About the numbers

  • Currency rates are daily mid-market rates from ExchangeRate-API. Banks and card providers add their own margin.
  • Projections (retirement, inflation, CAGR) assume steady rates. Real returns and inflation vary from year to year.
  • Tax rates for GST and VAT are standard rates; reduced and special rates apply to some goods and services.

These calculators are for information and planning. They are not financial, tax or investment advice.

Frequently asked questions

Are these calculators financial advice?

No. They do the math on the numbers you enter and are meant for planning and comparison. For decisions about investments, taxes or loans, check with a qualified adviser or your lender.

Is my financial information stored?

No. Everything except the currency rates runs in your browser, and nothing you enter is sent to a server or saved.

Which currency symbols can I use?

Every calculator has a currency selector (USD, EUR, GBP, INR, PKR, JPY/CNY, AED or none). Your choice is remembered on this device.
