Worked example

Take a desired annual income of N12,000,000, lasting 25 years in retirement, with an expected return of 26% and inflation of 23%. What matters is the real return, the return after inflation, found by dividing one plus 26% by one plus 23% and subtracting one, which is about 2.4% a year. The corpus needed is the present value of an income stream of N12,000,000 a year for 25 years, discounted at that 2.4% real return. That works out to about N222,642,383, or roughly 18.6 times the annual income. The multiple is high because the real return is small: when your return only just clears inflation, the pot has to be large enough to fund almost the full spending each year without much help from growth.

How it is calculated

The tool treats your retirement as a stream of annual withdrawals and works out the lump sum that funds them. It first converts your expected return and inflation into a real return, dividing one plus the return by one plus inflation and subtracting one, which is the correct way to remove inflation rather than simply subtracting it. It then takes the present value of an annuity that pays your desired income for the chosen number of years, discounted at that real return: income times one minus the quantity one plus the real return raised to the negative number of years, all over the real return. The real return is what drives the answer. If your return only modestly beats inflation, the required corpus is close to your annual spending times the number of years. If your return actually trails inflation, the real return turns negative and the required corpus balloons, which is the honest warning that an investment mix that cannot beat Nigerian inflation makes retirement very expensive to fund.

Frequently asked questions

How much do I need to retire in Nigeria?
A useful starting point is the lump sum that, drawn down over your retirement years, funds your target annual spending while still earning a return. This tool uses a real return, your expected return less inflation, and the present value of an annuity. Because Nigerian inflation is high, the real return is what matters: if your return barely beats inflation, the pot you need is close to your annual spending times the number of years.
What is a realistic retirement income target in Nigeria?
That depends on your lifestyle and location, but a common planning approach is to replace 60 to 80 percent of your pre-retirement income. Enter the naira amount you expect to spend each year and the number of years you plan to draw it, then let the tool compute the corpus. A retiree in Lagos needing NGN 12,000,000 a year for 25 years requires a much larger pot than one in a lower-cost city with half that budget.
How does Nigerian inflation affect the retirement corpus calculation?
Inflation reduces the buying power of a fixed naira withdrawal each year. This tool incorporates inflation by converting your expected return and inflation into a real return before sizing the corpus, so the figure shown already reflects inflation-adjusted purchasing power. When your return is only slightly above inflation, the real return is small and the required corpus balloons, accurately capturing how expensive retirement becomes when investments barely keep pace with rising prices.
How does this calculator differ from the FIRE calculator?
The FIRE calculator uses the 4% rule, meaning a corpus of 25 times annual spending that in theory lasts indefinitely. This retirement corpus calculator uses the present value of an annuity approach, which models a pot that funds spending for a fixed number of years and then runs to zero. For a 25-year retirement the two methods give similar results at typical real returns, but the annuity approach makes the time horizon explicit and is useful for anyone who does not plan to leave money to heirs.
