How to Use the Calculator For Novated Lease for Accurate Takeoffs
Follow this four-phase operational workflow to compute verified jobsite material quantities, statutory tax withholdings, or official score benchmarks with exact tolerances.
Primary Input Parameters
Enter vehicle drive-away price in AUD ($) and selected lease term (1 to 5 years).
Regional Calibration
Select vehicle powertrain: Zero-Emission Electric Vehicle (EV/PHEV) or Internal Combustion Engine (ICE).
Live Computational Takeoff
Input gross annual salary to identify your top marginal tax bracket.
Verification & Export
Input estimated annual running costs (fuel/electricity, insurance, tires, maintenance).
Engineering Quality Standards & Tolerance Verification
When compiling professional estimates using this tool, engineers and analysts must apply standard variance allowances. For physical construction substrates, account for in-situ sub-base settling (typically 15% to 20% for bulk aggregate) and subgrade irregularities. For fiscal withholding and payroll calculations, confirm statutory year-to-date caps against active government schedules (IRS, HMRC, CRA, or ATO). All output models on BentoQuilt are calibrated continuously against current administrative statutes and industrial benchmarks.
Australian Novated Leases & The EV Electric Car Discount
A novated lease is a three-way agreement between an employee, their employer, and a fleet leasing company. It enables employees to finance a vehicle and pay for its operating running costs (fuel/charging, comprehensive insurance, servicing, and tyres) using a blend of pre-tax and post-tax salary deductions.
Under the Treasury Laws Amendment (Electric Car Discount) Act 2022, eligible battery electric vehicles (BEVs) and hydrogen fuel cell vehicles with a retail purchase price below the Luxury Car Tax (LCT) threshold for fuel-efficient vehicles ($89,332) are 100% exempt from Fringe Benefits Tax (FBT).
Why the EV FBT Exemption is so Lucrative
For a traditional petrol vehicle, an employee must utilize the Employee Contribution Method (ECM), paying roughly half of lease costs out of post-tax salary to offset FBT liability.
With an eligible EV under $89,332, 100% of the lease finance and 100% of all running costs are deducted from pre-tax salary. This shields your income from your top marginal tax rate (saving 30% to 47% including Medicare levy) while completely eliminating GST on the initial purchase price (saving up to $6,334).
