Buying a home is one of the biggest financial decisions you will ever make, and understanding the true cost is essential before signing the deal. While most people focus on the monthly mortgage payment, many forget about the closing costs—fees and expenses due at the final stage of the transaction. These can include loan origination fees, appraisal costs, title insurance, legal fees, and more

Formula for Mortgage Payment and Closing Cost Calculation
Monthly Mortgage Payment Formula
M = P × [ r(1 + r)ⁿ ] / [ (1 + r)ⁿ – 1 ]
Where:
- M = Monthly payment
- P = Loan principal (home price – down payment)
- r = Monthly interest rate (annual rate ÷ 12)
- n = Total number of monthly payments (years × 12)
Closing Cost Calculation
Total Closing Costs = Σ (All Individual Closing Fees)
This includes:
- Loan origination fees
- Title insurance
- Appraisal fees
- Recording fees
- Prepaid property taxes and insurance
Examples of Mortgage and Closing Cost Calculations
Example 1: Standard Loan
- Home price: $300,000
- Down payment: $60,000
- Loan amount: $240,000
- Loan term: 30 years (360 months)
- Interest rate: 5% annually (0.004167 monthly)
Mortgage Payment:
M = 240,000 × [0.004167 × (1 + 0.004167)³⁶⁰] / [(1 + 0.004167)³⁶⁰ – 1] ≈ $1,288.37
Closing Costs:
Loan origination: $2,400
Title insurance: $900
Appraisal: $500
Recording fees: $300
Total = $4,100
Example 2: First-Time Homebuyer with Lower Down Payment
- Home price: $200,000
- Down payment: $20,000
- Loan amount: $180,000
- Interest rate: 4%
- Loan term: 20 years
Mortgage payment ≈ $1,090.91
Closing costs = $3,500
