Frequently Asked Questions

Are these calculators really free?

Yes — all 26 calculators are completely free, with no signup, no email required, and no usage limits. They’re built by Tabby, an AI bookkeeping app for self-employed professionals, as a free resource for the communities it serves.

Who are these tools built for?

Self-employed professionals across six fields: consultants and coaches, real estate agents, contractors and home-service trades, personal-service providers like stylists and barbers, solo licensed professionals such as therapists and attorneys, and restaurant and food-truck operators.

How accurate are the results?

Each calculator uses standard industry formulas — margin-on-price bidding, fully burdened labor rates, net-proceeds math, and current tax rules. Results are estimates for planning purposes, not tax, legal, or financial advice; confirm significant decisions with a CPA or advisor.

Is my data saved or shared?

No. Every calculator runs entirely in your browser — the numbers you enter are never sent to a server, stored, or shared. Refreshing the page clears everything.

What is Tabby?
