Lease Rate Factor: Formula, Calculation & Examples

Updated 12 Mar 2026Content was accurate at the time of publication

What is the lease rate factor (money factor)?

The lease rate factor — often called the money factor — is the small decimal lessors use to calculate the finance charge portion of a lease payment. Instead of quoting an APR, many leasing providers show a value such as 0.00250. That decimal multiplied by the sum of the capitalised cost and the residual value determines the monthly finance charge.

Common formats include decimal form (money factor) such as 0.00250, and quoted equivalents sometimes labelled "MF", "money factor" or "rate" in lease documents.

For a plain-language definition, see the money factor glossary. If you're shopping for equipment, review the equipment leasing guide to understand broader lease structures.

How the lease rate factor works

The money factor is used only to calculate the finance (interest) portion of the monthly lease payment. The lease payment has two core parts:

Depreciation: recovery of the difference between the capitalised cost (what you effectively finance) and the residual value at lease end.
Finance charge: cost of funding, driven by the money factor.

The calculation flow works like this:

Lessor sets a capitalised cost (the negotiated price of the asset).
Lessor estimates a residual value (expected value at lease end).
Depreciation = (Capitalised cost − Residual) ÷ Term (months).
Finance charge = (Capitalised cost + Residual) × Money factor.
Monthly payment = Depreciation + Finance charge.

Because the finance charge uses (capitalised cost + residual), leases with higher residuals generally have lower monthly depreciation but a slightly higher finance charge base. That trade-off is central to comparing lease offers or deciding between a lease and a loan. For vehicle-specific lease structures, review related entries such as Finance Lease, Operating Lease and Novated Lease.

Formula: Basic lease payment calculation

Standard formulas used by lessors (monthly basis):

Depreciation portion:

\text{Depreciation} = \frac{\text{Capitalised cost} - \text{Residual value}}{\text{Term (months)}}

Finance charge:

\text{Finance charge} = (\text{Capitalised cost} + \text{Residual value}) \times \text{Money factor}

Total monthly payment:

\text{Monthly payment} = \text{Depreciation} + \text{Finance charge}

Annotated variables:

Capitalised cost: negotiated price plus any capitalised fees (sometimes called cap cost).
Residual value: pre-agreed estimated value at lease end (may be a percentage of MSRP).
Money factor: small decimal (e.g., 0.00250).
Term: months (e.g., 36).

When you read a lease quote, ensure the capitalised cost includes or excludes fees clearly — those affect the base. For end-of-term obligations, also review balloon payment and depreciation.

Convert money factor to APR (and back)

A commonly used quick conversion:

\text{Approximate APR (\%)} \approx \text{Money factor} \times 2400

This industry shortcut gives a rough annualised rate for comparison. It is widely used because money factor represents a monthly financing factor; multiplying by 2400 (12×100×2) is a practical approximation used by many brokers and dealers to compare with APRs. Use it for ballpark comparisons, but remember it is not a precise effective APR.

For a more exact comparison, compute the internal rate of return (IRR) on the actual lease cash flows (this requires modelling the payment stream and any terminal cash flows). If you need a precise APR equivalent, use an online calculator or spreadsheet that computes IRR rather than relying on the 2400 shortcut.

To convert APR to money factor (approximate):

\text{Money factor} \approx \frac{\text{APR (\%)}}{2400}

Caveat: the approximation is acceptable for comparison, but for precise effective interest you should compute the IRR of the lease cash flows or ask the lessor for an APR-equivalent disclosure.

Worked examples (equipment lease and vehicle lease) — step-by-step

Below are two step-by-step examples in AUD. Numbered steps match spreadsheet formulas you can copy.

Example A — Equipment lease (business):

Capitalised cost: $10,000
Residual value: $15,000
Term: 36 months
Money factor: 0.00250

Depreciation:
- (50,000 − 15,000) ÷ 36 = 35,000 ÷ 36 = $172.22
Finance charge:
- (50,000 + 15,000) × 0.00250 = 65,000 × 0.00250 = $162.50
Monthly payment:
- 972.22 + 162.50 = $1,134.72

Total paid over term = $1,134.72 × 36 = $10,849.92 Total depreciation recovered = $15,000; total finance charges ≈ $1,849.92

Example B — Vehicle lease (business ute):

Capitalised cost: $10,000
Residual value: $12,000 (55% residual)
Term: 48 months
Money factor: 0.00180

Depreciation:
- (40,000 − 22,000) ÷ 48 = 18,000 ÷ 48 = $175.00
Finance charge:
- (40,000 + 22,000) × 0.00180 = 62,000 × 0.00180 = $111.60
Monthly payment:
- 375.00 + 111.60 = $186.60

Total paid = $186.60 × 48 = $13,356.80 Total finance charges ≈ $13,356.80 − $18,000 = $1,356.80

Amortisation snapshot (first 3 months — equipment lease example):

Month	Depreciation	Finance charge	Monthly payment	Cumulative paid
1	$972.22	$162.50	$1,134.72	$1,134.72
2	$972.22	$162.50	$1,134.72	$2,269.44
3	$972.22	$162.50	$1,134.72	$3,404.16

When checking quotes, compare both monthly payment and total cost (sum of payments plus any fees minus residual guarantees if applicable).

