Can agents run this deterministically?

Yes. The `contractor_vs_employee` contract uses explicit numeric inputs and returns deterministic cost outputs.

Can I use this with AI agents too?

Yes. Some tools offer Quick Start and Advanced Controls when the calculator has real extra assumptions to unlock. Simpler tools stay single-mode, and the AI Integrations section points agents to the contract.

How to use it

Enter the W-2 annual salary, contractor hourly rate, annual hours, and the employer-side taxes, benefits, workers comp, and training or equipment costs. The goal is to compare the same workload on identical hours, not compare a full-time employee with a part-time contractor.
Read W-2 total annual cost, contractor annual cost, W-2 hidden costs, annual and monthly delta, cheaper option, and the break-even contractor hourly rate. If the contractor rate is above that break-even hourly number, the employee is cheaper strictly on cost.
Interpret the delta in context. When the contractor is only 5-10% more expensive, flexibility and variable commitment may justify the premium; when the contractor is 20% or more above the W-2 path for steady full-year work, the employee route usually wins financially.
Use the result to choose hiring structure, set approval thresholds, and anchor rate negotiations. Then layer in the non-calculator factors that matter just as much: ramp time, control, continuity, and classification risk.
Re-run when contractor rates, benefits, or expected annual hours change. Track the break-even hourly rate over time because wage inflation and benefit changes can move the crossover point faster than teams expect.

Agent FAQ

Should ChatGPT, Claude, or another agent click through the UI?

No. Start with /agent-tools.json, then follow the tool's contract URL. The page UI is for human review, not parameter discovery.

When do tools show Quick and Advanced?

Every tool opens in Quick Start first. Advanced Controls keeps the same scenario, reveals more assumptions or diagnostics, and every tool keeps AI integrations inline below the instructions.

When should an agent still open the browser page?

Open it when a human wants to sense-check the output, review the chart, or keep exploring related tools after the calculation finishes.

Questions people usually ask

What does this calculator compare?

It compares the same role as a W-2 employee versus a 1099 contractor and shows total annual cost for each option.

What hidden costs are included for W-2?

W-2 assumptions include employer FICA, FUTA, state unemployment, workers comp, health insurance, 401(k) match, and training/equipment.

How is break-even hourly rate calculated?

Break-even hourly rate is W-2 total annual cost divided by annual hours needed. Above that rate, W-2 is cheaper; below it, 1099 is cheaper.

Is this tool free and private?

Yes. AI Biz Hub tools are free, no-signup browser tools. Inputs stay in your browser unless you choose to share a URL.

Is this professional advice?

No. Outputs are business planning estimates only — not legal, tax, HR, or accounting advice.
