Commercial Balloon Payment Calculator: Estimate Your Balance Due

If you’re facing a commercial balloon payment, you’re not alone. Many commercial real estate loans are structured with balloon payments that require borrowers to pay off the remaining principal balance in full at the end of the loan term—often catching business owners off guard when the bill comes due. (For a complete breakdown of how commercial balloon loans work and your options at maturity, see our Commercial Balloon Loans Guide.)

Our Commercial Balloon Payment Calculator helps you estimate exactly how much you’ll owe when your balloon payment matures, so you can plan ahead and explore your refinancing options before it’s too late.

What Is a Commercial Balloon Payment?

A balloon payment is a large, lump-sum payment due at the end of a commercial loan term. Unlike residential mortgages that typically fully amortize over 30 years, commercial loans often have shorter terms (5-10 years) but are amortized over longer periods (20-30 years).

For example, you might have a commercial mortgage with a 7-year term amortized over 25 years. You make monthly payments as if you’re paying off the loan over 25 years, but after 7 years, the entire remaining balance becomes due in one balloon payment.

Balloon Payment vs. Fully Amortizing Loan

Understanding the difference between a balloon loan and a fully amortizing loan is crucial when choosing commercial financing. Here’s a side-by-side comparison using a $2,000,000 loan at 6.5% interest:

Feature	Balloon Loan (5-Year Term, 25-Year Amort)	Fully Amortizing Loan (25-Year Term)
Monthly Payment	$13,513	$13,513
Balance After 5 Years	$1,821,447 (balloon payment due)	$1,821,447 (continues amortizing)
Total Interest Paid (5 Years)	$389,327	$389,327
Total Interest Paid (Full Term)	Depends on refinance terms	$2,053,900 (over 25 years)
Pros	Lower initial rate, flexibility to refinance, matches shorter hold periods	No refinance risk, predictable payments, no balloon payment surprise
Cons	Refinance risk, rate risk at maturity, must qualify again in 5 years	Higher initial rate typically, less flexibility, longer commitment
Best For	Properties you plan to sell/refinance within 5-10 years, value-add deals	Long-term holds, stable cash flow properties, risk-averse borrowers

Notice that the monthly payments are identical for the first 5 years—the difference is what happens when the balloon loan matures. With a balloon structure, you’ll need to either refinance, sell the property, or pay off the $1.8+ million balance in cash.

Why Balloon Payments Catch Borrowers Off Guard

The most common reason balloon payments surprise borrowers is simple: it doesn’t feel like you still owe that much. You’ve been making substantial monthly payments for years, so it’s natural to assume you’ve made significant progress paying down the loan.

But here’s the reality of loan amortization: early payments are heavily weighted toward interest, not principal. In the example above, your $13,513 monthly payment in month 1 breaks down to roughly $10,833 in interest and only $2,680 in principal. Even by month 60 (year 5), you’re still paying about $9,867 in interest and $3,646 in principal per payment.

This is because interest is calculated on the outstanding balance, and in the early years, that balance remains high. Take a $2 million commercial bridge loan at 6.5%:

• Month 12: Payment #12 = $2,698 principal + $10,815 interest
• Month 60: Payment #60 = $3,646 principal + $9,867 interest

After 5 years of payments totaling over $810,000, you’ve only reduced the principal by $178,553—less than 9% of the original loan amount. The rest went to interest. This amortization curve is why balloon payments feel like a shock: mentally, you’ve been “paying the mortgage” for years, but mathematically, you’ve barely scratched the surface of the principal balance.

Add in rising interest rates, tighter lending standards, or a property that hasn’t appreciated as expected, and that balloon payment can become a serious financial challenge rather than a routine refinance.

