Auto Loan Refinancing Savings Calculator

Implementation Specifications

This calculator is planned and documented. The formulas and guidance below are ready for implementation.

Current monthly = Balance × [r(1+r)^n] / [(1+r)^n - 1]

New monthly = Balance × [r_new(1+r_new)^n_new] / [(1+r_new)^n_new - 1]

Current total remaining = Current monthly × Remaining months

New total = (New monthly × New term) + Refinancing fees

Total savings = Current total - New total

Monthly savings = Current monthly - New monthly

Status: Specification complete, implementation pending

To implement: Create app/components/calculators/auto-loan-refinancing-savings-calculator.tsx and register in app/lib/calculator-registry.ts
