10% and 50% overtime
My allowance is £1300 a month
if I do overtime my weekly wage will add up over the month to around £1500 is the 10% that I am alloud to keep based on 10% of the allowance which would be £130 or 10% of my wage with overtime which would be £150 before the 50% ruling kicks in.
If your wage was calculated at £1,300 for the purpose of the IVA, and you earn £1,500 - then your 10% allowance is £130, and therefore you would be required to pay over £35 to the IVA - ie 50% of £70.
