Percentages, tips, sales tax and margins
Percentages, tips, sales tax and margins. Worked out live, with the working shown. Type a number and the answer is already there. No Calculate button, no waiting. EIGHT PERCENTAGE MODES • What is X% of a number • Percentage change from one value to another • X is what percent of Y • Increase a number by a percentage • Decrease a number by a percentage • Reverse an increase: find the value before it went up • Reverse a decrease: find the value before it came down • Turn a fraction into a percentage TIPS, SPLIT ANY WAY YOU LIKE • Tip by percentage, or by a flat amount • Split between 1 and 50 people, with the per-person total • Tip on the bill before tax, not on the taxed total • Handle a service charge that is already on the bill • Work backwards from the total you actually paid • Five rounding rules: round the tip up, the total up, the total to the nearest, or each person's share up. It remembers which one you use. SALES TAX AND VAT • Type any rate, to four decimal places • The tax and the taxed total solve as you type • Your rate is remembered between launches • See what the tax works out to as a share of the final total MARGIN AND MARKUP, ON SCREEN TOGETHER Most calculators make you choose one or the other. This one always shows both. • Enter cost and price: margin and markup both appear • Or type the margin you want, and get the price • Or type the markup, and get the price • Profit and the price multiplier sit alongside EVERY ANSWER SHOWS ITS WORKING Tap any result for the formula, then the same formula with your own numbers in it, then the calculation step by step. Nothing is a black box. A HISTORY THAT STAYS PUT Every tab keeps its own history. Pin the ones you come back to. Swipe to delete, or select several and clear them at once. IPHONE, IPAD AND MAC One app, built for all three. On iPad and Mac it is a real three-column app with its own menu bar, not a stretched-up phone screen. • Light and dark • Dynamic Type, up to the accessibility sizes • Labeled throughout for VoiceOver • Numbers and currency follow your device's region PRIVATE, BECAUSE IT HAS TO BE No ads. No account. No sign-in. There is no networking code in the app at all, so your numbers cannot go anywhere. There is nowhere for them to go. Nothing is kept except the numbers you typed, the mode, the result and the date. One purchase. No subscription.
