Mortgage Calculation Formula Explained
The calculator uses a standard Compound Interest (scientific_concept) formula used in financial mathematics.
Monthly Mortgage Payment Formula:
M=(1+r)n−1P×r×(1+r)n
Where:
- M = Monthly payment
- P = Loan principal (amount borrowed)
- r = Monthly interest rate (annual rate ÷ 12 ÷ 100)
- n = Total number of months (years × 12)
Understanding the Formula
Loan Principal (P)
This is the original amount you borrow from the bank.
Interest Rate (r)
The bank charges interest annually, but repayments are calculated monthly.
Loan Term (n)
The total number of months determines how long you will repay the loan.
Total Payment Formula
Total Payment=Monthly Payment×Number of Months
Total Interest Formula
Total Interest=Total Payment−Loan Amount
This shows how much extra money you pay to the bank over time.
Example Calculation
Let’s understand with a real-life example:
Loan Details:
- Loan Amount = $200,000
- Interest Rate = 5% per year
- Loan Term = 20 years
Step 1: Convert Values
- Monthly interest rate = 5 ÷ 12 ÷ 100 = 0.004167
- Months = 20 × 12 = 240
Step 2: Monthly Payment
Using the formula, the monthly payment is approximately:
👉 $1,319.91
Step 3: Total Payment
$1,319.91 × 240 = $316,778.40
Step 4: Total Interest
$316,778.40 − $200,000 = $116,778.40
Final Result:
- Monthly Payment: $1,319.91
- Total Payment: $316,778.40
- Total Interest: $116,778.40
This example clearly shows how interest increases total loan cost over time.
