For instance, you are selling a wristwatch on your store in Madison, Connecticut, having a net price tag of $300. The amount that a buyer has to pay (including sales tax) on a check out would be:

Manual Method:

Net Price (amount before Tax) of a Wrist Watch: $300

Total Sales Tax rate: 0% (Madison) + 0% (New Haven County) + 6.35% (Connecticut State) = 6.35%

Total Sales Tax amount = $300 x 6.35% = $19.05

Gross Price (Amount after Tax) = 300 + 19.05 = $319.05

It means the amount the buyer has to pay for a Wrist Watch on a cash counter would be $108.25.

Using our Sales Tax Calculator:

  1. Input the $300 Net Price of a Wrist Watch as Amount Before Tax

This is where the Reverse Sales Tax Calculation Kicks in. And luckily, our Connecticut Sales Tax Calculator can perform this calculation like a Pro.


Your buyer has paid $455 for a Wall Clock at your store in Milldale, Connecticut. Now the buyer is inquiring how much the Wall Clock actually cost before the sales tax was added. So you need to follow the steps below to determine the amount before tax (net price) of a Wall Clock:

Gross Price (Amount after Tax) of Wall Clock: $455

Total Sales Tax rate: 0% (Milldale) + 0% (Hartford County) + 6.35% (Connecticut State) = 6.35%

Manual Method:

Gross Price with sales tax = [Net Price × (tax rate in decimal form + 1)]

455 = [Net Price x ((6.35/100) + 1)]

455 = Net Price x 1.06

$429.2 = Net Price

So the original Price (net price) of the Wall Clock was $429.2.

Using our Sales Tax Calculator:
