Formula Reference

Percentage Formulas Explained

Our calculator uses industry-standard mathematical formulas to ensure precise percentage calculations for education, finance, business, shopping, and everyday use.

Percentage of a Number

Percentage = (Percentage ÷ 100) × Number

Example: 25% of 800 = (25 ÷ 100) × 800 = 200

Percentage Increase

New Value = Original + (Original × Percentage ÷ 100)

Example: Increase ₹1000 by 20% = ₹1200

Percentage Decrease

New Value = Original − (Original × Percentage ÷ 100)

Example: Reduce ₹1000 by 15% = ₹850

Percentage Change

((New − Old) ÷ Old) × 100

Measures the increase or decrease between two values over time.

Percentage Difference

|A − B| ÷ ((A + B) ÷ 2) × 100

Used to compare the relative difference between two independent values.

Find Percentage

(Part ÷ Whole) × 100

Example: 40 out of 160 = 25%
