Retirement Annuity Calculator

How the Retirement Annuity Calculator Works

A retirement annuity (RA) is a private retirement savings vehicle regulated by the Pension Funds Act. Contributions are tax-deductible up to 27.5% of the greater of your taxable income or remuneration, capped at R350 000 per tax year across all retirement fund contributions. Growth inside the fund is tax-free - no CGT on capital gains, no tax on interest or dividends within the fund.

The calculator projects the future value of your RA using a compound growth formula: it takes your current fund value plus regular monthly contributions and grows them at your selected annual return rate over the years until retirement. The formula used is:

Where P is the current fund balance, r is the monthly growth rate, n is the number of months to retirement, and PMT is the monthly contribution.

The tax saving is calculated by comparing your annual tax liability with and without the RA deduction. The difference represents the genuine annual tax saving - real rand value returned to you by SARS for choosing to invest in an RA. This saving effectively reduces your net cost of contributing.

How to Use This Calculator

1. 1

   Enter your current RA balance

   Log in to your RA provider's portal (Allan Gray, Coronation, Sanlam, Discovery, etc.) and find your current fund value. If you are starting a new RA, enter zero.

2. 2

   Set your monthly contribution

   Enter the amount you contribute or plan to contribute each month. Remember the 27.5% of taxable income / R350 000 annual cap - the calculator will warn you if your contribution exceeds the deductible limit.

3. 3

   Set years to retirement and expected return

   South African balanced unit trust funds have historically returned 10–13% per year over long periods. A conservative assumption is 8–10%. Use a lower rate for a more prudent projection - the difference over 20–30 years is dramatic due to compounding.

4. 4

   Enter your annual salary

   Your salary is used to calculate the marginal tax rate at which your RA deduction is worth the most. The higher your marginal rate, the greater the tax saving per rand contributed.

5. 5

   Review the tax saving and net cost

   The net monthly cost of your RA contribution is the contribution minus the monthly tax saving. At a 36% marginal rate, a R2 000/month contribution costs you only R1 280 after the tax saving - SARS effectively funds R720 of it.

Frequently Asked Questions

How much can I deduct for retirement annuity contributions in South Africa?

SARS allows a deduction of up to 27.5% of the greater of your taxable income or remuneration, subject to a maximum of R350 000 per year across all retirement fund contributions (pension fund, provident fund, and RA combined). Contributions above this limit are not lost - they carry forward to future years and can be deducted then, or are excluded from tax when you take your retirement lump sum.

When can I access my retirement annuity in South Africa?

You can access your RA from age 55 (the minimum retirement age). Upon retirement, you may take up to one third as a tax-free lump sum (up to the applicable threshold), and the remainder must be used to purchase a living annuity or life annuity to provide a regular income. Early access before 55 is generally not permitted, except on emigration via the SARB formal emigration process or in cases of ill health.

What is a living annuity vs a life annuity in South Africa?

A life annuity (guaranteed annuity) pays a fixed monthly income for the rest of your life - the insurer carries the longevity risk. A living annuity invests your capital and lets you draw an income of 2.5–17.5% per year; you carry the risk that the capital runs out. Most South Africans choose living annuities for the flexibility, but they require active management to avoid depleting the capital before death.

Is growth inside an RA taxable in South Africa?

No. Growth within a retirement annuity fund is entirely tax-free: no CGT on capital gains, no income tax on interest, and no dividends tax on dividends earned within the fund. This tax-free compounding is one of the primary advantages of an RA versus an ordinary discretionary investment account, where each of these events is taxable.

What happens to my RA if I die before retiring?

On death, the trustees of the fund have discretion to distribute the proceeds among dependants and nominated beneficiaries. Unlike ordinary investments, your RA does not automatically form part of your estate and is therefore not subject to estate duty or executor's fees - a meaningful estate-planning benefit. Dependants (spouse, minor children) generally receive priority over nominated beneficiaries.

Can I have both a pension/provident fund and an RA?

Yes. Many South Africans contribute to an employer-sponsored pension or provident fund and also run a personal RA for additional retirement savings or to top up after a period of self-employment. The 27.5% / R350 000 deduction cap applies to the combined total of all retirement fund contributions across all funds.
