The reason why you get 54145 is because of Integer division. It ignores decimals (rounding down). Ultimately when you do a minus, you get an extra 1.

1: 100000 - 100000/10 = 90000
2: 90000 - 90000/10 = 81000
3: 81000 - 81000/10 = 72900
4: 72900 - 72900/10 = 65610
5: 65610 - 65610/10 = 59049
6: 59049 - 59049/10
= 59049 - 5904 (missing precision)
= 54145 (extra 1, expected 54144)

To bypass, you can do "amount = amount * 90 / 100".

Do not hard-code -1 or +1.

One good example will be 0. After 6 months, it will still be 0. By hard-coding -1, it results in -1 which is wrong.
