## Tool: Percentage Calculator (Calculate Percent, Proportions & Parts) (percentage-calculator)

- **Category**: math
- **Engine Key**: math.percentage
- **Global URL**: https://fnct.net/percentage-calculator

### Direct Answer / Overview
A Percentage Calculator solves the 3 fundamental percentage relationships: **Finding a percentage of a number (P% 	 of  X = (P/100) 	× X)**, **Finding what percent one number is of another (X / Y 	× 100%)**, and **Finding the whole from a percentage (X / (P/100))**.

### The 3 Core Percentage Equations
- **What is P% of X?**: 	Result = (P / 100) 	× X (e.g., 15% of 80 = 12).
- **X is what percent of Y?**: 	Percentage = (X / Y) 	× 100% (e.g., 25 of 200 = 12.5%).
- **X is P% of what number?**: 	Whole = X / (P / 100) (e.g., 30 is 20% of 150).

Enter your **values into the inputs above** to compute instant percentage solutions with full derivation steps.

### Formula & Calculation Logic
```
P% of X = (P / 100) × X
X is what % of Y = (X / Y) × 100
X is P% of Whole = X / (P / 100)
```

Percentage represents parts per one hundred (Latin: per centum).

### How-To Instructions
1. **Choose Calculation Type**: Select what percentage relationship you need to solve.
2. **Enter Numbers**: Input base value and percentage amount.
3. **Review Solution**: View instant calculated answer and simplified fraction step.

### Worked Examples
- **Find 20% of $150**: Input ({"percent":20,"total":150}) → Result: **Result: 30**
- **15% of 80 (= 12)**: Input ({"percent":15,"total":80}) → Result: **Accurate Operational Result**

### Frequently Asked Questions
Q: How do you quickly calculate 10% or 20% in your head?
A: To find **10%**, move the decimal point one place to the left ($85 
ightarrow 8.5$). To find **20%**, calculate 10% and double it ($8.5 	imes 2 = 17$).

Q: Can a percentage exceed 100%?
A: Yes, percentages over 100% indicate that a value is **greater than the original baseline** (e.g., 200% of $50 = $100).

Q: Can I export or share the calculations from this tool?
A: Yes. You can instantly copy formatted results to your clipboard, download high-resolution visual cards, or export complete calculation steps.

## Tool: Fraction Calculator (fraction-calculator)

- **Category**: math
- **Engine Key**: fraction-calculator
- **Global URL**: https://fnct.net/fraction-calculator

### Direct Answer / Overview
A Fraction Calculator computes **rational arithmetic operations (Addition, Subtraction, Multiplication, Division)** across proper, improper, and mixed fractions.

### Core Fraction Operations
- **Addition & Subtraction**: Converts unlike fractions to the **Least Common Denominator (LCD)** before computing numerators (a/b ± c/d = (ad ± bc) / bd).
- **Multiplication**: Multiplies numerators and denominators directly ((a/b) × (c/d) = (a × c) / (b × d)).
- **Division (Reciprocal Law)**: Inverts the divisor fraction and multiplies ((a/b) ÷ (c/d) = (a × d) / (b × c)).
- **Automatic Simplification**: Reduces results to simplest terms using Greatest Common Factor (GCF) factorization.

Enter your fraction numerators and denominators above to compute step-by-step results instantly.

### Formula & Calculation Logic
```
Addition: (a/b) + (c/d) = (ad + bc) / bd
Multiplication: (a/b) × (c/d) = (ac) / (bd)
Division: (a/b) ÷ (c/d) = (ad) / (bc)
```

Fraction rules:
- **Numerator (a, c)**: The top number representing parts taken.
- **Denominator (b, d)**: The bottom number representing total equal divisions (b, d 
eq 0).

### How-To Instructions
1. **Enter First Fraction (a/b)**: Input the numerator and denominator of the first fraction.
2. **Select Arithmetic Operator**: Choose Addition (+), Subtraction (-), Multiplication (×), or Division (÷).
3. **Enter Second Fraction (c/d)**: Input the second fraction and receive instant simplified output.

