What is a lease rate factor?

A lease rate factor is the monthly rental a lessor charges per dollar of equipment cost, used to price a lease without quoting an annual rate.

Also known as: money factor (US equivalent)

Key points

  • In Australian equipment finance the factor is the monthly rental per dollar, or per $1,000, of the asset's cost.
  • Multiply the cost by the factor for the monthly rental, then by the number of months for the total rental.
  • The US money factor is a different convention: a decimal applied to capitalised cost plus residual value to price the finance charge alone.
  • A factor excludes fees, insurance and GST, so compare total cost over the term, not just the monthly figure.
  • A higher residual lowers the rental but leaves more to pay out or refinance when the lease ends.

an APR is an annualised percentage, while a lease rate factor is a monthly figure per dollar of cost that has to be converted before the two compare

Frequently asked questions

What is the difference between a lease rate factor and an interest rate?

A lease rate factor is a monthly figure applied to the asset's cost to set the rental, while an interest rate is an annualised percentage. Convert the factor to an annual figure, or compute the IRR of the lease cash flows, before comparing. The American money factor is the same idea priced on the finance charge alone.

How is a monthly lease payment calculated?

In Australian equipment finance the rental is the factor multiplied by the cost of the asset, with fees, insurance and GST added. Under the American money factor convention the payment is split instead: depreciation, being cost minus residual divided by the term, plus a finance charge, being cost plus residual multiplied by the factor.

How do I convert a lease rate factor to an annual rate?

An Australian lease rate factor prices the whole rental, so there is no simple multiplier: work out the internal rate of return on the actual rentals, the fees and anything payable at the end. Under the American money factor convention, multiplying by 2400 gives a ballpark annual rate, and dividing by 2400 goes back.

Does the factor include fees or insurance?

No. The factor only prices the rental or, under the American convention, the finance charge. Documentation and establishment fees, monthly account fees, early termination charges and add-ons such as maintenance or insurance are charged separately, and they can materially change the effective cost, so include them when comparing quotes.

How can I get a lower factor on a lease?

Ask the lessor to show how the factor is calculated, including the buy rate versus any markup, and get multiple quotes, including through a broker who may access lower buy rates for equipment finance. A larger upfront deposit or a better price reduces the capitalised cost and therefore the finance charge base.
