How This Calculator Works
Enter your current RA value, the return you expect, and the years to retirement. The calculator compounds the balance and shows the projected value and the growth. A retirement annuity is a personal retirement fund: contributions are deductible from taxable income (within limits), the investments grow free of income, dividends and capital-gains tax, and the proceeds are accessed from age 55.
The Formula
Future Value of a Lump Sum
PV = present value, r = annual rate, n = number of years
Worked Example
A R100,000 retirement annuity growing at 9% for 20 years reaches about R560,441 — roughly R460,441 of growth. A retirement annuity (RA) is South Africa's main personal retirement-savings vehicle, ideal for the self-employed or anyone topping up a workplace fund. Contributions are tax-deductible up to 27.5% of the greater of taxable income or remuneration, capped at R350,000 a year; the fund grows completely free of tax on interest, dividends and capital gains; and you can access it from age 55, taking up to a third as a lump sum (taxed on a favourable scale) with the rest providing a pension income.
Key Insight
The retirement annuity is the most tax-efficient way for individuals to save for retirement in South Africa, and its three-stage tax treatment drives the benefit. Going in: contributions are deductible up to 27.5% of the greater of your taxable income or remuneration, subject to an annual ceiling of R350,000 — so contributing reduces your income tax now, at your marginal rate, which is the biggest lever. While invested: the RA pays no tax on interest, dividends or capital gains, so returns compound untaxed (a meaningful edge over a discretionary investment that's taxed annually). Coming out: you can access the RA from age 55; you may take up to one-third as a cash lump sum (taxed on the retirement lump-sum table, with an initial tax-free portion), and the remaining two-thirds must purchase a pension income (a living or guaranteed annuity), which is then taxed as income. RAs are governed by Regulation 28, which limits how much can go into any one asset class (e.g. equities and offshore assets are capped) to enforce diversification — this constrains the achievable return and is why the assumed rate should be realistic. Other features: RAs are protected from creditors, can't be accessed early except on emigration (after a lock-up) or disability, and the recent 'two-pot' retirement reform changed how new contributions split between a preservation pot and an accessible savings pot. This calculator models a single existing amount compounding at a constant rate with no further contributions and omits fees, the contribution deduction (which boosts your effective return) and the eventual tax on the lump sum/income; in practice add your annual deductible contributions, keep fees low, respect Regulation 28, and plan the at-retirement split for tax efficiency.
Frequently Asked Questions
How is retirement annuity growth calculated?
Compound the value at the expected return over the years: value = amount × (1 + rate)^years. R100,000 at 9% for 20 years grows to about R560,441, roughly R460,441 of growth. This models a single lump sum with no further contributions, before fees and tax on withdrawal.
What is a retirement annuity?
South Africa's main personal retirement-savings product (RA) — ideal for the self-employed or topping up a workplace fund. Contributions are tax-deductible within limits, the fund grows free of tax on interest, dividends and capital gains, and you access it from age 55 as a part lump sum plus a pension income.
What's the tax benefit of an RA?
Three stages: contributions are deductible up to 27.5% of the greater of taxable income or remuneration (capped at R350,000/year), cutting your tax now; growth inside the fund is completely tax-free; and at retirement a portion of the lump sum is tax-free with the rest taxed on a favourable scale. This calculator omits the deduction, so your real return is higher.
When can I access a retirement annuity?
From age 55. At retirement you may take up to one-third as a cash lump sum (taxed on the retirement lump-sum table with an initial tax-free amount), and the remaining two-thirds must buy a pension income, taxed as income. Early access is generally only on emigration (after a lock-up) or disability.
What is Regulation 28?
A rule limiting how much an RA can hold in any one asset class — for instance caps on equities and offshore assets — to enforce diversification and manage risk. It constrains the achievable return, so use a realistic growth rate. The recent 'two-pot' reform also changed how new contributions split between preservation and accessible savings.

Methodology & Review
The future value compounds a retirement annuity lump sum at the annual return over the years, compounded annually. It assumes a single starting amount with no further contributions and a constant return, and does not model fees, the tax deduction on contributions, Regulation 28 limits, or the tax on the eventual income/lump sum.
