📊 Mortgage Calculation Formula Explained
The calculator uses a standard mortgage formula used worldwide:
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 payments (years × 12)
🔍 Formula Breakdown
- The interest rate is divided into monthly segments
- The loan term is converted into total months
- The formula ensures equal monthly payments over the loan period
- Early payments consist mostly of interest, while later payments reduce principal
This structure is known as an amortized loan system.
📈 Example Calculation
Let’s assume:
- Loan Amount = $450,000
- Interest Rate = 5% per year
- Loan Term = 30 years
Step-by-step:
- Monthly interest rate = 5 ÷ 100 ÷ 12 = 0.004167
- Total months = 30 × 12 = 360
Using the formula, your estimated monthly payment is:
👉 $2,415.00 (approx.)
This means you will pay around $2,415 every month for 30 years.
