Cost Breakdown
Understanding Mortgage Payments
A mortgage payment is the regular payment you make to repay your home loan. It typically includes four components, collectively known as PITI:
- Principal: The portion that reduces your loan balance
- Interest: The cost of borrowing money
- Taxes: Property taxes (often escrowed)
- Insurance: Homeowners insurance and PMI if applicable
Key mortgage concepts:
- Amortization: Gradual repayment through scheduled payments
- Fixed rate: Interest rate stays constant for loan term
- Adjustable rate (ARM): Rate changes after initial period
- Escrow: Account where taxes and insurance are held
Understanding your mortgage payment helps you budget effectively and make informed decisions about your home purchase.
Mortgage Payment Formula
The standard formula for calculating your monthly principal and interest payment:
Monthly Mortgage Payment
Where:
- M= Monthly payment (principal and interest)
- P= Principal loan amount
- r= Monthly interest rate (annual rate / 12)
- n= Total number of payments (years Γ 12)
Breaking Down PITI
Principal and Interest:
- Fixed amount each month (for fixed-rate loans)
- Early payments are mostly interest
- Later payments are mostly principal
- This is the core loan payment
Property Taxes:
- Typically 0.5-2.5% of home value annually
- Varies significantly by location
- Usually escrowed (paid monthly, held by lender)
- Can increase over time with assessments
Homeowners Insurance:
- Required by all lenders
- Typically $1,000-3,000+ annually
- Covers fire, theft, liability, etc.
- Flood insurance separate if in flood zone
Private Mortgage Insurance (PMI):
- Required if down payment is less than 20%
- Typically 0.5-1% of loan amount annually
- Can be removed once equity reaches 20-22%
- Protects lender, not you

Strategies to Reduce Mortgage Costs
Lower your interest rate:
- Improve credit score before applying
- Shop multiple lenders (3-5 minimum)
- Consider buying points (1 point = 1% of loan)
- Choose shorter loan term
Reduce PMI costs:
- Put 20% down to avoid PMI entirely
- Use piggyback loan (80-10-10)
- Request PMI removal at 20% equity
- Consider lender-paid PMI (higher rate)
Save on other costs:
- Shop homeowners insurance annually
- Appeal property tax assessments if too high
- Bundle insurance policies for discounts
- Consider areas with lower property taxes
Pay off faster:
- Make biweekly payments (one extra payment/year)
- Round up payments to nearest $100
- Apply bonuses and windfalls to principal
- Refinance to shorter term when rates drop
Worked Examples
Calculate Basic Mortgage Payment
Problem:
Calculate the monthly P&I payment for a $300,000 loan at 6.5% for 30 years.
Solution Steps:
- 1P = $300,000
- 2r = 6.5% / 12 = 0.5417% = 0.005417
- 3n = 30 Γ 12 = 360 payments
- 4M = $300,000 Γ [0.005417(1.005417)^360] / [(1.005417)^360 - 1]
- 5M = $300,000 Γ [0.005417 Γ 6.99] / [5.99]
- 6M = $300,000 Γ 0.00632
Result:
Monthly P&I payment is $1,896.20. Total paid over 30 years: $682,633. Total interest: $382,633.
