RunYourNumbers
Free, interactive calculators for everyday financial decisions.
RunYourNumbers is a free site for everyday money questions. How much will my savings grow? What will my bond repayment be? What will I actually take home after tax?
Each calculator is fast and simple. No sign-up. No spreadsheet. Just type in your numbers and get a clear answer.
The calculators use South African tax brackets and lending rules, so the answers match local conditions. Everything runs in your browser. There's no account, and nothing is saved on a server.
RunYourNumbers stays free because it's funded by ads, not subscriptions. The ads are placed so they stay out of your way while you use the calculators.
There's nothing to download and nothing to set up. Open the site, pick a calculator, and get your answer. It works the same way on a phone or a laptop.
New calculators get added over time, based on the money questions people actually ask. If you have one you'd like to see, you can suggest it through our contact page.
