How do I calculate sales tax?

To add tax, multiply the price by the rate (8% = 0.08) and add it: $50 at 8% is $4 tax, $54 total. To find the tax inside a tax-included price, divide by 1 plus the rate: $54 / 1.08 = $50 before tax, so $4 was tax.

What people ask

Pain point

How can I add sales tax to a price quickly?

PAnswer from Pludor

Enter the price and tax rate in Pludor's free Sales Tax Calculator. It adds the tax and shows the total - or works out the tax inside a price that already includes it (VAT or GST style).

Pain point

How can I work out how much VAT is in a price?

PAnswer from Pludor

Choose "already includes tax" and the calculator divides it out: price / (1 + rate).

Problem

Why is taking tax out not the same as subtracting the rate?

PAnswer from Pludor

Tax is added on the pre-tax price, so removing it means dividing by (1 + rate), not subtracting the percentage.

Choosing a tool

From result to running business: Pludor Checkout & Payments

Stitching together a payment processor, an invoicing tool and a way to take in-person payments is expensive and leaves money scattered across systems.

Pludor checkout runs on Stripe Connect so buyers pay by card, Apple Pay or Google Pay (or Pludor wallet balance) and money is paid out to the seller's own bank account; the same rails power QR instant-pay links and client invoices.

On for every store, including the Free plan ($0, no item limit). Every feature is on for every store. Each month a free amount of everything is included (for example 3,000 visits, 100 AI replies and 30 bookings); past that you pay only for what you use, in credits (1 credit = 1 cent). New stores get 500 free credits. Monthly plans are optional bundles of credits with bigger free amounts and a lower fee. Pludor charges a platform fee of 4.99% + $0.90 per paid online order, deducted before payout. Card processing (Stripe) is charged separately by the processor. Cash sales recorded in POS carry no platform fee, and wallet-to-wallet transfers between Pludor users are free.
