Example Calculation

Let’s see how the calculator works with a practical example:

Loan Amount: $300,000
Annual Interest Rate: 5%
Loan Term: 30 years

Step 1: Calculate Monthly Interest Rate
Monthly Rate = Annual Rate ÷ 12 ÷ 100
= 5 ÷ 12 ÷ 100
= 0.004167

Step 2: Calculate Total Payments
Total Payments = Loan Term × 12
= 30 × 12
= 360 months

Step 3: Calculate Monthly Payment
Monthly Payment = (Principal × Monthly Rate) ÷ (1 − (1 + Monthly Rate)^−Total Payments)
= (300,000 × 0.004167) ÷ (1 − (1 + 0.004167)^−360)
≈ $1,610.46

Step 4: Calculate Total Payment and Interest
Total Payment = Monthly Payment × Total Payments ≈ $579,767.60
Total Interest = Total Payment − Principal ≈ $279,767.60

With this calculation, you can see exactly how much you’ll pay each month and over the life of your mortgage.
