Commercial Real Estate Loan Payoff Calculator: Months to Zero Out
See how long a commercial real estate loan takes to pay off at a fixed monthly payment, and the total interest paid across the payoff. For balloon loans, the payoff month signals the balloon date and required refinancing.

How This Calculator Works
Enter the current loan balance, the loan rate, and the fixed monthly payment. The calculator simulates interest and payments month by month and counts the months until the balance reaches zero. Commercial loans often run shorter balloon terms (5 to 10 years) with longer amortization (20 to 25 years) — the calculator's payoff date is full amortization, not balloon date.
The Formula
Debt Payoff Time
B = balance, P = fixed monthly payment, r = monthly rate (APR ÷ 12), n = months to clear
Worked Example
A $1,000,000 commercial real estate loan at 7% APR paid down at $10,000/month clears in 151 months — about 12.6 years — with roughly $505,000 of interest along the way. Most commercial loans, however, have 5- or 10-year balloon dates; at year 10, the remaining balance ($455,000) would need to be refinanced or paid off in full.
Key Insight
Commercial real estate loan payoff math is dominated by the balloon structure rather than full amortization. A 25-year-amortization loan with a 10-year balloon means making 10 years of payments based on the 25-year schedule, then owing a large remaining balance — usually requiring refinance into a new loan at then-current rates. Refinancing risk is the biggest hidden risk: if rates have risen, the new loan payment is dramatically higher even though the balance has been paid down for 10 years.

Frequently Asked Questions
How does commercial real estate payoff math differ from residential?
Commercial loans typically use balloon structures — payments based on 20-to-25-year amortization, but the full remaining balance due at year 5 or 10. Residential mortgages typically fully amortize over 30 years with no balloon. The 'payoff date' for commercial usually means refinance, not full payoff.
What's a typical commercial loan rate?
Commercial loans typically price at 10-year Treasury + 2.0% to 3.5% spread, currently 6% to 8.5%. Multifamily and Class A office trade at narrower spreads; retail and hotels at wider. Recourse loans cost less than non-recourse (CMBS) loans typically.
What is refinancing risk?
When the balloon comes due, you must refinance into a new loan at current rates. If rates have risen substantially (as in 2022-2024), the new loan payment can be 50%+ higher on the same balance — sometimes more than the property can support, forcing distressed sale.
Should I extra-pay to avoid balloon stress?
Some commercial lenders prohibit prepayment (yield maintenance, prepayment penalties) — read the loan documents. Where allowed, accelerated payment reduces the balloon balance and refinancing risk, though it ties up capital that might earn more elsewhere.
What if I can't refinance at the balloon?
Options: extend with the current lender (sometimes available, usually at higher rate), sell the property to pay off the balloon, take CMBS or bridge financing (higher rate but available), or default. Refinance market conditions at the balloon date matter enormously.
When is this calculator unreliable?
Less reliable when prepayment penalties — yield maintenance / defeasance can be 5-20% of balance, when balloon structures (most CRE has 5-10 yr balloon vs 25 yr amort), when interest-only periods, when variable rate + SOFR-tied loans, when tax depreciation cost recovery + 1031 exchange, when cash-flow vs DSCR covenants, or when commercial vs SBA 504 / 7(a) differences.

Methodology & Review
Commercial real estate loan payoff = remaining principal with accelerated payments. U.S. 2024: CRE loans 5-25 yr amortization with 5-10 yr balloon common; APR 6-12%; prepayment penalties (yield maintenance, defeasance, step-down) substantial; refinance + 1031 exchange impact payoff strategy. RELIABILITY: Reliable for vanilla amortization. Less reliable for (a) prepayment penalties — yield maintenance / defeasance can be 5-20% of balance, (b) balloon structures (most CRE has 5-10 yr balloon vs 25 yr amort), (c) interest-only periods, (d) variable rate + SOFR-tied loans, (e) tax depreciation cost recovery + 1031 exchange, (f) cash-flow vs DSCR covenants, (g) commercial vs SBA 504 / 7(a) differences.
