Frequently Asked Questions

Why is this not fixed at 3-6 months?

The model adapts target months based on household risk profile and deductible exposure.

What does job stability score do?

Lower stability raises recommended safety months to reduce layoff or volatility risk.

What if monthly savings is zero?

The tool flags that goals are not reachable without adding recurring savings capacity.

Can this work for variable-income households?

Yes. Use realistic average savings capacity and stress-test lower-bound months.

Can agents integrate this output?

Yes. emergency_fund is available with deterministic target and timeline fields.

Is this tool free and private to use?

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

Can I use this with AI agents too?

Yes. Human mode is the default experience. If you use AI automation, open the optional 'For AI Agents' section for deterministic contracts.
