return calculation every four weeks

[webwolf_3000]

Im new to excel, and just starting to learn programming.

what i want to do is perform a calculation every four weeks.

so if i enter a total, £1,500, every four weeks £10 will be deducted.
any help would be appreciated on this one.

How about a reminder in Outlook? The effort of typing one number once a
month hardly warrants anything fancier.
