$($counter to create a definite, counter$-$controlled loop$)$

Develop a retirement planning tool using that lets users input the years left in their working career and the annual amount they can save. The tool should calculate a schedule showing the user's savings at the start of each year in retirement, assuming a $3$ percent simple interest rate on savings annually. Additionally, the tool should consider that the user will spend $$60,000$ annually in retirement and earn $3$ percent interest on the remaining balance. The schedule should cover up to $30$ years or until the user's balance reaches $0,$ whichever occurs first.

Provide users with the option to input the projected number of years until retirement, with the capability to make changes to this input within the program without restarting.

Produce a listing showing the amount of savings the user will need based on spending $$60,000$ per year.

Assume the savings will accumulate $3\%$ interest.

Build based on $30$ years of retirement.

You will verify the functionality of the process by carefully documenting each iteration and inputting the data into the spreadsheet.
