Use a triple quoted string for multiline output

output = """
At an average weekly savings of \t$%.02f,
your monthly savings  will be     \t$%.02f.
Your annual savings will be       \t$%.02f.
""" % (diff, monthly_savings, annual_savings)

print output

Multiline strings are designed to save you having to do that.
