A 36-month lease sounds as though it should contain 36 monthly payments. Often it does. But the nominal term and the number of contractual finance rentals are not mathematically identical concepts.
The GPS Novated Lease Interest Rate Calculator therefore asks for them separately.
How fewer rentals can arise
Possible explanations include the settlement date, commencement date, when the first rental is due, how the provider aligns the first payroll cycle and the precise contractual convention used by the financier.
This article does not claim that 34 rentals are standard for a 36-month novated lease. They are not a universal rule. The correct number is the number in the actual finance schedule.
Why timing changes the implied rate
A dollar paid in month 2 has a different present value from a dollar paid in month 1. If a reverse-rate calculation assumes the wrong first-rental period or forces extra rentals into the model, it is solving a different set of cash flows.
For example, a 36-month finance schedule might contain:
- settlement at period 0;
- first monthly rental at period 2;
- 34 monthly rentals through period 35;
- residual at period 36.
That schedule should be modelled exactly as written.
Do not confuse payroll cycles with finance rentals
A three-year employee may have around 78 fortnightly payroll cycles. Those payroll deductions can fund a monthly lease obligation, running-cost budgets and administration. They do not prove there are 78 contractual finance rentals.

What to request from the provider
If the quote is unclear, ask for the finance schedule or written confirmation of:
- first rental date;
- rental frequency;
- number of rentals;
- final rental date;
- residual due date.
Then calculate the implied lease rate using those actual timings.

Frequently asked questions
Why can a 36-month novated lease show fewer than 36 monthly rentals?
The contractual rental schedule can depend on settlement date, first-payment timing and how the lessor counts rental periods. The nominal term and the number of finance rentals are not always identical.
Does fewer rental payments automatically mean the quote is cheaper?
No. Compare the amount financed, each rental, residual, fees and timing together. A different payment count can simply change how the same finance cost is distributed.
What should I use when reverse-engineering the lease rate?
Use the actual contractual rental amount, rental count and timing together with the financed amount and residual rather than assuming one payment for every calendar month.
