## What is Sales Tax Calculator >?

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.

### 5/5 — Free 4 years, now a paid member

*2026-06-29, version 6.4.1*

After using this app for years for free and always happy of the ease and convenience to use it. Today I paid the $4 for use without the ads. I have use it at restaurants for the tips, use it for shopping everywhere and never had issues.

### 5/5 — La mejor

Súper

### 5/5 — Amazing

Very handy , and reliable app.

### 5/5 — Eli

*2025-04-21, version 6.2.3*

Excellent app I couldn’t do without it. Thank you.

### 5/5 — Exceptional

*2025-03-16, version 6.2.3*

Calculating brought to an ease!

### 4/5 — Ad block the calculator

*2025-02-07, version 6.2.3*

The app is designed to have a ad and  it does not go away so the calculator is basically useless.  FAKE!!

### 1/5 — Irritating

*2025-01-04, version 6.2*

One with ads is RIDICULOUS. Can’t get them to go away to even use the app.

### 1/5 — Used to be

*2025-01-02, version 6.2*

It calculates well but now the ads won’t clear off. I keep closing and opening the app and the same ad pops back up and won’t go away even though I’m pressing it to exit out. 
I’ll just go back to doing it the ol fashioned way. App uninstalled.

### 5/5 — Fantastic!

*2024-11-10, version 6.2*

Easy to use, spot on! Every time I need to know the real cost, Sales Tax Calculator is on it!

### 2/5 — Loved it then DESPISED it

*2024-10-25, version 6.2*

As someone who isn’t great at retail math and always miscalculating what I’ll be spending while shopping clearance and sales, this app was a godsend!!! It truly made shopping so much better because I could see exactly how much I’d be spending. I’ve had it for a few months, and now I cannot use the app at all!!!! There is always an ad that pops up and there is no option to close it out. It’s not even a timed ad either where it gives you the option to close it after like 15 sec. It just stays on the screen preventing you from using the app. I’ve tried closing it out and reopening the app like 15 times and it does it every single time now. It was good while it lasted I guess. I HATE ADS
