When to use this calculator

- When you want to see whether starting earlier or contributing more changes the outcome more.
A realistic South Africa planning example
Use these sample inputs as a quick scenario test, then change one variable at a time to compare outcomes.
| Input | Value |
|---|---|
| Initial Deposit (R) | R400,000 |
| Monthly Contribution (R) | R400,000 |
| Annual Interest Rate (%) | 5% |
| Years | 10 years |
After entering these figures, review final value, total deposited and interest together rather than in isolation. Then rerun the tool with one input adjusted.
How to read your results
Final Value
The figure produced by this output for the inputs you entered. Change one variable at a time if you want to see what drives it.
Total Deposited
The headline outcome of this calculation. It is most useful when read alongside the supporting metrics rather than in isolation.
Interest
The figure produced by this output for the inputs you entered. Change one variable at a time if you want to see what drives it.
Common mistakes
- !Using an assumption that is not supported by a current local quote, bill, statement or official source.
- !Treating a generic estimate as a lender, provider, payroll or tax authority decision.
- !Mixing monthly and annual inputs without converting them consistently.
- !Testing only one scenario instead of checking how a cautious assumption changes the result.
What to do next
- Run a second scenario with a cautious assumption so you can see the downside clearly.
- Compare the result with the related calculators below before making a decision.
- Check current local rules, eligibility and provider terms before applying or committing money.
- Keep a record of the assumptions so you can update the estimate when a quote, bill or pay figure changes.
Frequently asked
Fixed rate bonds typically pay 0.3-1.5% more than easy access, but lock in funds for 1-5 years with penalties for early withdrawal. They suit known future spending or part of a laddered strategy. Easy access wins for emergency reserves where liquidity matters.
