MyFinanceAtlas

Free Financial Calculators for South Africa, the UK, China, Japan & Singapore

MyFinanceAtlas provides free financial calculators tailored to different countries, currencies and financial systems. Pick your country and get loan instalments, mortgage payments, savings projections and tax estimates that follow the local rules — not generic formulas.

Choose Your Country

Every calculator is built for that country's currency, fees and regulations.

How the Calculators Work

Three steps, in your browser, with nothing sent to a server.

1. Enter your own numbers

You supply the amount, term and the rate your bank or issuer actually quotes. The calculators never assume a market rate.

2. See the maths instantly

Results recompute as you type — instalments, total interest and full year-by-year amortisation, with the formulas documented on our methodology page.

3. Adjust and compare

Stress-test a pessimistic rate, a bigger deposit or a shorter term before you talk to a lender — every input is yours to move.

Each country’s statutory rules are built into its calculators — NCA caps in South Africa, stamp duty bands in the UK, TDSR and MSR ceilings in Singapore. The full rule set behind every tool is documented on our methodology page.

Transparent mathematics

Every result shows its working — amortisation schedules, year-by-year breakdowns and the exact formulas on our methodology page. No black boxes.

Free, private, no signup

All calculators run entirely in your browser, work on mobile, and never ask for personal information. Educational estimates only — not financial, tax or legal advice.
