Seller Finance Future Value Calculator

Lump sum now or payments over time? See what a stream of seller-financed payments will grow to if reinvested as they come in, plus any balloon, and compare it side by side with what an equivalent lump sum would grow to over the same horizon.

What you can realistically earn reinvesting each payment as received.

Seller financing ends up larger at the same reinvestment rate. Note that this ignores default risk. Both sides count everything the seller collects, so the down payment sits on the financing side; the headline above is the note by itself.

About This Seller Finance Future Value Calculator

When a buyer asks the seller to carry the financing, the seller's first instinct is usually 'I'd rather just have the cash.' That instinct ignores something important: a seller-financed note produces a stream of money over years, and every dollar received can be reinvested. The future value of that reinvested stream — plus a balloon if there is one — is what the seller actually ends up with at the end of the note. Compared to taking a lump sum today and reinvesting it at the same rate, the seller-financed deal is often the larger pile of money, especially when the note rate beats what the lump sum would earn elsewhere.

This calculator runs the math both ways. Enter the monthly payment your buyer is offering, the duration, your assumed reinvestment rate (whatever you believe you can earn on the payments as they come in — could be Treasuries, an index fund, another note you'd buy), and any balloon. The headline shows what the note itself will grow to. If you give it a competing cash-sale price, it also asks for the down payment, because a cash offer is the seller's entire proceeds and the financed deal has to be counted the same way: note plus the cash at closing, which compounds from day one just as the lump sum does. Leave the down payment out and the comparison is rigged toward cash before it starts. The difference between the two totals is the actual dollar premium of taking terms.

The reinvestment rate represents what the seller can realistically earn on cash in hand — whether that's a lump sum or the monthly payments as they arrive. Money markets and short Treasuries set a low-risk floor, long-term equity returns sit higher with more risk, and rolling proceeds into more notes typically lands in between. The same rate applies to both sides of the comparison, so what shifts the result is timing: a lump sum compounds from day one, while seller-financed payments only start compounding once they've been received.

Future value is the inverse of net present value. If you want to know what a note is worth today (for selling it on the secondary market), use the free Note Appraisal Calculator — it estimates a market value directly from your note's risk characteristics. If you already have a target yield in mind and just want the discounting math, use the free Seller Finance NPV Calculator. If you want to model uneven cash flows, irregular timing, or compute IRR on a comparison, use the GoFlexi TVM calculator. This page is for the question: 'If I take terms and reinvest the income, how much money will I end up with?'

Frequently Asked Questions

What is future value in the context of a seller-financed note?

Future value is the total amount of money you'd accumulate by the end of the projection if every monthly payment were reinvested at a chosen rate, plus any balloon paid at the end. It's the answer to: if I take this deal, how much money will I have at the end? Future value is the natural counterpart to net present value — NPV looks backward to today, FV looks forward to the end of the duration.

What reinvestment rate should I use?

Use what you believe you can realistically earn on the payments as they come in. Money markets and short Treasuries set a low-risk floor; long-term stock-market returns sit higher with more risk; rolling the proceeds into more notes typically lands somewhere in between. The rate you choose has a big impact on the comparison — try a couple of values to see the range.

How do I compare cash now versus seller financing?

Run two future value calculations at the same reinvestment rate: one on the cash offer (lump sum compounded at the rate over the chosen duration) and one on the seller-financed deal — monthly payments reinvested, plus the balloon, plus the down payment compounded from closing. Counting the down payment matters more than it sounds: on a 20%-down deal it is often the single largest item on the financing side, and omitting it is the most common way this comparison gets quietly tilted toward cash. The larger result wins on a pure-math basis. This calculator shows both side by side. Note that this ignores risk: seller financing carries default risk that a cash sale doesn't, so the terms deal usually needs to win by enough to compensate.

Does seller financing always beat a cash sale on future value?

No. It depends on the relationship between the note's effective yield and your reinvestment rate. If the note is at 6% but you can reinvest at 9%, the cash sale typically wins. If the note is at 9% and you can only reinvest at 4%, the terms deal wins big. Beyond the math, terms come with non-financial tradeoffs — illiquidity and default risk on the downside, the tax advantage of spreading capital gains across the payment years on the upside — so the all-in comparison usually involves more than just future value.

How is this different from the seller-finance NPV calculator?

NPV asks: at this discount rate, what is the future cash stream worth in today's dollars? FV asks: at this reinvestment rate, what will the future cash stream grow to in tomorrow's dollars? Same inputs, opposite directions. Use NPV when valuing the note for sale today; use FV when comparing 'cash now versus terms' for your own retirement or wealth horizon.

Should I use my note's interest rate or my reinvestment rate?

Use the reinvestment rate. The note's interest rate is already built into the monthly payment you'd receive. The question this calculator answers is: once that payment is in your hands, what rate do you compound it at? That's a different number — usually lower, because you're investing in safe instruments rather than the property loan you originated.

Does this account for taxes?

No, this is a pre-tax projection. Seller financing has different tax treatment than a cash sale — installment sale treatment can spread capital gains across the years payments are received, which is often a tax advantage.

What if the note has an interest-only or balloon-only structure?

Those work fine in this calculator: enter the interest-only monthly payment in the Monthly Payment field, the balloon amount, and the duration. The calculator reinvests each interest-only payment as received and adds the balloon at the end. For more exotic structures (escalating rates, principal-only periods, ARM resets), use the full GoFlexi calculator.
