Free Small Business Calculators
Quick browser-based calculators for makers and small sellers. Nothing you type into these calculators is uploaded or saved.
Which calculator should you use?
Start with the handmade product profit calculator when you are deciding whether a selling price actually covers materials, labor, packaging, shipping and seller fees. Use the craft fair calculator when the question is whether a market, pop-up or fair was worthwhile after booth, travel and payment-processing costs. Use the reorder point calculator when stock timing is the problem and you need a simple estimate based on average daily demand, supplier lead time and safety stock.
These tools deliberately solve narrow questions so you can get an answer without creating an account or configuring software. For a useful comparison, enter figures that reflect your normal operation rather than an unusually strong or weak day. Revisit the calculation whenever supplier prices, selling prices, fees, lead times or demand patterns change. The results are planning estimates, not accounting, tax, legal or financial advice.
Need a reusable operating system?
The free calculators answer one question at a time. The paid TAZERIS workbooks combine pricing, inventory, reorder planning, batch profit and summaries in editable files. They are intended for sellers who need to keep the underlying data, update it regularly and compare decisions over time rather than calculate one scenario and forget it.
