This retirement calculator for South Africa helps you to answer one question: am I saving enough? Enter your age, current savings, monthly contributions and assumptions to estimate your retirement fund, your likely monthly income, and any shortfall against a target income.
You can also switch between “today’s Rands” (inflation-adjusted) and future Rands to make the results easier to interpret.
How this retirement calculator works
The calculator projects your retirement fund by compounding your current savings and monthly contributions over time. It then estimates a “sustainable” monthly income using your chosen drawdown rate.
What “am I saving enough?” really means
Most people need to replace a portion of their salary in retirement. A common planning benchmark is a replacement ratio of around 75%, but your number depends on debt, dependants, medical costs, and lifestyle.
Key inputs that change your result
- Investment return: Even a 1–2% change makes a big difference over decades.
- Inflation: Inflation reduces buying power. “Today’s Rands” helps you compare apples with apples.
- Drawdown rate: A higher drawdown increases income now but raises the risk of your money running out.
- Contribution increases: If your contributions rise each year, your outlook can improve quickly.
Practical ways to close the gap
- Increase your monthly contribution and increase it annually.
- Retire later (even a few years can help).
- Lower your target replacement ratio if your costs will drop.
- Stress-test with a lower return and a lower drawdown for safety.
FAQ: Retirement calculator for South Africans
What is a good replacement ratio for retirement in South Africa?
Many retirement plans use a target of around 75% of pre-retirement income. However, your target should reflect your real expenses.
What drawdown rate should I use?
A lower drawdown is usually safer for long-term sustainability. Living annuities also have regulated drawdown ranges, so check your product rules.
Should I look at results in today’s rands or future rands?
Today’s rands are inflation-adjusted, which makes the numbers easier to understand. Future rands show the raw projected amounts at retirement.
Does the calculator include fees and tax?
No. Fees, tax, and product rules can materially change outcomes. Use this as a guide, then confirm numbers with your provider or adviser.
Why does a small change in return or inflation change everything?
Because compounding works over decades. Small annual differences compound into large changes by retirement.
