Stop paying high fees, and make Future You more money

Higher fees very likely means lower returns (and here's the maths to prove it)

Paying high fees on your retirement investments (such as a retirement annuity or a living annuity) almost always means less money in your pocket, and less money for your retirement. Read more

Higher fees very likely means lower returns (and here's the maths to prove it)
  • Monthly contribution: R4,000
  • TFSA lifetime limit: R500,000
  • Investment term: 30 years
  • Annual return: 12%
  • Annual inflation: 6%

The contributions will stop after reaching the limit, but the money will stay invested for the full 30 years. The returns are compounded monthly and adjusted for inflation to determine the final investment values.

Example 1 (1%): After 30 years, the final investment value is approximately R1,438,627

Example 2 (3%): After 30 years, the final investment value is approximately R901,248

Always make sure you understand your Effective Annual Cost (EAC). This will be shown on your statement or you can request it from your service provider. EAC is a standardised metric that was introduced by ASISA. All else being equal, a higher EAC would mean that less of your investment returns can be reinvested and potentially grow and compound over time.

At 10X, we keep our fees low, so that more of your money is invested for you. If you've got investments elsewhere, you can use our EAC calculator to compare service provider fees with 10X.
