Periodic Loan Payment
Why do real estate investors use the Periodic Loan Payment?

Formula
Periodic Loan Payment
Loan Amount = Purchase Price − Downpayment
Periodic Loan Payment = Loan Amount ×
[
i(1 + i)n
/
((1 + i)n − 1)
]
Where i = Monthly Interest Rate and n = Total Number of Months
Step-by-Step Example
Step 1
Purchase Price
$3,500,000
Enter the property purchase price or appraised value.
Step 2
Downpayment
$1,000,000
Enter the investor's upfront equity contribution.
Step 3
Loan Amount
Loan Amount = $3,500,000 − $1,000,000
$2,500,000
Step 4
Monthly Interest Rate & Term
Monthly Interest Rate = 6% ÷ 12 = 0.5% = 0.005
Total Number of Months = 25 × 12 = 300
Step 5
Periodic Loan Payment
$2,500,000 × [0.005(1 + 0.005)^300 / ((1 + 0.005)^300 − 1)]
$16,107.50
Final Result
$16,107.50
Periodic Loan Payment = $16,107.50. Use this fixed monthly obligation to pressure-test NOI and debt coverage before making an offer.
