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.

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 future value column shows what the note will grow to. If you give it a competing cash-sale price, it shows what the lump sum would grow to at the same reinvestment rate, side by side. The difference is the actual dollar premium of taking terms instead of cash.
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.
