Start with a real question
“How many units cover my fixed costs?” Use Break-Even to separate your per-unit contribution from your monthly overhead.
“Is my markup the same as my margin?” Use Price & Margin to compare them and include percentage selling fees.
“What needs my attention today?” Open Focusboard, choose three priorities, and export a backup when you finish.
Calculators show estimates from your inputs and stated assumptions. They are planning tools, not personalized professional advice. Calculator inputs stay in your browser; export a CSV to keep results. Focusboard is a beta that saves on this device only and supports JSON backups.
