How to use the calculator
Enter your payments, the lump sum you could get, and a yearly return you might earn on it after fees. The calculator grows the balance at that return and takes out each payment when it would have arrived.
If the money runs out before the last payment, the lump sum would not have replaced the income the payments provide. Try a lower return too: investment returns are never certain, while scheduled payments are set in advance.
Lump sum or payments: what to weigh
Payments give steady, predictable income, often for many years. A lump sum gives flexibility now, for example to pay off high-interest debt or cover a large expense, but it has to be managed and can be spent quickly.
Selling payments is usually expensive, because buyers apply a discount rate. Alternatives include selling only part of your payments, keeping them and budgeting, or other forms of financing. A fee-only financial adviser can help you compare these for your situation.
