Mortgage Calculation Formula Explained
The calculator uses a standard mortgage amortization formula to determine monthly payments.
Monthly Mortgage Payment Formula:
M=1−(1+r)−nP×r
Where:
- M = Monthly payment
- P = Loan principal (loan amount)
- r = Monthly interest rate (annual rate ÷ 12 ÷ 100)
- n = Total number of payments (loan term in months)
Total Payment Formula:
Total Payment=M×n
Total Interest Formula:
Total Interest=Total Payment−Loan Amount
Example Calculation
Let’s understand how the calculator works with a real example:
Loan Details:
- Loan Amount: $300,000
- Interest Rate: 5% per year
- Loan Term: 30 years
Step 1: Convert Values
- Monthly interest rate = 5 ÷ 12 ÷ 100 = 0.004167
- Total months = 30 × 12 = 360
Step 2: Monthly Payment
Using the formula:
👉 Monthly Payment ≈ $1,610.46
Step 3: Total Payment
👉 $1,610.46 × 360 = $579,765.60
Step 4: Total Interest
👉 $579,765.60 − $300,000 = $279,765.60
What Affects Your Mortgage Payment?
Several factors influence your mortgage cost:
1. Loan Amount
Higher loan amounts increase monthly payments.
2. Interest Rate
Even a 1% difference can significantly change total interest.
3. Loan Term
Longer terms reduce monthly payments but increase total interest.
4. Credit Score
A better credit score often results in lower interest rates.
5. Down Payment
Higher down payment reduces loan principal and total cost.
