What taxes and insurance add to a commercial loan payment
On many commercial property loans the lender collects the yearly property tax and insurance with each payment and pays the bills for you from an escrow or reserve account. Freddie Mac's term sheet for its Optigo Conventional Small multifamily loan, for example, lists a tax and insurance escrow as generally required. The deposits are on top of the loan payment: they do not reduce the balance or change the interest, they only raise the cash you pay.
This calculator works out the loan payment from the purchase price, down payment, interest rate and term, then adds one payment's share of the yearly property tax and insurance. A lender may size the deposits differently, hold a cushion or add other reserves, so use the figure to plan and the lender's quote for the real number.
Worked example: a $500,000 commercial property
Buy a $500,000 property with a 25% down payment. The down payment is $125,000.00 and the loan is $375,000.00, a loan to value of 75.00%. At 7.25% over 20 years with a 1% origination fee deducted from the loan, the principal and interest payment is $2,963.91 a month.
Add $7,500 a year of property tax and $3,000 of insurance, which come to $875.00 a month. The regular payment with taxes and insurance is $3,838.91, and taxes and insurance are 22.79% of it. Over the 20-year term they add up to $210,000.00, so everything you pay to the lender comes to $921,338.39.
A larger property and a fixed down payment
If the seller or lender quotes the down payment in dollars, choose a fixed amount. On a $1,200,000 property with a $300,000 down payment, $18,000 of property tax, $7,200 of insurance and a 6.75% rate over 25 years, the loan is $900,000.00. The loan payment is $6,218.20, taxes and insurance add $2,100.00 and the regular payment is $8,318.20 a month.
Payments every two weeks or every week
The yearly tax and insurance are divided by the number of payments in a year. On a $350,000 property with a 20% down payment, $6,500 of tax and $2,400 of insurance, a payment every two weeks is $1,020.67 for the loan plus $342.31 for taxes and insurance, so $1,362.98 in all. The loan payment alone does not change when the tax bill does: with no tax or insurance, the default example above stays at $2,963.91.
Tax saving on interest and property tax
The IRS says you can generally deduct interest you pay on a loan if the money is used for your business, and the real estate taxes you pay on your business property. This page estimates the saving by applying one tax rate that you enter, your combined federal and state business rate, to the interest and the property tax. Principal, insurance, fees and the down payment are left out of the estimate.
At a 25% rate the example above saves $8,600.84 in the first year, which is a quarter of the first year's interest and property tax, and $121,584.60 over the scheduled term. Enter a rate of zero to hide the estimate. The saving also assumes the whole deduction can be used against profit, which may not be so: larger businesses can be limited by section 163(j), and the IRS gives $32 million of average annual gross receipts as the 2026 threshold for the small business exemption.
Paying off a loan that matures sooner
Many commercial loans amortize over 20 or 25 years but fall due sooner with a balloon payment. This calculator pays the loan off in full over the term you enter, so it understates the balance due at maturity. Use the balloon payment calculator to see the final payment, and keep the same tax and insurance estimate for the monthly cash.
To see the balloon at maturity, use the commercial loan balloon payment calculator.
For a general commercial mortgage payment, see the commercial mortgage calculator.
What this estimate leaves out
The model holds property tax and insurance flat for the whole term. Tax bills and premiums change, often every year, and a reassessment, a rate change or a different insurer can move the payment. It does not include private mortgage insurance, other lender reserves, fees you pay with each payment beyond the ones you enter, or state-specific tax rules. It is a planning estimate, not tax advice or a lender quote.

CALCULATOR QUESTIONS
US commercial loan calculator with taxes questions
How do I calculate a commercial loan payment with taxes and insurance?
Work out the principal and interest payment, then add the yearly property tax and insurance divided by the number of payments. A $375,000 loan at 7.25% over 20 years is $2,963.91 a month, and $10,500 of tax and insurance adds $875.00.
Do property taxes change the loan payment?
Not the loan itself. The principal and interest payment stays the same, and taxes and insurance are added on top, so only the total cash payment changes.
Is a tax and insurance escrow required on a commercial loan?
Often, but not always. It depends on the lender and the loan, so ask for the escrow terms in writing.
Is commercial loan interest tax deductible?
Generally yes if the money is used for your business, and so are real estate taxes on business property, according to the IRS. The principal you repay is not interest, and limits can apply, so ask a tax adviser.
What tax rate should I enter?
Use your combined federal and state business rate. Enter zero to leave out the estimated saving.
Why is my lender's payment different?
Lenders may hold a cushion, size the deposits differently, use daily interest or add other reserves. Use this figure to plan and the quote for the real payment.
Does it include a balloon payment?
No. It assumes the loan is paid off over the term you enter. For a loan that matures sooner, use the commercial loan balloon payment calculator.
