About Toolnest

Toolnest is a directory of free online tools for business, marketing, finance and everyday tasks. Every tool works instantly in your browser — there's nothing to install and no account to create.

Free, always

Every calculator and generator on this site is free to use, with no usage limits and no paywalled features. The site is supported by advertising rather than subscriptions.

Estimates, not professional advice

Many of our tools — especially the finance calculators — provide simplified estimates based on the numbers you enter. They are not a substitute for professional financial, tax, legal or accounting advice. Tax rules in particular vary by country, region and personal circumstances and change frequently; where we don't model a specific jurisdiction's rules, we say so directly on the tool.

Before making an important financial, tax or legal decision, please verify the numbers with a qualified professional or an official source.

Privacy by default

Most of our tools run entirely client-side: your inputs are processed in your browser and are not sent to our servers. See our Privacy Policy for details.
