About this app

Stop guessing at checkout. Sales Tax & Discount Calculator gives you the out-the-door total fast—after percent-off discounts, coupons, rebates, sales tax, and tip. It also handles multiple local taxes (state + county + city) and reverse calculations when you only know the final total. Great for questions like: • “What’s the final price after 20% off and 8.25% sales tax?” • “How much do I pay after a coupon and tax?” • “What’s 30% off $79.99, then tax?” • “If the total is $108.37, what was the pre-tax price?” • “What’s the subtotal before tax?” / “What’s the after-tax total?” • “What’s the total with state + county + city tax?” • “How much should I tip on $42.50 at 18%?” • “Split this bill between 3 people (with tip).” FEATURES • Sales tax calculator with quick tax-rate changes • Discount & rebate calculator (percent off) • Apply up to 3 sales taxes (e.g., state + county + city) • Reverse price calculation (work backward from the total) • Tip calculator (percentage) • Split bills in seconds • Share results via Messages or email • Works great on iPhone & iPad (Split View / Slide Over, landscape) Whether you’re shopping, dining out, or comparing prices, this app is a fast way to double-check totals before you pay—so you know exactly what you’re spending.

Minor bug fix

Momentum comes from crawler snapshots for the tracked storefront. “Viral growth signal” means unusually fast recent rating gains; it is an indicator, not download data.
