The 4 Most Common Percentage Mistakes People Make
Base Value Confusion
Calculating 20% of 50 ≠ 50% of 20 (results are same but methodology differs)
Percentage Change Errors
Miscounting increase/decrease from original vs new value
Compound Discounts
20% off then 15% off ≠ 35% off (actual is 32% total discount)
Point vs Percentage
Confusing "increased by 5 points" with "increased by 5%"
Real-World Percentage Calculation Examples
Shopping Discounts
A ₹2,499 shirt with "30% + 20% off" actually costs ₹1,399.44 (not ₹1,249.50 as many assume). First 30% makes it ₹1,749.30, then 20% off that.
Exam Grading
Scoring 87/120 = 72.5% (not 87% as students often misinterpret). Our calculator shows exact percentage and letter grade equivalents.
Advanced Percentage Features
Value Before/After
Calculate original amount when you only know the final value and percentage change ("₹1,150 after 15% increase was originally ₹1,000").
Percentage Distribution
Automatically splits any amount by percentage ratios (perfect for commission splits, budget allocations, or recipe scaling).
Pro Tip for Shoppers
When comparing "₹500 off" vs "20% discount", calculate which saves more money based on the original price. For items over ₹2,500, the percentage discount usually wins.
