taxes for long term capital gains

I thought I knew the formula for capital gains but I am getting something different. If I make 100k from a sale in 2022 and had no other income as a single filer, would the calculation be this:

 

100k - 41,675 (0% Rate) = 58,325 - 12950 (Standard Deduction) = 45,375 x .15 (15% Rate) = 6,806.25

This is what I get though: 6,642

 

Then CO State taxes calculated like this:

100k - 12950 (Standard Deduction) = 87,050 x .044 = 3830.2

This is what I get though: 3,837

 

Where am I going wrong? Or am I right?
