This is the payment profile. For instance a 9+23 is a 24-month contract where the initial rental is equivalent to 9 monthly rentals. This is then followed by 23 further monthly rentals. A 6+35 for instance is a 36-month contract where the initial rental is equivalent to 6 monthly rentals, followed by 35 further monthly rentals. The payment profiles can be adjusted to suit you – the initial payment is usually 3, 6 or 9 payments (1 is available from some funders) The larger the initial payment the lower the monthly rental and the lower the initial payment the higher the monthly rental. The total amount you pay will be broadly the same either way.
