Why am I getting a syntax error when I try to assign the variable 'remainder?'

outbal = float(raw_input('Enter the outstanding balance on your credit card:'))
Annualintrate = float(raw_input('Enter the annual credit card interest rate as a decimal:'))
x = 1.0
month = 1
while (remainder > 0.0):
    while (month <= 12.0):
        initialmonthlyballance = round(float(((annualintrate /12)*outbal)+outbal, 2)
        remainder = round(float(initialmonthlyballance - (x*10)))
    if (remainder >= 0):
        month += 1
        Outbal = reamainder
    else:
        print 'Monthly payment to pay off debt in 1 year:', x10
        print 'number of months needed:', month
        print 'Balance:' remainder
if (reamainder > 0):
        x = x + 1

else:
        print 'Monthly payment to pay off debt in 1 year:', x10
        print 'number of months needed:', month
        print 'Balance:' remainder
