View yearly breakdown+
Retirement planning is mostly about time. This calculator projects how investing a share of your income every month, year after year, could build a naira portfolio by the age you plan to retire — and shows the yearly path so you can see the effect of compounding.
What this retirement calculator does
It takes your age, monthly income, the share you invest, your target retirement age, and an expected return, then projects the portfolio you could accumulate by retirement, year by year.
Because the horizon is long — often decades — small changes to the contribution rate or return compound into very large differences at the end. The yearly breakdown makes that visible.
How it is calculated
Each year you invest your monthly amount twelve times, and the whole portfolio earns the expected return. Contributions made early have the most years to compound, so they do the heaviest lifting in the final figure.
The longer the gap between your current age and retirement age, the larger the share of the final portfolio that comes from growth rather than the cash you put in — the essence of compounding.
A worked example
A 35-year-old earning ₦1,000,000 a month who invests 20% (₦200,000 monthly) at a growth-oriented return until age 65 has 30 years of compounding. The total contributed is ₦200,000 × 12 × 30 = ₦72,000,000, but the projected portfolio ends up far larger because returns compound on top of every contribution for decades.
Start the same plan ten years later, at 45, and the final figure drops sharply — not because you contributed much less, but because you removed ten of the most powerful compounding years. Starting early beats contributing more later.
How to read your result
Look at both the final portfolio and the yearly curve. The steepening shape near the end shows compounding doing most of the work — which is why interrupting contributions early is so costly.
The projection is in nominal naira. Convert the final figure to today's money with the inflation calculator so your retirement target reflects real buying power, not just a large headline number.

Frequently asked questions
When should I start saving for retirement in Nigeria?+
As early as possible. Because returns compound over decades, the years you save in your 20s and 30s contribute far more to the final portfolio than the same amounts saved in your 50s. Starting early usually beats contributing more later.
How much of my income should I invest for retirement?+
A common starting point is 10–20% of income, but the right figure depends on your target and horizon. Use the calculator to test different shares and see which one reaches your goal.
Does this replace my pension (RSA) contributions?+
No. Treat this as a planning estimate for total retirement saving. Your formal pension (Retirement Savings Account) contributions can be part of the picture; this tool helps you see whether the overall plan is on track.
Is the retirement calculator free?+
Yes. It runs in your browser, needs no sign-up, and stores none of your inputs.
