Free calculators for small business

The everyday sums, without a signup wall in front of them.

Each of these runs entirely in your browser — nothing you type is sent anywhere. The figures you enter go into the page's URL, so you can bookmark a calculation or send it to your accountant and they will see exactly what you saw.

Calculators

GST calculator Add or remove 10% GST from any amount, and see the GST-exclusive, GST and GST-inclusive figures at once.
Hourly rate calculator Work back from the income you want to the hourly rate you need to charge, after costs, leave and tax.

Working out a GST figure by hand? The short version: to add GST, multiply by 1.1. To find the GST inside a total that already includes it, divide by 11. The GST calculator does both and shows all three figures at once.

Keep your books for nothing
