LeaseIQ Pro gives AI agents an exact, deterministic calculation engine for lease finance. LLMs cannot reliably do compounding interest, iterative solvers, or amortization by hand; this server does, with results regression-tested against Excel-verified values to the penny.

Commercial equipment finance tools

calculate_lease: exact periodic payment for equipment leases and finance agreements. Supports level payments, balloon, step-up/step-down, custom payment streams, interest-only periods, and skip/seasonal structures. Returns payment, tax, interim rent, and totals.
solve_lease_structure: Newton-Raphson reverse solver. Given a target payment, solves for the implicit interest rate (yield) buried in a quote, the term, the residual value, or the present value of a payment stream. Answers "what rate am I really paying?"
generate_amortization_schedule: complete period-by-period schedule (payment, interest, principal, balance) for any structure, with 30/360 or Actual/365 day counts.

Consumer auto tools

calculate_auto_lease: real captive-lender lease math with money factor rent charge, residual depreciation, state tax methods (monthly, upfront, TAVT), fee capitalization, zero-drive-off iteration, and multiple security deposit (MSD) discounts with ROI. Accepts a money factor or an APR.
calculate_auto_loan: exact loan payment, total interest, total cost, and upfront cash, for lease-versus-buy comparisons.

All tools return normalized inputs alongside results so agents can verify what was calculated, and validation errors are instructional: they name the field, what was provided, and the accepted range so agents can self-correct in one retry.
