This is part of gw2efficiency. Please report all issues in the central repository.

Install

npm install gw2e-tradingpost-fees

This module can be used for Node.js as well as browsers using Browserify.

Usage

import {subFees, subTax, subListing, listingFee, tax} from 'gw2e-tradingpost-fees'

// Subtract both the 5% listing fee and the 10% tax
subFees(100000)
// -> 85000

// Subtract the 10% tax
subTax(100000)
// -> 90000

// Subtract the 5% listing fee
subListing(100000)
// -> 95000

// Get the 10% tax
tax(100000)
// -> 10000

// Get the 5% listing fee
listingFee(100000)
// -> 5000

But why not just price * 0.85?

Because that's not how it works ingame. It is missing that there is a minimum of 1 copper for the listing fee, tax, as well as propper rounding. Yes, that makes a difference for cheap items.
