Rental Property Loan Calculation Formula

Our rental property loan calculator can help you understand how your loan payments are calculated to make more informed investment decisions. Below is the basic formula used in this real estate calculator to determine your monthly loan payment, along with a breakdown of each input field in our calculator.

M=P[(r(1+r)ⁿ)/((1+r)ⁿ-1)​]

Rental Property Loan Calculation Example

Suppose you’re purchasing a $350,000 rental property with a 25% down payment of $87,500, leaving a loan amount of $262,500. Your lender offers a 30-year fixed investment property loan at a 7% interest rate. Using the amortization formula above with a monthly rate of 0.583% (7% divided by 12) over 360 payments, the calculation would be:

$262,500 Loan Amount × 0.00665 Payment Factor
= $1,746 Monthly Principal and Interest

Over the full 30-year term, you would pay roughly $366,000 in total interest on top of the principal.

Now compare a 15-year term at the same rate. The monthly payment jumps to about $2,359, an extra $613 per month, but total interest falls to roughly $162,000, a savings of more than $200,000 over the life of the loan. The tradeoff is real: the lower 30-year payment protects monthly cash flow and DSCR, while the 15-year term builds equity dramatically faster.

Remember that this calculator estimates principal and interest only. Add property taxes, landlord insurance, and any HOA dues separately for your full monthly obligation. Use the rental property loan calculator above to compare rates, terms, and down payment amounts before locking in financing for your next investment property.

Rental Property Loan Calculator FAQ

Can I use this calculator for all types of rental properties?

Yes, this calculator is designed to work for a wide range of rental property types, including single-family rental homes, multi-family units, and commercial properties. It uses standard loan calculation methods that apply broadly across different residential investment properties. However, unique property types or specialized financing arrangements may require additional calculations beyond what this tool provides.

Why do monthly payments change with different loan terms or rates?

Monthly payments are determined by both the interest rate and the length of the loan term. Lower interest rates and longer terms can decrease your monthly payment, but may increase total interest paid over the life of the loan. Understanding this relationship helps you find the right balance between monthly affordability and long-term cost.

Does this calculator factor in property taxes and insurance?

This calculator focuses on estimating your principal and interest payments only. For a complete monthly payment estimate, you’ll need to add property taxes, landlord insurance costs, and other recurring costs separately.
