The initial rental payment is calculated as a multiple of the monthly rental, typically you can choose a multiple of 1,3,6,9 or 12 times the monthly rental.   The higher the initial payment, the lower the monthly cost, however it won’t make the overall deal any cheaper – the total cost of the agreement remains the same.
Lower initial rentals are handy in that they keep the up-front cost lower; however, the monthly cost is higher.
When deciding upon what initial payment option to choose, ensure that both the up-front and monthly rental amounts are affordable to you.
Be sure to check out all your options before settling on an initial payment.
