Hi, I need to set up a formula for easily getting a petial price for an item, I need a form so i can just type in the cost price of an item and it will work out the retial price, i need it to do the following...

Cost price + 50pence + 25% +17.5% + 5.25% = Retail price for an item.

I am usless using excel so i need it to be as easy as possible

Thanks
