Why can two equal principal amounts have different value?
A promise to pay $300,000 soon is economically different from a promise to pay the same amount several years later. During the wait, the seller gives up access to that cash and remains exposed to repayment risk. The valuation hub helps compare cash at closing, fixed future payments, and contingent proceeds as separate parts of an offer.
Present value is the value at a stated date of future cash flows discounted using a stated return assumption and payment timetable.A seller-note model should begin with the actual payment obligation. Distinguish a fixed note from an earnout tied to client collections or performance. The note may still face default risk, but its contractual amount is different from a formula whose payment changes with results. Combining the two under deferred proceeds obscures the seller’s exposure.
The IRS installment-sale publication explains tax issues involving installment payments, interest, and contingent arrangements within its scope. That guidance does not provide a universal market discount rate. Use it with a tax advisor while maintaining a separate economic comparison of the proposed cash flows.
What belongs in the payment schedule?
Record closing cash separately, then enter each principal and interest payment on its contractual date. Include payment holidays, interest accrual, variable-rate terms, amortization, and any final balloon. Identify whether unpaid interest is capitalized, paid later, or waived. A summary saying payable over six years cannot support precise arithmetic.
Confirm whether scheduled payments are permitted under senior-lender documents. A payment due under the note may be blocked by a subordination or standby arrangement. Show the controlling restriction and model the resulting cash timing. Do not interpret interest accruing during a restricted period as cash the seller can spend during that period.
Track other conditions that change cash flows, including permitted offsets, indemnity deductions, acceleration rights, and prepayment terms. Counsel should determine their legal operation. The valuation worksheet should show the assumptions used rather than silently treating every scheduled dollar as unconditional available cash.
How is the arithmetic calculated?
For a payment at the end of year t, divide the payment by one plus the annual discount rate raised to t. Add the discounted payments and any immediate cash. For monthly or irregular dates, use a consistent period convention or a dated-cash-flow method and state the convention alongside the result.
Assume, solely for illustration, a $300,000 principal obligation paid as six $50,000 year-end payments with no contractual interest. Compare it with a $300,000 principal balloon paid at the end of year six, also without interest. These structures are arithmetic examples, not recommendations or statements of permitted tax treatment.
| Assumed annual discount rate | Six annual $50,000 payments | One year-six $300,000 payment |
|---|---|---|
| 8% | $231,144 | $189,051 |
| 12% | $205,570 | $151,989 |
| 16% | $184,237 | $123,133 |
The inputs are deliberately hypothetical. They illustrate how later cash receives a larger timing discount under the same assumption. They do not establish an appropriate rate for an accounting practice, a fair value conclusion, or a lender-approved note. Adding contractual interest would change the cash-flow schedule and the resulting values.
Round only the final displayed result. If a model uses monthly dates, document whether a quoted annual rate is effective or nominal and how it is converted. Seemingly small convention differences can create confusion when the spreadsheet is attached to a negotiated term sheet. Both parties should be able to reproduce the calculation.
How should a discount assumption be selected?
State the purpose of the analysis: personal offer comparison, formal valuation, lender review, or another use. A qualified advisor may use different evidence and standards for different purposes. The valuation-date discussion explains why a rate and financial record should match the relevant measurement date.
Consider the borrower’s repayment capacity, collateral, senior debt, payment restrictions, and the seller’s concentration in the obligation. Do not assume that collateral eliminates loss. Identify what assets secure the note, their realizable value, lien priority, and enforcement costs. These facts inform the risk discussion even where the model presents only a sensitivity range.
The IRS publishes Applicable Federal Rates for federal tax purposes. Those prescribed rates are not a substitute for assessing an individual buyer’s credit risk or the seller’s economic required return. Have the tax advisor determine which tax rules apply and document that conclusion separately from the offer-comparison rate.
Avoid hiding all uncertainty in one percentage. A delayed payment scenario, reduced recovery scenario, and changing rate scenario explain different risks. If the model discounts an already reduced expected cash flow using a rate that also prices the same default risk, ask the valuation advisor whether the analysis is double-counting that exposure.
What makes a larger note a weaker offer?
A larger face amount can be offset by later payment, a fragile borrower, or a large refinancing-dependent balloon. A seller comparing offers should look at immediate usable cash, scheduled fixed payments, possible reductions, and security together. A single headline purchase price cannot show those differences.
For example, a buyer may offer more principal while requiring several years without cash payments. Another may offer less total principal but more at closing and shorter exposure. Calculate both schedules on the same date and assumptions, then show the risk differences outside the arithmetic. The model should help the seller ask better questions, not turn unlike obligations into falsely precise equivalents.
If the offer includes an earnout, use the earnout payment-timing guide for the variable component. Do not include maximum contingent proceeds in a fixed-note schedule as though they are assured. Show scenario payments and explain what performance or collections must occur for each one.
How do taxes and closing deductions affect the comparison?
The IRS business-sale guidance explains that an asset sale involves different assets with potentially different tax treatment. A note’s interest and principal also require separate analysis. The seller’s after-tax result depends on the actual structure, basis, allocation, and applicable rules, not just the note’s face amount.
Build a separate after-tax schedule with the tax advisor’s assumptions. Avoid subtracting one estimated tax bill from every offer when their payment timing and asset allocation differ. Clearly mark estimates, date them, and identify unresolved reporting issues. A pre-tax present-value comparison is useful but cannot promise spendable retirement proceeds.
Use the debt-payoff and net-proceeds guide to reconcile closing deductions. Existing debt payoff, transaction expenses, and holdbacks can reduce cash received immediately even when the price is unchanged. Keep the buyer’s future note payments distinct from money used to settle the seller’s obligations at closing.
What should the seller review before accepting a note?
Obtain the payment schedule, borrower financial evidence, lien and guarantee information, senior-lender restrictions, and draft note documents. Ask counsel and the tax advisor to review the actual structure. Record unresolved issues with the economic comparison rather than waiting until closing to discover that an assumed payment is restricted.
The completed decision record should show face principal, contractual interest, timing, modeled present value, risk scenarios, and immediate net cash. That gives the seller a basis for negotiating terms and identifying an acceptable exposure. It does not convert an uncertain promise into cash or replace a formal valuation when the transaction requires one.
A few common questions
What else should you know?
Is a seller note worth its stated principal amount?
Its contractual principal is one input, not the entire economic comparison. Payment timing, interest, creditworthiness, security, and restrictions affect the value to the seller. A present-value model makes timing assumptions visible, but it does not prove collectibility. Compare the model with the actual borrower and signed legal protections.
Should the note rate also be the discount rate?
Not automatically. The note rate determines contractual interest; the discount rate represents the economic return assumed for evaluating those payments. They answer different questions. Use a documented rationale and sensitivity range rather than selecting the contractual rate simply because it appears in the offer. Tax-rate rules also require separate review.
How should a balloon payment be modeled?
Place the balloon on its actual contractual date, along with any interest due. Then test whether the buyer can fund it through operating cash, refinancing, or another realistic source. A present-value calculation can quantify timing but cannot establish future refinancing availability. Show a delayed or impaired repayment case when that risk matters.
Can a present-value comparison replace legal diligence?
No. Review lien priority, guarantees, covenants, subordination, payment restrictions, default remedies, and governing documents with counsel. A spreadsheet assumes cash flows arrive according to its inputs. Legal diligence tests the seller’s rights when they do not. Keep unresolved protections visible instead of compensating for them with an unexplained discount percentage.
