Compound Interest Planning for South African Savers

Compound interest grows your savings by earning returns on both your original deposits and previously earned interest. With monthly compounding, interest is added every month, so your balance can accelerate over longer periods. Regular monthly contributions can have an even bigger impact than trying to time markets, because consistency increases your invested base every month. This calculator helps you model realistic scenarios quickly so you can compare outcomes before making contribution decisions.

South African savers also need to consider tax efficiency. Tax-Free Savings Accounts (TFSAs) are popular for long-term goals because growth and withdrawals are generally tax-free when used within SARS contribution limits. The annual TFSA contribution cap is R36,000 and the lifetime limit is R500,000. Because excess contributions can trigger penalties, it is useful to track your annual and lifetime totals alongside projected growth. Use this tool as a planning guide and verify product-specific terms with your provider.

Frequently Asked Questions

What is the annual tax-free savings account limit in South Africa?

The annual contribution limit is R36,000 per tax year. Contributions above this limit can attract penalties from SARS.

What is the lifetime TFSA limit?

The current lifetime tax-free savings account contribution limit is R500,000 per person. Once you exceed it, SARS can apply a 40% penalty on the excess amount.

Do withdrawals reset my TFSA contribution room?

No. Withdrawals do not create new contribution room. If you withdraw funds, that amount still counts toward your lifetime R500,000 limit.

How does this compound interest calculator work?

It applies monthly compounding to your running balance and adds your monthly contribution each month, then shows invested capital, interest growth, and final value.
