A group dinner comes with a 10 percent voucher, local tax, and a tip nobody wants to calculate on a phone at the table. Shops and freelancers face the same puzzle with invoices. This calculator lays out each step so the total is easy to check.
Enter the bill amount, a discount percentage, a VAT or sales tax percentage, a tip percentage and the number of people splitting. The calculation runs in a fixed order. First the discount is taken off the original amount. Tax is then charged on either the discounted amount or the original amount, depending on the 'Tax applies to' setting. The tip is calculated on the discounted amount before tax. The total is the discounted amount plus tax plus tip, and when the split is more than one, a per-person line divides it evenly.
The breakdown shows each line rounded to two decimals, so you can see where every unit of currency went. That ordering matters: some places tax the pre-discount price on coupon sales, and tipping on the pre-tax amount is a common convention, but local rules vary. When the rules differ from yours, adjust the setting or work the figures in the Percentage Calculator. If you need to send the result as a formal bill, the Invoice Generator builds one.
No currency symbol is applied, so the numbers work for any currency. Everything is calculated in this tab and nothing is saved.

Before tax. The tip is a percentage of the discounted amount, not of the amount including tax. If you prefer to tip on the full total, raise the tip percentage slightly or calculate it separately.
Some jurisdictions charge sales tax on the pre-coupon price for manufacturer coupons or certain promotions. If you are unsure, check the receipt or your local tax guidance and pick the setting that matches.
Each figure is rounded to two decimals for display. Splitting a total three ways can leave a difference of one cent, which someone will need to cover.
