About MoneyMzansi

Last updated 9 November 2026

MoneyMzansi is a free set of money calculators for South Africans. It helps you check a salary offer, plan a bond, grow your savings or work out car finance, using the official figures for the 2026/27 tax year.

Who runs it

MoneyMzansi is run independently by the MoneyMzansi team. We are not a bank, a financial services provider or part of any financial group, and no company pays us to show its products. The site is free to use and has no sign-up.

Where the figures come from

Every tax rate, rebate, limit and threshold comes from the South African Revenue Service (SARS), mostly from its published rates for individuals and its tax-free investment rules. The prime lending rate follows the repo rate set by the South African Reserve Bank (SARB). Where a figure is published by someone other than SARS, we cross-check it against SARS before we use it.

Each calculator page lists its sources at the bottom, along with the date the figures were last checked. The current figures cover the tax year from 1 March 2026 – 28 February 2027 and were last checked on 9 November 2026.

How often we update them

• After every Reserve Bank interest rate decision, which happens about every two months.
• After the Budget Speech each February, when new tax tables, rebates and limits are announced.
• On 1 March each year, when the new tax year starts.

We also re-read every guide and check every source link at least twice a year.

How the calculators work

Every sum runs in your own browser. Nothing you type is sent to us or stored anywhere. If you use a share link, the link itself carries the numbers you chose to share, and nothing else. Each calculator comes with a plain-English guide that explains the maths, with a worked example produced by the same code that runs the calculator.

What the calculators can’t do

The results are estimates to help you plan. They are not financial, tax or legal advice, and they can’t take every detail of your situation into account. Before you sign anything or make a big decision, check with SARS, your bank or a licensed financial adviser. Read our disclaimer for the full details.

How we keep the lights on

Right now the site carries no adverts and no paid links. In future we may show clearly labelled adverts or sponsored links to keep the site free. They will never change a calculator’s results. Our affiliate disclosure explains how that would work, and our privacy policy explains what data we do and don’t collect.
