Frequently Asked Questions
How do I calculate a percentage discount?
To calculate a discount, enter the original price and discount percentage. The calculator will show the discounted price and amount saved using the formula: Final Price = Original Price - (Original Price × Discount % ÷ 100). For example, a 20% discount on $100 results in $80 final price with $20 saved.
How do I calculate VAT (Value Added Tax)?
For VAT calculations, enter the price and VAT rate. To add VAT: Price with VAT = Price × (1 + VAT% ÷ 100). To remove VAT: Price without VAT = Price with VAT ÷ (1 + VAT% ÷ 100). For example, adding 21% VAT to $100 gives $121.
What is the difference between percentage increase and markup?
Percentage increase calculates the new value after adding a percentage to the original. Markup is similar but often used in business contexts for pricing. Both use: New Value = Original Value × (1 + Percentage ÷ 100). The terms are often interchangeable in calculations.
How do I find what percentage one number is of another?
To find what percentage A is of B, use the formula: (A ÷ B) × 100. For example, if A=25 and B=100, then 25 is 25% of 100. This is useful for calculating completion rates, success rates, or comparing values.
Can I calculate compound percentages?
Yes, for compound calculations, apply each percentage sequentially. For example, a 10% increase followed by a 5% discount: Step 1: Value × 1.10, Step 2: Result × 0.95. The calculator handles single operations; for compound calculations, perform multiple steps.
How accurate are the percentage calculations?
The calculator uses JavaScript's built-in mathematical functions with high precision. Results are accurate to multiple decimal places and are rounded appropriately for display. For financial calculations, results are typically shown to 2 decimal places.
