The service
Compound Interest Tool provides free financial calculators and explanatory content. The tools apply the inputs and assumptions stated on each page. We may correct errors, change a model or remove a tool when necessary.
Educational information, not personal advice
The site helps you explore scenarios. It does not recommend financial products, assess your circumstances or provide individual investment, banking, tax or legal advice. Projected returns are assumptions, not guarantees. Actual outcomes can differ because prices, rates, fees, taxes, timing and product rules change.
Using the results
Check the inputs and each page's assumptions before relying on an output. Do not use the site in a way that interferes with its availability, security or other users. You may link to public pages.
Before public launch
The site owner is Francisco Almeida, based in Lisbon, Portugal. Public contact details, the effective date and the applicable governing-law notice will be added before launch. Nothing in the final terms will limit consumer rights that cannot lawfully be excluded.
