About the toolkit

Know what belongs
in the budget.

Business Cost Kit helps U.S. small-business owners put the less obvious costs of a decision next to the obvious ones.

The first tool focuses on hiring. A salary offer is easy to compare. Employer taxes, insurance, benefits, and setup purchases take more work to assemble. The employee cost calculator gives those expenses a shared place in your budget.

What you can expect

Each calculator explains its inputs, shows a breakdown, and identifies costs it cannot determine. Estimates stay labeled as estimates. A blank state-tax amount is an unanswered question, not evidence that no tax applies.

We link to the official sources used for federal parameters and record the review date. The methodology explains the model’s limits so you can decide whether it fits your situation.

How the site is funded

Display advertising is the planned source of revenue. Ads are currently disabled, so no ad spaces appear. The calculator and PDF reports are free to use.

Scope before scale

Only working calculators are listed. There are no placeholder tools or state-specific pages built around unverified rates. This site provides budget estimates; it does not prepare payroll, determine legal obligations, or provide individualized tax advice.
