Clear calculations for everyday business decisions.

Calcavero is being built as a free collection of practical calculators for small business owners, ecommerce sellers, freelancers and marketers. Our aim is to make common business calculations easier to understand and quicker to complete.

What you will find here

Our tools cover profitability, pricing, advertising performance, ecommerce costs and other practical business questions. Each calculator is designed to explain its inputs, show the formula and make its assumptions visible.

How our calculators work

The calculators in this starter site run in your browser. You do not need to create an account, and the figures you enter are not sent to a calculator database by these tools.

Accuracy and limitations

Results are estimates based on the numbers you provide. They may not include every cost, tax, fee, or special circumstance relevant to your business. Always check the assumptions and consult an appropriately qualified professional when needed.