### Worked Examples
- **Addition: 1/2 + 1/4**: Input ({"n1":2,"operator":"+","n2":4,"d1":2,"d2":3}) → Result: **3/4 (Decimal: 0.75)**
- **Multiplication: 2/3 × 3/5**: Input ({"n1":3,"operator":"*","n2":5,"d1":4,"d2":5}) → Result: **2/5 (Decimal: 0.4)**

### Frequently Asked Questions
Q: What is an Improper Fraction?
A: An improper fraction has a **numerator greater than or equal to its denominator** (e.g. 7/4), which can also be expressed as a mixed number (1 3/4).

Q: How does fraction division work?
A: To divide by a fraction, **flip the second fraction into its reciprocal** and multiply.

Q: Why cannot a denominator be zero?
A: Division by zero is **mathematically undefined** because no number multiplied by zero can equal a non-zero numerator.

## Tool: Average & Descriptive Statistics Calculator (Mean, Median, Mode, SD) (average-calculator)

- **Category**: math
- **Engine Key**: math.average
- **Global URL**: https://fnct.net/average-calculator

### Direct Answer / Overview
An Average Calculator computes **measures of central tendency (Mean, Median, Mode)** and statistical dispersion from a set of numeric values.

### Core Statistical Measures
- **Arithmetic Mean (Average)**: The mathematical sum of all elements divided by total count (mu = sum x_i div N).
- **Median (Middle Value)**: The exact midpoint value when data is sorted in ascending numerical order.
- **Mode (Most Frequent)**: The value(s) appearing with the highest frequency in the dataset.
- **Statistical Range**: The dispersion difference between the maximum and minimum values (	Max - 	Min).

### Academic & Data Analysis Uses
- **Student Exam Scores**: Finding average class performance and median grade boundaries.
- **Salary & Compensation Analysis**: Using Median instead of Mean to prevent high-earner skewness.

Enter your numbers (separated by commas or spaces) above to calculate complete statistical averages instantly.

### Formula & Calculation Logic
```
Arithmetic Mean (x̄) = (x₁ + x₂ + ... + xₙ) ÷ n
```

Statistical formulas:
- **Sum (∑x)**: Total aggregate of all numbers.
- **Count (n)**: Number of data points.
- **Median**: Value at position (n + 1) / 2 for odd counts, or average of two middle values for even counts.

### How-To Instructions
1. **Enter Numbers**: Type or paste your numbers separated by commas, spaces, or line breaks.
2. **Instant Statistical Processing**: The engine parses and sorts your dataset in real time.
3. **View Mean, Median & Mode**: Receive full central tendency breakdown with sum, count, and range.

### Worked Examples
- **Test Scores: 85, 90, 75, 90, 100**: Input ({"numbers":"85, 90, 75, 90, 100"}) → Result: **Mean: 88.0 | Median: 90.0 | Mode: 90**
- **Classroom Test Scores: 85, 90, 78, 92, 88, 76, 95, 89**: Input ({"numbers":"85, 90, 78, 92, 88, 76, 95, 89"}) → Result: **Accurate Operational Result**

### Frequently Asked Questions
Q: When should I use Median instead of Mean?
A: Use **Median** when your data contains extreme outliers (e.g. household incomes or real estate prices), as the Mean is heavily distorted by extreme values.

Q: Can a dataset have more than one Mode?
A: Yes, a dataset can be **bimodal (2 modes)**, multimodal, or have no mode if all values appear with equal frequency.

Q: What formats of number separators are supported?
A: The calculator accepts **commas (,), spaces, tabs, and newlines** interchangeably.

## Tool: Percentage Increase Calculator (Growth Rate & Relative Delta) (percentage-increase-calculator)

- **Category**: math
- **Engine Key**: math.percentageIncrease
- **Global URL**: https://fnct.net/percentage-increase-calculator

### Direct Answer / Overview
A Percentage Increase Calculator determines the **relative growth rate from an initial starting value to a higher final value** expressed as a percentage ([(	Final - 	Initial) / 	Initial] 	× 100%).

### Key Mathematical Steps
- **Step 1: Calculate Absolute Difference**: Delta = 	Final Value - 	Initial Value.
- **Step 2: Divide by Initial Value**: Divide the absolute increase by the original baseline.
- **Step 3: Multiply by 100%**: Convert the decimal ratio into a percentage.