What to Do When Your Balloon Payment Is Coming Due

If your balloon payment is coming due within the next 12-24 months, you have several options. Here’s what most commercial borrowers consider:

1. Refinance the Balloon Loan

This is the most common solution. You take out a new commercial mortgage to pay off the balloon balance, ideally locking in favorable terms for another 5-10 years. Start the process 6-9 months before maturity—commercial underwriting takes longer than residential, and you’ll want time to shop rates. Be prepared for a new appraisal, updated financials, and potentially different loan-to-value requirements. If your property’s DSCR has improved since your original loan, you may qualify for better terms.

2. Sell the Property

If you were planning to exit the investment anyway, timing the sale to coincide with your balloon maturity can make sense. This works best for value-add investors who’ve stabilized a property and are ready to cash out. Factor in 90-180 days for a commercial sale, and remember that broker fees, closing costs, and capital gains taxes will reduce your net proceeds. If market conditions are soft, a forced sale to meet your balloon deadline can put you in a weak negotiating position.

3. Pay Off the Balance in Cash

If you have sufficient liquid reserves or the property has generated strong cash flow, paying off the balloon in full eliminates debt and gives you unencumbered ownership. This option is most common with smaller balloon balances (under $500K) or when borrowers want to simplify their holdings before retirement. Best for: high-net-worth borrowers with diversified portfolios who don’t want to carry commercial debt or go through the refinance process again.

4. Negotiate a Loan Extension

Some lenders will extend your existing loan for 1-3 years, giving you more time to refinance or sell. This usually comes with an extension fee (0.5-1% of the balance), a rate adjustment, and stricter terms. Start conversations 4-6 months before maturity—waiting until the last minute weakens your negotiating leverage. Extensions work best if your payment history is spotless and the property still meets the lender’s underwriting criteria, but rates are temporarily unfavorable for a full refinance.

Frequently Asked Questions

How do I calculate a balloon payment?

To calculate a balloon payment, you need to know: (1) your original loan amount, (2) your interest rate, (3) your amortization period, and (4) your loan term. Calculate the monthly payment as if you’re paying off the loan over the full amortization period, then determine how much principal you’ll pay down during the shorter loan term. The balloon payment is the remaining balance at the end of the term. Our calculator above does this math for you automatically.

Can I refinance my balloon loan before it’s due?

Yes, and it’s often a smart move. Refinancing 6-12 months early gives you time to shop for the best rates and terms without the pressure of an imminent deadline. However, check your current loan for prepayment penalties—some commercial loans charge 1-5% of the balance if you pay off the loan early. If market rates are lower than your current rate, the savings from refinancing may outweigh the penalty.

What happens if I can’t pay my balloon payment?

If you can’t pay your balloon payment and can’t refinance, the lender can foreclose on the property. This is why it’s critical to start planning at least 12 months before your balloon maturity date. If you’re facing challenges (property value declined, income issues, credit problems), talk to your lender early—many will work with you on an extension or modification rather than going straight to foreclosure.

Are balloon payments common in commercial real estate?

Yes, balloon payments are the norm in commercial real estate lending. Most commercial mortgages have terms of 5-10 years with longer amortization periods (20-30 years), resulting in a balloon payment. Lenders prefer this structure because it limits their long-term risk and allows them to reassess the loan and adjust rates every few years. Borrowers benefit from lower monthly payments than a fully amortizing loan would require over the same term.

Should I refinance my balloon loan early or wait until maturity?

The answer depends on your current rate, market conditions, and prepayment penalties. Refinance early if: (1) current rates are significantly lower than your existing rate (0.5%+ savings), (2) your prepayment penalty is minimal or has expired, (3) your property has appreciated or your DSCR has improved, giving you better refinance terms, or (4) you want to lock in certainty rather than gamble on rates 6-12 months from now. Wait until closer to maturity if: (1) you have a steep prepayment penalty (3-5%), (2) you expect rates to drop further, (3) you’re planning to sell within 12-18 months anyway, or (4) your current loan terms are already competitive and you’d rather avoid closing costs until necessary. Most borrowers find the sweet spot is starting the refinance process 6-9 months before maturity—early enough to avoid time pressure, late enough to minimize prepayment penalties and maximize property performance improvements.
