Free online finance calculators

This is your hub for free, easy-to-use financial calculators covering borrowing, saving, investing, budgeting, salary, and business pricing. Every tool supports pounds, dollars, and euros, runs instantly in your browser, and is built to be useful whether you are in the UK, the US, or elsewhere. Choose a calculator above to get started.

Plan, borrow, save and invest

Start with the budget calculator to understand your monthly money, then use the savings calculator to grow a surplus and the retirement calculator for the long term. Planning a big purchase? The loan & mortgage calculator shows the true cost of borrowing. Running a business? The profit margin calculator helps you price for profit.

A note on financial decisions

These tools give estimates to help you understand your options — they are not financial advice. For decisions that matter, especially around mortgages, investments, and pensions, consider speaking to a qualified, regulated financial adviser.
