FAQ
Are the calculators really free?
Yes. No sign-up, no email required, and they run entirely in your browser. Nothing you type is sent anywhere.
Who makes these?
Ledger Kits Express is a small California business that builds practical spreadsheets for landlords, hourly workers and freelancers. We cite the official source for every rule.
Is this legal or tax advice?
No. The tools apply published rules to the numbers you enter and give estimates. They are not a substitute for the advice of an attorney or tax professional, and we don't review your situation or fill in documents for you.
