Tip and discount tools are percent-of-base calculators with friendly labels. Their accuracy depends entirely on whether you enter the same base the restaurant or retailer uses.

Enter the bill amount and tip percent to get tip and tipped total. Split afterward if needed. Service charges that already include gratuity should not be tipped twice unless you intend to.

Enter the original price and discount percent to see savings and payable price. For sequential coupons, apply the second discount to the already-reduced price.
