App Description

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.
