Python : Can anyone tell me why this while loop is freezing?

I'm trying to get this homework done for class and no matter what I do, it freezes at the while loop. Everything seems correct to me but I am also pretty new to python. Any help would be appreciated.

print("This program will tell you how long it will take you to retire.")

yearlyReturns = float(input("Enter your yearly investment returns (est .05): "))

monthlyWithdraw = float(input("Enter percentage of your savings you will withdraw monthly (est .04): "))

income = float(input("Enter your monthly income: "))

percentSavings = float(input("Enter the percent of your income you save per month: "))

monthlySavings = (income * percentSavings)

expenses = (income - monthlySavings)

expensesTotal = (expenses * 12)

yearlyReturns = (yearlyReturns / 12)

totalAmount = (yearlyReturns * monthlySavings)

retire = (totalAmount * monthlyWithdraw)
months = 0
while retire < expenses:

    totalAmount = (totalAmount + monthlySavings)

    totalAmount = (totalAmount * yearlyReturns)

    months = months + 1

years = (months / 12)
print(income)

print(expenses)

print(monthlySavings)

print("It took ",months," to save enough to retire.")

print("That will be ",years," years.")

print("See what saving a little bit more would do.")

You are never changing the value of retire or expenses within the body of the loop.

Well, you're not changing retire or expenses in the loop, so once you enter the loop, you never leave.

Move the statement retire = totalAmount * monthlyWidthdraw into the loop.
