Mortgage Payment Calculator
Calculate your monthly principal and interest payment.
What it does
Uses the standard amortization formula to calculate the fixed monthly P&I payment for a given loan amount, interest rate, and term.
Why it matters
Debt service is the largest single expense on a leveraged rental. Knowing the exact payment is the foundation of accurate cash flow analysis.
How to Use
- 1Enter loan amount: Purchase price minus your down payment.
- 2Enter annual interest rate: As a percentage (e.g., 7.5 for 7.5%).
- 3Enter loan term: In years. Investment properties commonly use 15 or 30 years.

Best Practices & Benchmarks
- •Investment property rates typically run 0.5–1.0% above primary residence rates. Use a real lender quote, not a national average.
- •Compare 15- vs. 30-year terms: a 30-year maximizes cash flow; a 15-year builds equity faster and saves significantly on total interest.
- •DSCR lenders often have different rate pricing than conventional lenders — shop both if you qualify for either.
- •Points and fees can lower your rate but increase upfront cost; calculate the break-even month to know when the lower rate pays off.
- •For adjustable-rate mortgages (ARMs), model cash flow at the cap rate (maximum possible rate), not just the teaser rate.
