Ability to enter tax #2

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
For example the total bill is $20, tips is 15% and tax is 8%. Before the
split it will be $20 x 1.23 = $24.60.

Thanks.

Just to restate it in my own words, you're looking to calculate the tip based 
on the actual service, and not 
include the government's tax of that service. So, on a $20 bill, the 8% tax 
would be $1.60.

On $20, a 15% tip would be $3.00, making the total (bill + tax + tip) to be 
split, as you say, $24.60.

Currently, because tax is assumed to be already included when entering the bill 
amount, on a $20 service, the 
user enters $21.60, tips 15% on that ($3.24), leaving $24.84 before splitting, 
the extra $0.24 coming from 
calculating 15% of $1.60 (alternately 8% of $3).

The issues I see with offering this option:
a) Around where I live, the tax can vary by county and/or city, making the 
calculation vary depending on 
where you're eating. Finding the exact tax % is a pain and not exactly 
stimulating dinner conversation.
b) To avoid lots of data entry on what should be a quick and simple operation, 
the app would need to persist 
the tax settings. Persisting the tax however, introduces inaccuracy when the 
tax % changes (see above).

Anyway, if the app were able to more flexibly calculate bill, tip, and tax, and 
still remain simple to do data 
entry, I can see this being used. I'll see what I can come up with. Thanks for 
the input!
