car salary packaging calculator

What is car salary packaging?

Car salary packaging is a way to pay for a vehicle and related running costs using pre-tax salary. In Australia, this is often done via a novated lease. Instead of paying all car costs from your after-tax income, your employer deducts agreed amounts from your salary and pays those expenses on your behalf.

The main reason people look at salary packaging is potential tax efficiency. If some of your car costs are paid before income tax, your taxable income may reduce. The trade-off is Fringe Benefits Tax (FBT), which can offset or even remove the benefit depending on vehicle value, tax bracket, and contribution method.

How this calculator works

This calculator provides a practical estimate rather than a formal tax determination. It models two scenarios:

• Without salary packaging: you pay lease and running costs from after-tax income.
• With salary packaging: lease and running costs are treated as salary sacrifice amounts, then adjusted for possible GST credits, post-tax employee contributions, and estimated FBT.

It then compares annual take-home pay between those scenarios and shows an estimated net benefit (or cost).

Important assumptions used

• FBT taxable value uses the statutory formula: base value × 20% × days/365.
• Estimated FBT uses an effective factor of 0.8868 on net taxable value (approximation for common type 2 treatment).
• If EV exemption is selected, FBT is assumed to be zero.
• GST credit estimate is simplified as 1/11 of packaged expenses when selected.

Understanding each input

1) Salary and tax rate

Enter your gross annual salary and marginal tax rate. The calculator also includes Medicare levy to estimate your combined effective tax rate. If your tax position is complex (HECS/HELP, MLS, deductions, offsets), use this as an indicative result only.

2) Lease and running costs

Include annual finance/lease payments plus fuel, maintenance, insurance, tyres, registration, and other recurring vehicle costs. Use realistic yearly totals.

3) Base value and FBT inputs

The car base value drives the statutory FBT value. If the vehicle is available for private use all year, use 365 days. If not, reduce days accordingly.

4) Employee contribution method (ECM)

A post-tax contribution can reduce FBT exposure. Higher ECM often lowers FBT but also reduces your cash take-home directly, so the optimal value depends on your full arrangement.

When car salary packaging may work well

• You are in a higher marginal tax bracket.
• Your employer and provider fees are competitive.
• You have predictable annual kilometres and costs.
• You are eligible for EV FBT exemption.
• You plan to keep the arrangement for the intended lease term.

Common pitfalls to watch

• Ignoring fees: management, lease admin, and refinancing fees can erode savings.
• Underestimating FBT: small changes in taxable value can materially affect outcomes.
• Changing jobs: novated arrangements can require transfer, payout, or renegotiation.
• Cash-flow mismatch: savings on paper may still feel tight month-to-month.
• Residual risk: balloon/residual obligations matter at lease end.

Quick example

Suppose you earn $95,000, package $18,500 of annual vehicle costs, and face an effective tax rate around 34.5%. The pre-tax treatment may generate meaningful tax savings, but the final result depends heavily on FBT and any post-tax contributions. In many cases, ECM and EV eligibility become the two biggest levers.

Final note

This tool is designed for education and planning. Before signing any novated lease or salary packaging agreement, ask your employer/provider for a full quote, including all fees, residual value, FBT treatment, and assumptions. For personal advice, consult a qualified tax adviser or financial professional.
