How LeaseLens works

We use AI to read your lease document, extract every financial figure, and give you an honest, independent assessment of whether you're getting a fair deal.

The Process
1

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.

2

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
3

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:

๐Ÿ“ How the IRR calculation works

We solve for the monthly interest rate r in the following equation:

Principal = Payment ร— [(1 โˆ’ (1+r)^โˆ’n) / 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 โˆ’ 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.

4

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 (8โ€“12% p.a.)
  • Standard car loan rates for EVs (~5.5โ€“7% 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.

5

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.

6

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.

โš  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.

Privacy & Security
๐Ÿ”’

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.

๐Ÿข

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.

Frequently Asked Questions
What file types can I upload?โ†“
PDF files work best as they preserve the original formatting. PNG, JPG, and WEBP image files are also supported โ€” for example, if you've photographed your quote or taken a screenshot. You can upload multiple files at once if your quote spans several pages.
What if the interest rate isn't on my quote?โ†“
Many providers don't state the interest rate explicitly โ€” they just show you a monthly payment and a residual value. In this case, LeaseLens calculates the effective rate using the IRR (Internal Rate of Return) method from the principal, payments, residual, and term. This is clearly flagged in your results as an estimate. The accuracy depends on the figures being correctly read from the document.
How accurate is the analysis?โ†“
The analysis is typically very accurate when the document is clear and contains all the relevant figures. The mathematical calculations (IRR, effective rate) are precise given correct inputs. However, AI document reading is not infallible โ€” figures may occasionally be misread, particularly in low-quality images or complex formatting. Always cross-check key numbers against your original document. See our full disclaimer for more detail.
Does this work for all novated lease providers?โ†“
Yes โ€” LeaseLens works with any Australian novated lease provider including SG Fleet, FleetPartners, Maxxia, RemServ, Smartleasing, Eclipx, and others. It also works with employer in-house salary packaging arrangements. As long as the quote contains the key financial figures, the analysis will work.
Is this financial advice?โ†“
No. LeaseLens provides general information and analysis only. It does not constitute financial, tax, or legal advice. Your personal tax situation, employer arrangements, and financial circumstances significantly affect the true cost of a novated lease and cannot be fully accounted for by this tool. Please consult a licensed financial adviser before making any decisions. Read our full disclaimer for complete details.
Is the service free?โ†“
Yes, LeaseLens is currently free to use. No account or credit card required.
