interest ≈ $107,916
This example shows how much extra you pay in interest over the life of the loan.