### Key Distinction: Percentage Increase vs Percentage Points
- **Percentage Increase (%)**: Relative rate of change (e.g., interest rate rising from 4% to 5% is a **25% relative increase**).
- **Percentage Points (pp)**: Absolute arithmetic difference (5% - 4% = 1	 percentage point).

Enter your **initial and final values above** to compute exact percentage increase and derivation steps.

### Formula & Calculation Logic
```
Percentage Increase (%) = [(Final Value - Initial Value) / Initial Value] × 100
Absolute Increase = Final Value - Initial Value
```

Measures fractional growth relative to the starting baseline.

### How-To Instructions
1. **Enter Initial Value**: Input original baseline number.
2. **Enter Final Value**: Input new higher number.
3. **Review Growth Metrics**: View absolute change, percentage increase, and step-by-step formula.

### Worked Examples
- **Revenue Growth from $50k to $75k**: Input ({"initialValue":50000,"finalValue":75000}) → Result: **Percentage Increase: 50.0% | Absolute Difference: +$25,000**
- **Decline from 80 to 60 (-25%)**: Input ({"initialValue":80,"finalValue":60}) → Result: **Accurate Operational Result**

### Frequently Asked Questions
Q: What is the difference between a percentage increase and percentage points?
A: **Percentage points** measure the simple arithmetic difference between two percentages (e.g., $10% - 8% = 2	ext{ percentage points}$); **Percentage increase** measures the relative growth ($2 / 8 = 25%$ increase).

Q: Can a percentage increase exceed 100%?
A: Yes, any value that more than doubles experiences a percentage increase greater than 100% (e.g., rising from $10 to $30 is a **200% increase**).

Q: Can I export or share the calculations from this tool?
A: Yes. You can instantly copy formatted results to your clipboard, download high-resolution visual cards, or export complete calculation steps.

## Tool: Discount & Sale Price Calculator (Single & Stacked Coupons) (discount-calculator)

- **Category**: math
- **Engine Key**: math.discount
- **Global URL**: https://fnct.net/discount-calculator

### Direct Answer / Overview
A Discount Calculator determines the **final discounted sale price and total money saved** when shopping promotions or sales tax are applied.

### Core Discount Calculations
- **Final Sale Price**: Original price minus the calculated discount reduction (Final = Price × (1 - Discount%)).
- **Exact Money Saved**: The raw monetary amount deducted from your total checkout bill.
- **Stacked Double Discounts**: Compounding multi-tier promotions (e.g. 20% store sale + additional 10% member voucher).

### Shopping & Retail Applications
- **Black Friday & Seasonal Sales**: Checking actual checkout prices before reaching the cashier.
- **Sales Tax Integration**: Factoring in VAT or state sales tax to compute true out-of-pocket spending.

Enter the original price and discount percentage above to calculate your final sale price and savings instantly.

### Formula & Calculation Logic
```
Discount Amount = Original Price × (Discount % ÷ 100)
Final Sale Price = Original Price - Discount Amount
```

Shopping price formulas:
- Multiplies original tag price by discount rate to compute savings.
- Subtracts savings from original price to determine net cost.

### How-To Instructions
1. **Enter Original Tag Price**: Input the sticker price before any discounts.
2. **Enter Discount Percentage**: Input the percent-off rate (e.g. 20% or 35%).
3. **View Final Price & Savings**: Receive instant final cost and exact dollar savings.

### Worked Examples
- **25% Off on a $120 Jacket**: Input ({"originalPrice":120,"discountPercent":25,"additionalDiscount":0}) → Result: **Final Price: $90.00 | Saved: $30.00**
- **50% Off $250 (= $125)**: Input ({"originalPrice":250,"discountPercent":50,"additionalDiscount":0}) → Result: **Accurate Operational Result**

### Frequently Asked Questions
Q: How do stacked discounts (e.g. 20% + 10% extra) work?
A: The 10% applies to the **already-discounted price**, not the original price, resulting in an effective total discount of **28% (not 30%)**.

Q: Can I calculate fixed cash discounts instead of percentages?
A: Yes, you can input fixed cash coupon amounts directly.

Q: Does this include sales tax calculations?
A: Yes, you can add sales tax or VAT percentage to determine the final checkout total.
