Principal vs Interest breakdown
How this calculator works
A mortgage payment has two core components: principal (the loan balance you're repaying) and interest (the cost of borrowing). On a standard 30-year fixed mortgage, early payments are mostly interest — that gradually shifts toward principal over time.
Your total monthly payment may also include property taxes, homeowner's insurance, and PMI (Private Mortgage Insurance) if your down payment is below 20%. This calculator lets you include those to see your true all-in monthly cost.
The amortization schedule shows exactly how each payment is split between principal and interest across every year of your loan. Use it to understand how extra payments can dramatically reduce your total interest paid.
Worked example
A $450,000 home with 20% down at 7.0%
- 1Monthly rate: 7.0% ÷ 12 = 0.5833%
- 2Months: 30 × 12 = 360
- 3Monthly P&I = $360,000 × [0.005833 × (1.005833)^360] ÷ [(1.005833)^360 - 1]
- 4Monthly P&I = $2,395/month
- 5Total paid over 30 years: $2,395 × 360 = $862,200
- 6Total interest paid: $862,200 − $360,000 = $502,200
