A young, investing-savvy artist plans to retire in 30 years and is planning to save $1,000 every month. They plan to deposit the money at the beginning of each month into an account paying 5% compounded monthly. How much will they have in 30 years?

Please work the question out so I can understand it better. Previous person who helped on this used excel and that doesn't really help me with understanding the formulas and break down of the actual problem.
