Free Business & Calculators

Invoices and barcodes, loan and VAT calculators, percentages and age.

What these business & calculators are for

The everyday tools of running a small business or a household budget: a professional PDF invoice in a minute, barcodes for products, the true monthly cost of a loan with a full repayment schedule, VAT added or taken off correctly, and quick percentage and date maths.

Everything is calculated in your browser, so your figures and client details are not sent anywhere.

Questions

Can I use the invoice generator for my business?
Yes. It produces a clean PDF with your details, line items, tax and totals, free and without a watermark or account.
How do I remove VAT from a price?
Divide by one plus the rate - for 20% VAT, divide by 1.2. Taking 20% off the gross price is a common mistake and gives the wrong answer; the VAT calculator does it correctly.
Is my data stored?
No. The calculators and generators run in your browser and nothing you enter is sent to us.
