## Summary

## FAQs (selected)

### Sales tax, trade-in, negative equity, fees?

Trade-in value and amount owed both matter. Tax and fees only inflate the loan when modeled as financed. State tax rate is user-entered.

### Credit score / subprime?

Four illustrative score ranges preset a note rate; edit freely to match a quote. No credit pull. Down payment can be zero.

### 72/84 months and early payoff?

Yes—terms and amortization plus extra principal modeling.

### How much car can I afford?

Use the reverse tool: https://financeflow.studio/car-affordability — [car-affordability.md](https://financeflow.studio/ai/car-affordability.md)

### Lease / refinance / specialty?

Lease not modeled. Refinance ≈ new rate/term on remaining balance. Classic/commercial = same math with realistic inputs.
