Why This Calculator is Important

- Plan your monthly budget
- Compare loan offers from different banks
- Avoid over-borrowing
- Understand total interest burden
- Make smarter investment decisions
Mortgage Calculation Formula Explained
The calculator uses a standard financial formula known as the fixed-rate mortgage formula.
Monthly Mortgage Payment Formula:
M=P×(1+r)n−1r(1+r)n
Where:
- M = Monthly payment
- P = Loan principal (amount borrowed)
- r = Monthly interest rate (annual rate ÷ 12 ÷ 100)
- n = Total number of monthly payments (years × 12)
Step-by-Step Breakdown:
- Convert annual interest rate into monthly rate
- Convert loan term into total months
- Apply compound interest formula
- Calculate fixed monthly payment
Understanding the Results
After calculation, the tool gives three important financial values:
1. Monthly Payment
This is the fixed amount you pay every month until your loan ends.
2. Total Payment
This is the total amount you will pay over the entire loan period, including principal and interest.
3. Total Interest
This shows how much extra money you pay to the bank as interest.
Example Calculation
Let’s understand with a real-life example:
Loan Details:
- Loan Amount: $200,000
- Interest Rate: 5% per year
- Loan Term: 30 years
Step 1: Monthly Rate
5% ÷ 12 = 0.004167
Step 2: Total Months
30 × 12 = 360 months
Step 3: Results
- Monthly Payment ≈ $1,073.64
- Total Payment ≈ $386,510.40
- Total Interest ≈ $186,510.40
What This Example Shows
Even though you borrow $200,000, you end up paying almost double over time due to interest. This is why mortgage planning is extremely important.
