Hi there 👋 I just want to acknowledge your question. I'm working on other threads and will get to yours soon!

#

thanks for waiting! We round to the smallest currency unit, I believe this is what you might be looking for: https://docs.stripe.com/billing/taxes/tax-rates#rounding

Thats interesting, so looking at the price i mention which is in US Dollar, shouldnt it be rounded up to 10.30 on stripes side ? like in this example here https://docs.stripe.com/billing/taxes/tax-rates?item-or-group-level=line-item-level#rounding The first second one has a price for $4.5455 which is rounded up to 4.55
We have $20.59 with 50% discount which results in $10.295 which i would assume to restult in 10.30, in stripe i can see it still has $10.29 open though

#

Does stripe just cut decimals for the whole invoice ?

#

Will you be able to share with me the invoice ID that's showing $10.29?

#

I have the invoice number is that gonna work out ?

#

Wait does stripe round up discounts and then apply them ?

#

I will need the Stripe account ID as well as I won't be able to look up using the invoice number alone. If you don’t mind, could you share your account id? You can find your account id by logging in to https://dashboard.stripe.com/settings/account . It'll have the prefix acct_

this is the invoice: in_1RnXwdJMuPhqEMciH4by4cmQ give us awhile to take a look at it

#

Okay so the rounding is actually happening for this line item: VIP Discord (All-Access)

#

Firstly, when there's discount on the invoice, the invoice is applied to each line item, the calculation is:

19.99 * 0.5 = 9.995 ~ 10.00 (this is rounded to $10.00)
0.6 * 0.5 = 0.30

#

the invoice total is then calculated from the subtotal like 20.59 - 10.30

#

i hope this clarifies!

#

Hey, taking over here. Let me know if there's any follow-up Qs I can answer!

rain forge Jul 22, 2025, 8:32 AM

#

Ok so we have to calculate the discount per line item not the total

hollow stratus Jul 22, 2025, 8:33 AM

#

Yes.

rain forge Jul 22, 2025, 8:35 AM

#

And for discounts is bankers rounding used or round half up ? So let's say we have a discount of 10.295 I guess it's rounded to 10.30 like in our case so rounding half up instead of bankers rounding

hollow stratus Jul 22, 2025, 8:37 AM

#

It's rounding Up

rain forge Jul 22, 2025, 8:37 AM

#

And for the grand total on the invoice also rounding that up or bankers rounding at that point ?

hollow stratus Jul 22, 2025, 8:50 AM

#

Yeah AFAIK, in Stripe we use the rounding Up
