What is DigiTool Shed?

DigiTool Shed is a free library of single-purpose online calculators and tools, built for people who need a quick, accurate answer without creating an account or digging through ads. Each tool focuses on one job — a fee calculator, a word checker, a size converter — and shows its math so you can see exactly how the result was reached.

The current lineup is built around online selling: Etsy, eBay, Shopify, Depop, Mercari, Poshmark, and PayPal fee calculators, plus cross-platform comparison tools for sellers deciding where to list. A second set of word and game tools — anagram solvers, dice rollers, score counters — covers game night. New categories are added as they're built, not promised in advance.

Every calculator is free to use, requires no signup, and is rebuilt whenever a platform changes its fee structure so the numbers stay current.
