Investments & Savings calculators

See how contributions, time and rate compound — then stress the growth assumption you just typed. Figures use the inputs you enter; they are not a local-tax or lender quote.

Start here, then explore the groups below.

Test the assumption, not a predicted return

Savings and investing calculators show how contribution, time and rate compound. They do not forecast markets. Run a cautious rate next to an optimistic one and keep fees in the same units as the growth rate.

  1. Fix the time horizon before you compare products or wrappers.
  2. Use the same contribution schedule in every scenario.
  3. Treat any growth rate as an input you chose — then stress it down.

Contribution, time, then rate

This hub brings together the investments tools currently available for ZA visitors. Start with the calculator closest to your question, enter figures that reflect your own situation, and compare more than one scenario when the decision is important.

The tools show the maths implied by the inputs. They do not replace provider quotes, professional advice, or country-specific rules that are not shown in the calculator. Review the assumptions beside each result before using it to make a decision.
