Free Business Finance Tools for Founders

Running a business means making financial decisions daily — often without a CFO in the room. BloaneCalc gives you the same calculations a financial professional would use, without the consulting fee. From negotiating a business loan to understanding your SaaS unit economics to filing payroll taxes correctly, the right calculation takes minutes and can save thousands.

Why These Tools Exist

Most free financial calculators are outdated, ugly, and don't use live data. BloaneCalc pulls real-time rates from the Federal Reserve, IRS, SEC, and currency markets — then presents them in a clean interface that respects your time. Built for US-based founders, freelancers, and small business owners who need accurate numbers fast.
