How 'bout:

def get_rate(balance):
    for threshold, rate in ((100000, .0173),
                            (50000, .0149),
                            (25000, .0124),
                            (10000, .0085),
                            (0, .006)):
        if balance > threshold:
            return rate
    return .0