Calculator-ready formulas (spreadsheet)

Inputs:

CapitalisedCost
ResidualValue
TermMonths
MoneyFactor

Spreadsheet (Excel / Google Sheets):

Depreciation per month:

= (CapitalisedCost - ResidualValue) / TermMonths

Finance charge per month:

= (CapitalisedCost + ResidualValue) * MoneyFactor

Monthly payment:

= Depreciation + FinanceCharge

Example cell references:

A1 = 50000 (CapitalisedCost)
A2 = 15000 (ResidualValue)
A3 = 36 (TermMonths)
A4 = 0.0025 (MoneyFactor)
A5 (Depreciation) = (A1-A2)/A3
A6 (Finance) = (A1+A2)*A4
A7 (Monthly) = A5 + A6

Comparing leases and loans — how to evaluate total cost

When comparing a lease to a loan (e.g., chattel mortgage or business loan), consider:

Total cost over term:
- Lease: Sum of all lease payments plus any fees plus residual guarantee (if payable)
- Loan: Monthly loan repayments plus balloon payment (if any) plus fees plus interest
Effective interest: Convert money factor to approximate APR (money factor × 2400) or calculate IRR for a precise comparison.
Ownership and residual risk:
- Loan: you own the asset; residual risk is yours but sale proceeds accrue to you.
- Lease: lessor owns; at end you may pay a residual to buy or return the asset — market value risk affects final cost if residual guarantees exist.
Tax and GST effects. GST timing can favour leases for cashflow because GST on purchase is claimed upfront for loans when you buy the asset, whereas for lease payments GST is claimed progressively.
Fees & add-ons: acquisition fees, monthly administration fees, early termination penalties, documentation fees — these can materially change the effective cost.
Flexibility: leases can allow easier upgrades; loans may offer lower long-term cost if you keep the asset beyond the repayment period.

Practical comparison steps:

Calculate monthly payments and total payments for both lease and loan.
Convert money factor to APR (approx) or compute IRR for both structures.
Add fees, consider GST timing, and model residual sale proceeds under conservative and optimistic scenarios.
Consider operational needs: maintenance, upgrade cycles, and off-balance-sheet preferences.

Tax, GST and accounting considerations (practical pointers)

Key tax and accounting points (general guidance only):

Lease classification:

Operating lease: lease payments are generally deductible as an operating expense; asset and liability often stay off the balance sheet under some accounting standards.
Finance lease (capital lease): economically similar to a purchase; the asset and liability are recognised on the balance sheet and depreciation and interest are recorded separately.

GST on lease payments:

GST is typically payable on each lease instalment. You can claim input tax credits for business-registered entities on the GST component of the lease payment if eligible, per ATO rules.

Input tax credits for asset purchases:

If you buy an asset (loan/chattel mortgage), you claim GST input credit on the purchase price in the quarter of purchase (cashflow impact differs from lease).

Depreciation vs deductions:

For finance leases, depreciation is claimed by the lessee if accounting rules treat it as an asset on the balance sheet; check ATO guidance for specific treatment.
For operating leases, lease payments are commonly deductible as an expense.

Fringe Benefits and vehicle leases:

Vehicle leases used for employees may have FBT implications; consult the ATO for tax specifics.

Negotiation tips & common pitfalls

Tips to improve terms and lower the money factor:

Know the market: convert quoted money factor to APR (approx) and compare with market loan rates.
Ask the lessor to show the money factor calculation and the buy rate vs markup.
Put down a larger capital deposit to reduce capitalised cost and the finance charge base.
Negotiate residual: a higher residual lowers monthly payments but increases end-of-lease risk.
Shop multiple quotes and use broker expertise. Brokers can sometimes access lower buy rates for equipment financing.
Watch add-on products (maintenance, GAP insurance, administrative fees) that raise the effective cost.

Common pitfalls:

Confusing money factor with APR without conversion.
Ignoring fees (acquisition, monthly admin, early termination) when comparing offers.
Not checking whether residual guarantees create future liabilities.
Accepting a low monthly payment without evaluating total cost or end-of-term options.

FAQ

What is the difference between money factor and interest rate?

Money factor is a decimal used to compute monthly finance charge in leases. Interest rate (APR) is an annualised percentage. Convert approximately via money factor × 2400 ≈ APR%.

How do I convert a money factor to an APR?

Multiply by 2400 for a quick approximation. For precision, compute the IRR of the lease cash flows or use a dedicated calculator.

How is the monthly lease payment calculated?

Monthly payment = Depreciation + Finance charge, where Depreciation = (Capitalised cost − Residual) ÷ Term and Finance charge = (Capitalised cost + Residual) × Money factor.

Are lease payments tax deductible for my business?

Often yes, depending on whether the lease is operating or finance. Check ATO guidance and confirm with your accountant.

How can I lower the money factor on my lease?

Negotiate the buy rate, increase any upfront deposit, reduce the capitalised cost through better pricing, or shop multiple lenders/brokers.

Does the money factor include fees or insurance?

No — money factor only defines the finance charge. Fees and insurance are usually additional and should be added to the monthly cost or shown separately.

What happens at lease end — who pays the residual?

If you return the asset, you typically owe nothing unless there's a residual guarantee. If you buy the asset, you pay the residual. Check contract terms for residual guarantees and end-of-term purchase options.

How to compare two lease quotes with different money factors and residuals?

Compute monthly payment and total payments for each quote; convert money factor to APR for comparison; model sale outcomes on residuals; include all fees.

Where do I find the money factor on the contract?

Look for "money factor", "MF", or a small decimal in the financing section; if unclear, ask the lessor for a written breakdown.

Is a lease better than a loan for equipment upgrades?

Leases often provide better flexibility to upgrade; loans usually suit long-term ownership. Compare total cost, tax treatment, and operational needs — see leasing vs buying comparison.

Key takeaways

The lease rate factor is a decimal used to calculate only the finance charge portion of a lease payment. Convert it to APR by multiplying by 2400 for quick comparison with loan rates. Always compare total lease cost—not just monthly payment—against loan alternatives, and model the impact of fees, residuals, and tax treatment before deciding.
