Quick answer: You can calculate your commercial loan payment using the standard loan payment formula. For an amortizing loan, your payment depends on the loan amount and interest rate, with the amortization period also affecting the result. For an interest-only loan, multiply the principal by the annual interest rate, then divide that by 12 to estimate the monthly interest payment. Always check the loan term too, because you may owe a balloon payment at maturity if the loan term is shorter than the amortization period.

Choosing from among several commercial real estate loans can seem complicated:
One lender may offer a lower rate but a shorter term, while another may give you a longer amortization period or interest-only payments. But once you understand the numbers behind each offer, it’s much easier to see which loan costs you less over time.
Here’s how to calculate your commercial loan payment step by step, even if you don’t have a commercial mortgage calculator handy.
How do I calculate my commercial real estate loan payments?
Your loan officer can give you the basic numbers you’ll need to calculate your commercial loan payments.
Make sure it includes:
- Your principal
- Interest rate
- Amortization period
- Loan term
- Payment structure
From there, you’re ready to use the formula to find your monthly payment for a standard amortizing commercial real estate loan:
M = P × [r(1 + r)ⁿ] ÷ [(1 + r)ⁿ − 1]
Here’s what those letters mean:
- M = monthly principal-and-interest payment
- P = original loan amount
- r = monthly interest rate, or your annual rate divided by 12
- n = the total number of monthly payments in your amortization schedule
Say you have a 25-year amortization, which would normally mean 300 monthly payments.
If your loan starts with an interest-only period, your scheduled payments during that period won’t reduce the principal.
You can calculate the interest-only payment using this formula:
Monthly interest payment = Principal × annual interest rate ÷ 12
If you’re borrowing $2 million at 5.99% on an interest-only basis, your monthly interest payment would be:
$2,000,000 × 0.0599 ÷ 12 = $9,983.33
$9,983 is the amount you’ll pay in interest every month.
During a three-year interest-only period, your scheduled payments wouldn’t reduce the $2 million principal over those years. You’ll still owe $2 million at maturity, unless you made additional principal payments. From there, you may have to repay the balance or sell the property, or even find another repayment option.
The numbers change when you amortize the same loan.
If you take out a $2 million loan at 5.99% amortized over 25 years, your monthly principal-and-interest payment would be approximately $12,874.
| $2 Million Loan at 5.99% | Approx. Monthly Payment | Principal Reduction |
|---|---|---|
| Interest-Only | $9,983 | None through scheduled IO payments |
| 25-Year Amortization | $12,874 | Yes |
The amortizing loan requires a higher monthly payment because you’re paying interest and reducing your principal at the same time.
What does my monthly payment cover?
You need to understand where your money is actually going once you’ve worked out your monthly payment.
In an amortizing loan, you’re paying the principal and interest each month. Some of your payment brings down what you owe, while the rest goes toward interest.
An interest-only loan works differently because your regular monthly payments cover the interest but don’t pay down the principal during the interest-only period. While this helps lower your monthly payment, your loan balance generally stays the same unless you make extra payments toward the principal.
You should also check whether your loan has a balloon payment. If it does, you’ll need to pay the remaining balance when the loan reaches maturity. A balloon payment can arise when your loan term is shorter than your amortization period, which is common in commercial real estate financing.
What is the difference between ‘loan term’ and amortization period?
Your loan term tells you how long you have before the loan matures. At maturity, you need to deal with any outstanding balance.
On the other hand, your amortization period determines the repayment schedule used to calculate your monthly principal-and-interest payments.
For example, you could have a 10-year term with a 25-year amortization. In this arrangement, your lender calculates your monthly payments using a 25-year repayment schedule, even though the loan matures after 10 years.
So, when those 10 years are up, you’ll still have part of the loan left to pay. You’ll typically need to pay that remaining balance as a balloon payment or refinance it into a new loan.
A shorter amortization period means you’re paying off the loan faster, so you’ll usually have a higher monthly payment. The upside is that more of your principal gets paid down sooner.
Stretch the amortization over more years, and your monthly payment will generally come down. But because you’re paying the loan off more slowly, your principal balance also takes longer to decrease.
| Loan Structure | Monthly Payment | Principal Reduction | At Maturity |
|---|---|---|---|
| Shorter amortization | Higher | Faster | Less principal remains over the same period |
| Longer amortization | Lower | Slower | More principal remains over the same period |
| Term equals amortization | Based on full repayment | Scheduled to reduce balance to $0 | No scheduled balloon |
| Term shorter than amortization | Based on longer schedule | Partial repayment | Remaining balance comes due |
Consider a five-year term with a 25-year amortization, for example. You make monthly payments based on a 25-year schedule, but the loan matures after five years. At that point, you’ll generally need to pay or refinance the remaining balance.
Why should you pay attention to term and amortization?
Your term and amortization period can impact your property’s cash flow and what you’ll need to do when the loan matures.
With a longer amortization, you’ll typically get a lower monthly payment. This can leave you with more cash for things like repairs or other property expenses. On the other hand, you’ll pay more each month on a shorter amortization, but you can bring down your principal faster.
You also need to think about refinancing risk. If your loan ends with a balloon payment, you may plan to refinance when it matures. However, factors like interest rates and property values could change before then, along with market conditions.
What are the differences between interest-only bridge payments and fully amortizing loans?
It’s worth understanding how interest-only bridge payments and fully amortizing loans handle the principal differently.
| Factor | Interest-Only Bridge Loan | Fully Amortizing CRE Loan |
|---|---|---|
| Monthly Payment | Covers interest during the IO period | Covers principal and interest |
| Payment Amount | Usually lower | Usually higher |
| Principal | Generally remains unchanged without extra payments | Gradually decreases |
| Loan Structure | Often short-term | Typically longer repayment structure |
| Balloon Payment | Common | None if term matches full amortization |
| Cash Flow | Lower payments leave more cash available in the short term | Higher payments steadily reduce debt |
| Common Use | Acquisitions, renovations, repositioning or lease-up | Stabilized properties held longer term |
| Refinancing | May require refinancing or repayment at maturity | No scheduled balloon when fully amortized over the term |
Think back to the $2 million loan example earlier at 5.99%. With interest-only payments, you’d pay about $9,983 per month, but your scheduled payments wouldn’t reduce the $2 million principal. With a 25-year fully amortizing structure at the same rate, you’d pay about $12,874 per month, with some of each payment reducing your debt.
That difference can significantly affect your monthly cash flow and how much you’ll eventually need to repay.
How much will your commercial loan payments be?
The examples above can help you understand the math, but you still need to ask a lender for their specific terms to understand your actual commercial loan payment.
