Formula Used
This calculator applies present value mathematics to the payments you want to sell.
Per-period discount rate = Annual discount rate / Payments per year
Per-period growth rate = Annual growth rate / Payments per year
Payment at period t = Payment × (1 + growth rate per period)t - 1
Present value at period t = Payment at period t / (1 + discount rate per period)n
For an ordinary annuity, n = t. For an annuity due, n = t - 1.
Gross present value = Sum of all discounted sold payments
Net lump sum = Gross present value - Company fee - Estimated tax withholding
Haircut = 1 - (Gross present value / Nominal value of sold payments)

Sell Annuity Payments: Math Behind the Estimate
Why present value matters
Selling annuity payments means trading future cash for cash today. The trade is never equal on a simple face-value basis. Buyers discount future payments because time has value. Risk also matters. Administration costs matter too. That is why the lump sum offer is lower than the total of all future checks.
This sell annuity payments calculator uses present value mathematics. It converts each future payment into a value in today’s money. Then it adds the discounted values together. That total becomes the estimated gross offer. After that, fees and tax withholding can be deducted to estimate the net amount you may actually receive.
Inputs that change the payout
The periodic payment amount is the base driver. Bigger payments usually create a bigger lump sum. Payment frequency also changes the result. Monthly, quarterly, and annual schedules discount differently. The number of years remaining matters because longer timelines place more cash farther into the future.
The discount rate is critical. A higher rate reduces present value faster. Small rate changes can create large differences in the final offer. Growth rate is also important for increasing annuities. If payments rise over time, later checks can add more value. Fees and taxes then reduce the amount you keep.
Full sale versus partial sale
A full sale transfers the entire remaining stream. A partial sale transfers only a selected number of payments. Partial sales can help you solve a short-term need while still keeping future income. This calculator shows both the sold value and the retained value. That comparison supports better decision making.
Use the estimate wisely
This tool is strong for planning. It helps compare scenarios quickly. You can test different discount rates, fee levels, and sale sizes. You can also review the payment schedule and the cumulative present value graph. Use the math to ask sharper questions, compare offers, and understand the real cost of selling annuity income.
FAQs
1. What does this calculator estimate?
It estimates the current lump sum value of the annuity payments you want to sell. It also shows fees, estimated tax withholding, retained value, and a discounted payment schedule.
2. Why is the lump sum lower than total payments?
Future payments are discounted to today’s value. Buyers also build in profit, risk, and processing costs. Because of that, the present value is lower than the nominal total.
3. What is an ordinary annuity?
An ordinary annuity pays at the end of each period. That means every payment is discounted for at least one full period in the calculation.
4. What is an annuity due?
An annuity due pays at the beginning of each period. The first payment is discounted less, so its present value is usually higher than the same ordinary annuity payment.
5. Can I model a partial sale?
Yes. Enter the number of payments you want to sell. The calculator values only that portion and also estimates the value of payments you keep.
6. How important is the discount rate?
It is one of the biggest drivers. Even a small change in discount rate can significantly raise or lower the present value and your estimated net proceeds.
7. Are fees and taxes exact?
No. They are planning inputs. Actual fees, legal costs, transfer charges, and taxes depend on the buyer, your contract, and local rules.
8. Why include inflation?
Inflation helps you judge the real discount rate. It adds context by showing how much purchasing power may be lost while waiting for future payments.
