About Numbra

Numbra creates focused calculators and spreadsheet trackers for Etsy sellers, landlords, freelancers, and other independent operators.

Each download is designed around a specific recurring decision—from pricing a product to monitoring property cash flow—so you can spend less time building formulas and more time using the answer.

Products are delivered instantly and can be reused without a subscription. Every listing explains the file format, intended workflow, and what is included.
