How the difference is calculated
Same arithmetic the calculator on every page runs.
Each combined rate is the sum of its listed state, county, city and special-district components — no rounding is applied before the total. The dollar gap is the rate difference (0.25%) applied to the pre-tax amount: 0.25% of $1,000 is $2.50. Neither figure includes product-specific exemptions; groceries, clothing and digital goods can be taxed at a different rate or not at all, which is covered on each state's rules page.
