Key takeaways
- In most transactions, all existing seller debt is paid off at closing from the sale proceeds. The seller receives net proceeds after debt retirement, not the headline price.
- A payoff letter is the lender's calculation of the exact amount required to pay off the loan on a specific date, including principal, accrued interest, and any prepayment penalties. It must be obtained before closing and is valid only for the specified payoff date.
- Prepayment penalties on term loans and SBA loans can range from 1% to 5% of the outstanding principal. On a $3M loan, a 3% prepayment penalty is $90K that comes directly out of the seller's proceeds.
- Revolving credit facilities typically have no prepayment penalty but require a formal payoff and termination of the facility at closing. Outstanding draws must be repaid.
- The net proceeds waterfall, the sequence in which sale proceeds are allocated, typically goes: debt payoff first, then transaction fees and taxes, then the seller's net cash.

When a founder models what they will receive from selling their business, they typically start with the purchase price and subtract estimated taxes. What many founders underestimate is the full cost of retiring existing debt at closing, including prepayment penalties, consent fees, and the mechanics of coordinating payoff with the lender on a specific closing date.
Every dollar of debt that is paid off at closing reduces the founder's net proceeds dollar for dollar. Understanding the debt payoff mechanics in advance allows the founder to model net proceeds accurately, negotiate the purchase price from a realistic baseline, and avoid closing-day surprises.
What the payoff letter covers
A payoff letter is the authoritative document from the lender that specifies exactly how much must be paid to retire the loan on a particular date. It is not the same as the current loan balance.
Components of a payoff letter
Outstanding principal
The current unpaid principal balance as of the payoff date.
Accrued and unpaid interest
Interest that has accrued since the last payment date. On a $2M loan at 7%, one day of accrued interest is $384. If closing is delayed by two weeks, the payoff amount increases by approximately $5,400.
Prepayment premium or penalty
A fee charged for paying off the loan before its scheduled maturity. SBA loans have a defined prepayment penalty schedule (5%/3%/1% in years 1/2/3). Conventional term loans may have make-whole provisions or step-down penalties.
Exit fees
Some lenders charge a flat exit fee, often 1–2% of the original loan amount, upon full repayment. Less common but present in some growth lending and mezzanine structures.
Lender's legal fees
Some lenders require the borrower to pay the lender's legal fees associated with releasing the UCC liens and security interests at closing. Typically $2,000–$8,000.
Per diem interest rate
The daily accrual rate, allowing the closing agent to calculate the exact payoff if closing occurs on a date other than the date specified in the letter.
Payoff letters are typically valid for 30 days. If closing is delayed beyond the validity date, a new payoff letter must be obtained. Coordinate with the lender on the expected closing date and request the letter for that specific date, not earlier.
Lender consent and UCC lien releases
Most commercial loans are secured by a UCC financing statement that creates a lien on the company's assets. That lien must be released at or before closing so the buyer receives the assets free and clear.
Some loan agreements also include consent requirements: the borrower must obtain the lender's consent before selling the business. Change of control provisions are common in term loans, revolving credit facilities, and SBA loans. A sale without the required consent is a technical default.
Lender consent timeline for a sale process
Day 1 (pre-signing)
Review all loan agreements for change of control provisions and consent requirements. Identify which lenders must be notified and when.
4–6 weeks before closing
Provide formal written notice to lenders of the pending transaction. Request a payoff letter for the anticipated closing date.
2–3 weeks before closing
Confirm lender consent has been granted or waived. Request UCC lien termination statements to be prepared for delivery at closing.
Closing day
Lender receives wire for payoff amount. Lender delivers UCC termination statements and a lien release letter. Title company or closing attorney confirms all liens are released.
Some lenders charge a consent fee for approving a change of control: typically $5,000–$25,000 depending on the lender and loan size. SBA lenders are required to approve sales of businesses with outstanding SBA loans, and the process can take three to six weeks. SBA payoff timing is a known closing risk that should be identified and started early in the sale process.

Schedule a conversation →The net proceeds waterfall
The net proceeds waterfall is the sequence in which the purchase price is allocated at closing. Understanding the waterfall prevents the surprise of receiving significantly less than the headline price.
Gross purchase price
$15,000,000
Less: seller debt payoff (principal + penalties + fees)
($2,850,000)
Less: banker fee (5% of transaction value)
($750,000)
Less: seller legal fees
($180,000)
Less: seller accounting/QoE fees
($120,000)
Less: escrow holdback (10% for 18 months)
($1,500,000)
Gross cash to seller at close
$9,600,000
Less: estimated federal and state capital gains tax
($2,160,000)
Net after-tax proceeds at close (estimated)
$7,440,000
In this example, a $15M headline price delivers $7.4M of after-tax net proceeds at close, with $1.5M held in escrow for 18 months. The founder who modeled only "what's a $15M business worth to me" and thought the answer was $15M would be surprised by the outcome.
The full waterfall analysis should be modeled before the founder sets a minimum acceptable price in the sale process. The right floor is the minimum net after-tax proceeds at close, not the minimum headline price. Working backward from an after-tax liquidity goal produces a more accurate minimum acceptable price than any rule of thumb about multiples.
How to minimize debt payoff costs before a sale
Founders who anticipate a sale in the next 12–18 months should review their debt agreements for prepayment penalty schedules and plan payoff timing accordingly.
Debt prepayment optimization before a sale
SBA 7(a) loans (taken within 36 months)
Prepayment penalty of 5% (year 1), 3% (year 2), 1% (year 3), then none. If an SBA loan was taken three years ago, waiting past the third anniversary eliminates the penalty.
Conventional term loans with step-down penalties
Review the schedule. A loan with a 3%/2%/1% step-down at years 3/4/5 may have crossed a step-down threshold recently. Confirm the current penalty before assuming the worst case.
Mezzanine and growth debt
Often have make-whole provisions that calculate the present value of all future interest payments the lender will not receive due to early repayment. These can be significant. Understand the calculation before closing.
Revolving credit facility
Typically no prepayment penalty on drawn amounts. However, terminating the facility may trigger an unused commitment fee or facility termination fee. Check the credit agreement.
