Worked example for Johannesburg

Enter ZAR 10,000 as today's cost, 4.55% as the inflation rate and 10 years. If prices in Johannesburg kept rising at that pace, the same basket would cost ZAR 15,604 in 2036, and ZAR 10,000 left in cash would buy only what ZAR 6,409 buys now. The figure of ZAR 10,000 is just an example amount in South African rand; type your own rent, school fee or grocery bill instead.

The average of the ten calendar-year rates from 2016 to 2025 for South Africa works out at 4.9%. Try that figure as well as the latest 4.55% reading: the gap between the two shows how sensitive a long-range plan in Johannesburg is to which rate you pick. For a 20-year horizon the difference between 4.9% and 4.55% changes the future cost of ZAR 10,000 from ZAR 25,825 to ZAR 24,349.
