You may need to track a different commodity for your work bonus. Here's one
way you could do it:
; account Assets:Bonus
; assert (0 <= total)
= %type=discount
(Assets:Bonus) (-1 BON * amount)
2017/01/01 Beginning of month allowance
(Assets:Bonus) = (1000 BON / 2 + 2500 BON / 4)
2017/01/20 Clothes
Expenses:Clothes £20 ; type: discount
Assets:Checking
The trick is to never let BON become 0. I tried to do this with an account
assertion, but it's not working the way I expected:
account Assets:Bonus
assert (0 <= total)
Anyway, the advantages of this method are:
1. The amount of BON in Assets:Bonus is equal to the number of £ you could
spend at a discount.
2. You deal with conversation rates in one place.
3. You (should) be able to trigger an assertion if you attempt to apply your
discount when no more BON is available. Haven't gotten this working yet.
4. You can choose to roll-over BON, or reset it the beginning of each month
(which you'd do with a balance assignment to adjust the total). Haven't
gotten this quite working the way I'd like either.
There are likely more ways to automate this, but I think it should give you
the general idea...
