Mortgage Payment Formula Explained
The calculator uses a standard mortgage amortization formula used worldwide.
Monthly Mortgage Payment Formula:
M=(1+r)n−1P⋅r⋅(1+r)n
Where:
- M = Monthly payment
- P = Principal loan amount
- r = Monthly interest rate (annual rate ÷ 12 ÷ 100)
- n = Total number of payments (years × 12)
Understanding the Components
1. Principal (Loan Amount)
This is the total money borrowed from the lender.
2. Interest Rate
This is the cost of borrowing money, expressed annually.
3. Loan Term
In this calculator, the term is fixed at 25 years (300 months).
4. Monthly Payment
This is the fixed amount you pay every month.
Example Calculation
Let’s understand with a real-world example:
Scenario:
- Loan Amount = $200,000
- Interest Rate = 6%
- Loan Term = 25 Years
Step-by-Step Results:
| Item | Value |
|---|---|
| Monthly Payment | $1,289.99 |
| Total Payment | $386,997.00 |
| Total Interest | $186,997.00 |
Explanation:
- You borrow $200,000
- Over 25 years, you repay almost $387,000
- Nearly $187,000 is interest cost
This shows how important interest rates are in long-term loans.

What Affects Your Mortgage Payment?
Several factors influence your monthly mortgage:
1. Loan Amount
Higher loan = higher monthly payment.
2. Interest Rate
Even a 1% change can significantly impact total cost.
3. Loan Duration
Longer loans reduce monthly payments but increase total interest.
4. Repayment Structure
Fixed-rate loans keep payments stable over time.
Monthly Payment vs Total Cost
Many borrowers focus only on monthly payments, but the total cost matters more in the long run.
| Focus Area | What It Means |
|---|---|
| Monthly Payment | Short-term affordability |
| Total Payment | Full loan cost over 25 years |
| Total Interest | Cost of borrowing money |
