You upload your quote
Drop in your novated lease document โ PDF, photo, or screenshot. It can be a full salary sacrifice schedule, a quote summary page, or even just photos of the key pages. Multiple files are fine if your quote spans several pages.
Your document is sent securely and directly to the AI for analysis. It is never stored, logged, or retained by LeaseLens.
AI extracts the financial figures
The AI reads your document and extracts all the key financial variables, including:
- Total amount financed and vehicle price
- Monthly lease rental payments (pre and post-tax)
- Lease term and annual kilometres
- Residual / balloon value at end of term
- All included running costs (insurance, tyres, rego, servicing, charging)
- Management fees and any optional add-ons
- FBT method and employee contribution
- GST savings applied
The effective interest rate is calculated
This is the most important step โ and the one most lease providers make deliberately opaque.
If your quote states an interest rate, we verify it by calculating the true effective rate independently and checking for discrepancies. Some providers advertise a low rate but inflate fees elsewhere to compensate.
If your quote does not state an interest rate, we calculate it using the IRR (Internal Rate of Return) method โ the same methodology used by financial analysts:
๐ How the IRR calculation works
We solve for the monthly interest rate r in the following equation:
Principal = Payment ร [(1 โ (1+r)^โn) / r] + Residual / (1+r)^n
Where: Principal = total amount financed, Payment = monthly lease rental ex GST, n = number of payments, Residual = balloon value ex GST.
The monthly rate is then annualised: Annual rate = ((1+r)^12 โ 1) ร 100
This is the same method banks use to calculate comparison rates on loans. When the interest rate is estimated via IRR rather than read directly from the document, this will be clearly flagged in your results.
Your rate is compared to the market
We compare your effective rate against real-world benchmarks for the Australian market, including:
- Current novated lease market low (~7.0% p.a.)
- Typical novated lease range (8โ12% p.a.)
- Standard car loan rates for EVs (~5.5โ7% p.a.)
- Manufacturer or brand direct finance rates where applicable
This tells you not just what your rate is, but where it sits relative to what you could actually get elsewhere.
Your full cost picture is assembled
Novated leases bundle many costs together โ which makes it easy to miss overpriced components. We break out every line item: insurance, tyres, servicing, charging costs, management fees, and any optional add-ons.
For EVs, we calculate the value of the FBT exemption and show you the true after-tax monthly cost โ which is the only number that really matters when comparing options.
You get an honest verdict and action checklist
We score your deal out of 10 and provide a plain-English verdict. More importantly, we give you a specific action checklist โ things you can actually go back and negotiate on, such as vehicle pricing discrepancies, above-market insurance premiums, or unapplied manufacturer discounts.
We also show a comparison table against alternative finance options (car loan, direct finance, optimised novated) so you can see the full picture before deciding.
โ Important limitations to understand
LeaseLens is an AI-powered tool and its analysis is only as accurate as the information visible in your document. Tax savings estimates depend on your income, employer, and personal circumstances which we do not have access to. Interest rate calculations are mathematical estimates based on the figures extracted โ if any figure is misread or missing, the calculation will be affected. This tool provides general information only โ not financial advice. Always verify key figures with your lease provider and consult a licensed financial adviser before making decisions. Read our full disclaimer โ
Your documents are never stored
Your lease document is sent directly to the AI API for analysis and immediately discarded. LeaseLens does not store, log, or retain any documents, results, or personal information. There is no user account, no database, and no record of your analysis after you close the page.
We are completely independent
LeaseLens is not affiliated with, sponsored by, or partnered with any novated lease provider, salary packaging company, car dealer, or financial institution. We do not receive referral fees or commissions. Our only interest is giving you an accurate, unbiased analysis of your quote.
