Basic utilities for adding, subtracting and getting GST from a value. Has some simple sanitisation to strip out non numeric characters and always return a number.
npm install gst-utils
import useGst from 'gst-utils';
const myValue = 100;
const { gst, amountInclusive, amountExclusive } = useGst(myValue);
console.log(gst) // 13.04
console.log(amountInclusive) // 115
console.log(amountExclusive) // 86.96Visit nzgst.netlify.app
