Mortgage Payment on a $300,000 Home

Buying a 300,000 home is a milestone for many families. This walkthrough calculates the full monthly payment including principal, interest, property taxes, insurance, and HOA. Confirm every figure using the Mortgage Payment Calculator.

Scenario Setup

  • Home price: 300,000
  • Down payment: 60,000 (20%)
  • Loan amount: 300,000 − 60,000 = 240,000
  • Annual interest rate: 6.5%
  • Term: 30 years
  • Property tax: 3,600/year
  • Home insurance: 1,200/year
  • HOA: 250/month

Step-by-Step Calculation

Monthly interest rate: 6.5 / 100 / 12 = 0.005417

Total payments: 30 × 12 = 360

Compounding factor: (1.005417)360 = 6.99157

PMT = 240,000 × 0.005417 × 6.99157 / (6.99157 − 1)

PMT = 240,000 × 0.037868 / 5.99157 = 9,088.32 / 5.99157 = 1,516.96

Monthly tax: 3,600 / 12 = 300

Monthly insurance: 1,200 / 12 = 100

Full monthly payment: 1,516.96 + 300 + 100 + 250 = 2,166.96

Result Interpretation

  • Principal and interest: 1,516.96/month
  • Full monthly payment: 2,166.96
  • Total P&I over 30 years: 546,106.77
  • Total interest paid: 306,106.77

The interest alone exceeds the original loan amount. This is a sobering reminder of how costly a 30-year term can be, even at a moderate rate. Nearly 56 percent of your principal-and-interest payments over the full term goes to interest.

Comparison: 15-Year Term

Switching to a 15-year mortgage on the same 240,000 at 6.5 percent:

  • Monthly P&I: 2,090.66
  • Total P&I: 376,318.38
  • Total interest: 136,318.38

The monthly payment increases by about 574, but total interest drops by roughly 169,788. That is a dramatic saving for borrowers who can handle the higher payment. As discussed in how mortgage interest is calculated, the shorter term means less time for interest to accumulate on the balance.

Practical Takeaway

Always calculate the full payment, not just principal and interest. Taxes, insurance, and HOA add 650 per month in this scenario, pushing the true cost well above the P&I figure. Use the Mortgage Payment Calculator to ensure the full payment fits within 28 percent of your gross income before making an offer.
