Let’s be real—manually calculating percentages in spreadsheets is about as fun as doing laundry. Whether you’re adjusting prices, calculating tips, or analyzing growth rates, there’s gotta be a better way than reaching for your calculator every time. Good news: Google Sheets has your back, and Excelmatic’s AI can take it even further.
Why Percentages Matter (And Why You Should Stop Calculating Them Manually)
Percentages are everywhere in business:
- Marking up product prices by 15%
- Calculating 20% discounts during sales
- Tracking 5% monthly revenue growth
But here’s the kicker: most people waste hours doing these calculations the hard way. That’s where spreadsheet formulas (and smarter tools like Excelmatic) come in clutch.
The Basic Math You Need (Don’t Worry, It’s Simple)
Before we dive into formulas, let’s break it down:
- 25% = 25/100 = 0.25 (just move the decimal two places left)
- To add 10% to $100: $100 × 1.10 = $110
Pro tip: Excelmatic’s AI understands natural language, so you can literally type “add 10% to 100” and it’ll calculate it for you—no formulas needed.

Here’s how to stop calculating like it’s 1999:
