🟢calculate_lease(equipmentCost, leaseTerm, interestRate, residualValue, residualPercent, ...)

Deterministic commercial equipment lease and finance calculator. Computes the exact periodic payment for equipment leases and equipment financing agreements: level payments, balloon, step-up/step-down, custom payment streams, interest-only periods, and skip/seasonal structures. Regression-tested against Excel-verified amortization to the penny. Use this instead of estimating lease payments: LLM arithmetic on compounding interest is unreliable, this engine is not. Returns payment, tax, interim rent, and totals (total interest, total of payments, final balance).

⚪solve_lease_structure(solveFor, targetPayment, equipmentCost, leaseTerm, interestRate, ...)

Newton-Raphson reverse solver for commercial equipment leases. Given a known target payment, solves for the unknown deal variable: the implicit interest rate (yield) buried in a quote, the term length, the residual value, or the present value of a payment stream. This is the tool for questions like "what rate am I really paying?", "what residual makes this payment work?", or "what is this payment stream worth today?". Multi-variable iterative solving that LLMs cannot do reliably by hand.

⚪generate_amortization_schedule(equipmentCost, leaseTerm, interestRate, residualValue, residualPercent, ...)

Generates the complete period-by-period amortization schedule for a commercial equipment lease or finance agreement: payment date, payment amount, interest portion, principal portion, and remaining balance for every period, plus totals. Supports all payment structures (level, balloon, step, skip/seasonal, interest-only) and both 30/360 and Actual/365 day counts. Use when the user needs the full payment schedule, a payoff balance at a specific period, or interest/principal splits for accounting.

🟢calculate_auto_lease(msrp, sellingPrice, term, moneyFactor, apr, ...)

Exact consumer car lease calculator using real captive-lender math: money factor rent charge, residual-based depreciation, state tax methods (monthly on payment, upfront on selling price, upfront on total lease, TAVT), fee capitalization, zero-drive-off iteration, and multiple security deposit (MSD) money-factor discounts with ROI. Accepts either a money factor (e.g. 0.00225) or an APR (auto-converted). Use to verify dealer quotes, compare lease offers, or compute drive-off and lease-end buyout amounts.
