About Interest Calculator

We build free, accurate interest calculators specifically for UK users, updated with current Bank of England data.

What We Do

interestcalculator.io provides a focused suite of interest calculators designed around UK financial products and rates. Unlike broad calculator sites, every tool here is built with UK tax rules, rate structures, and financial products in mind.

Our Data

Interest rates displayed on this site are sourced from the Bank of England Interactive Analytical Database (IADB) and updated automatically on a weekly basis. Rates shown are indicative averages and may differ from rates offered by individual providers.

Important Disclaimer

The calculators on this site are for illustrative and educational purposes only. They do not constitute financial advice. Results are estimates based on the inputs you provide and the assumptions stated on each calculator page.

We are not regulated by the Financial Conduct Authority (FCA). For personalised financial advice, please consult a qualified, FCA-regulated financial adviser.
