Percentage Calculator: Master Percentages
Our Percentage Calculator handles all types of percentage calculations you encounter in daily life, from calculating discounts and tips to understanding test scores and financial changes. Percentages represent parts per hundred and are fundamental to shopping, finance, statistics, and countless other applications.
Common percentage calculations:
Shopping & Discounts
- What is 25% off $80? → $20 off, pay $60
- $45 is what % off $60? → 25% discount
- Add 8% sales tax to $100 → $108 total
Academic & Testing
- Scored 42 out of 50 → 84% grade
- What score for 90%? → 45 out of 50
- Grade increased from 75% to 85% → 13.3% improvement
Business & Finance
- Revenue grew from $50k to $65k → 30% increase
- 15% tip on $85 meal → $12.75 tip
- Profit margin: $30 profit on $150 sale → 20%
Ratios & Comparisons
- What % is 15 of 60? → 25%
- 40 is 80% of what number? → 50
- Increase 200 by 15% → 230
The percentage calculator is perfect for:
- Students: Calculate grades, understand test scores, solve homework problems
- Shoppers: Compare discounts, calculate final prices with tax and tips
- Business Professionals: Analyze growth rates, profit margins, and financial metrics
- Teachers: Grade assignments, calculate class averages, set grading curves

Standard Deviation Calculator: Measure Data Spread
The Standard Deviation Calculator is an essential statistical tool that measures how spread out numbers are in a dataset. Standard deviation tells you whether data points cluster tightly around the mean (average) or vary widely. This is crucial for understanding variability in everything from test scores to scientific measurements to financial returns.
What standard deviation reveals:
- Low Standard Deviation: Data points are close to the mean. Example: Test scores of 88, 90, 89, 91, 90 (SD ≈ 1.1) show consistent performance.
- High Standard Deviation: Data points are spread out. Example: Test scores of 65, 95, 70, 98, 72 (SD ≈ 15.4) show high variability.
- Zero Standard Deviation: All values are identical. Example: 5, 5, 5, 5, 5 (SD = 0) shows no variation.
Key Statistical Measures
- Mean (Average): Sum of values ÷ count
- Variance: Average of squared differences from mean
- Standard Deviation: Square root of variance
- Sample vs. Population: Different formulas depending on dataset type
Normal Distribution Rule
- 68% of data: Within 1 standard deviation
- 95% of data: Within 2 standard deviations
- 99.7% of data: Within 3 standard deviations
- (68-95-99.7 Rule) for normally distributed data
Real-world applications:
Education
Analyze test score distributions, grade curves, and class performance consistency.
Finance
Measure investment risk, volatility, and return consistency over time.
Research
Evaluate experimental data reliability, measurement precision, and result significance.
- Quality Control: Manufacturing processes monitoring for consistency
- Sports Analytics: Player performance consistency and team statistics
- Weather Data: Temperature variation, rainfall patterns
- Healthcare: Patient vital signs, treatment effectiveness
- Market Research: Survey response analysis, consumer behavior patterns
Binary Calculator (0 and 1): Computer Math
Our Binary Calculator performs arithmetic operations using the binary number system—the language of computers. Binary uses only two digits (0 and 1) to represent all numbers, which corresponds directly to electrical switches being off (0) or on (1). Understanding binary is fundamental to computer science, digital electronics, and programming.
Binary operations supported:
Arithmetic Operations
- Addition: 1010 + 1100 = 10110
- Subtraction: 1100 - 1010 = 0010
- Multiplication: 101 × 11 = 1111
- Division: 1100 ÷ 11 = 100
Number Conversions
- Binary to Decimal: 1010 → 10
- Decimal to Binary: 10 → 1010
- Binary to Hex: 11111111 → FF
- Hex to Binary: A5 → 10100101
Understanding binary basics:
| Decimal | Binary | Position Values |
|---|---|---|
| 0 | 0000 | 8-4-2-1 place values |
| 1 | 0001 | Just the 1's place |
| 5 | 0101 | 4 + 1 = 5 |
| 10 | 1010 | 8 + 2 = 10 |
| 15 | 1111 | 8 + 4 + 2 + 1 = 15 |
Why binary matters:
- Computer Science: All digital computers operate using binary. Every instruction, piece of data, and program is ultimately binary code.
- Programming: Understanding binary helps with bitwise operations, data structures, and low-level programming.
- Digital Electronics: Circuit design, logic gates, and digital signal processing rely on binary representation.
- Networking: IP addresses, subnet masks, and data transmission use binary at their core.
- Data Storage: File sizes (bits, bytes, KB, MB, GB) are based on binary powers (2¹⁰, 2²⁰, etc.).
- 1 bit = 1 binary digit (0 or 1)
- 1 byte = 8 bits (can represent 0-255)
- 1 KB = 1,024 bytes (2¹⁰, not 1,000)
- ASCII characters use 7-8 bits each
- IPv4 addresses are 32 bits (4 bytes)
