Freedom Number Calculator: How much do you need to retire in South Africa?
What's your freedom number?
Your freedom number is the amount you'd need invested to pay yourself the monthly income you want, for the rest of your life, without a salary. Put in two numbers and see yours in today's money.
There's no wrong number to be sitting on today. You just can't aim for one you've never seen.
How the freedom number is worked out
Multiply the monthly income you'd need by 12 to get a yearly figure. Then take 15 off the age you'd start living off your money and divide by 1,000. That gives you the share of your money you'd draw each year. Divide the yearly figure by that share and you have your freedom number.
At 55 the share is 4%, which lines up with the widely used 4% rule. At 60 it's 4.5%, and at 65 it's 5%. So someone who'd need R30,000 a month from 60 needs R360,000 a year, divided by 4.5%, which is R8,000,000.
How much do you need to retire at 50, 55, 60 or 65?
For R30,000 a month in today's money, you'd need about R10.3 million invested from 50, R9 million from 55, R8 million from 60 and R7.2 million from 65. The earlier you stop, the more years your money has to cover. That means taking a smaller slice each year, and a smaller slice needs a bigger pot.
| Start at | Drawn each year | Times yearly income | Freedom number |
|---|---|---|---|
| 40 | 2.5% | 40 | R14,400,000 |
| 50 | 3.5% | 28.6 | R10,285,714 |
| 55 | 4% | 25 | R9,000,000 |
| 60 | 4.5% | 22.2 | R8,000,000 |
| 65 | 5% | 20 | R7,200,000 |
Some people would rather work a few more years for a smaller target. Some would rather aim higher and stop sooner. This is your call. The calculator just shows you what each choice asks of you.
What the number includes, and what it leaves out
It's in today's money
Enter the income in today's rand and the answer comes out in today's rand too, so you can compare it with what you have now.
The income is before tax
What you draw from a retirement annuity or pension fund once you stop working is taxed like a salary, so enter the before-tax amount.
What counts towards it
Anything invested that you could live off: retirement annuities, pension or provident funds, tax-free savings, unit trusts. Not the home you live in.
It's a rule of thumb
It doesn't know your fees, how your money is invested or what markets will do. It gives you a clear target to plan around.

Freedom number questions
What is a freedom number?
Your freedom number is the amount you'd need invested to pay yourself the monthly income you want, for the rest of your life, without a salary. It's worked out in today's money.
How do I calculate my freedom number?
Multiply the monthly income you'd need by 12, then divide by (your age minus 15) divided by 1,000. For R30,000 a month from age 60: R30,000 × 12 = R360,000, and (60 − 15) ÷ 1,000 = 4.5%, so R360,000 ÷ 4.5% = R8,000,000.
How much do I need to retire in South Africa?
It depends on the income you want and the age you'd start living off your money. Using the freedom number formula, R30,000 a month in today's money needs about R8 million invested from age 60, or about R7.2 million from 65. Put your own numbers into the calculator above to see yours.
Is this the same as the 4% rule?
At 55 it is. The 4% rule uses the same share for everyone. This version changes it with age: less than 4% a year if you start living off your money before 55, and more if you start after, because your money has fewer years to cover.
Does the freedom number account for inflation?
Yes, by working in today's money. Enter the income you'd need at today's prices and the freedom number is also in today's rand, so you can compare it with what you have now.
Is this financial advice?
No. This calculator is financial education, a way to see a target clearly. For advice on your own situation, speak to a licensed financial adviser.
A number you can plan around
Once you've seen your number, you can make intentional moves towards it instead of guessing. Try a few ages and incomes and see which target feels like yours.
