The five percentage questions

Almost every percentage problem in daily life is one of five questions: What is X% of Y? (15% service charge on a Rs 2,000 bill.) X is what percent of Y? (You scored 45 out of 60.) What is the percentage change from X to Y? (Your shop's sales grew from Rs 80,000 to Rs 100,000.) Add or subtract X% (13% VAT on an invoice, or a 20% discount). And how different are two numbers in percent terms? This tool answers all five live as you type.

Percent of a number, the everyday workhorse

"X% of Y" multiplies Y by X over 100. It covers tips and service charges at restaurants, commission on a property deal, interest for one month on a loan, or how much battery 30% of a 5000 mAh pack really is. The formula is simple but mental arithmetic under pressure is where mistakes happen - letting the tool do it removes that risk.

Marks, discounts and VAT in Nepal

Students converting SEE or NEB marks into percentages, shoppers checking whether "25% off" beats a flat discount, and businesses adding 13% VAT or extracting it from a VAT-inclusive bill all use the same arithmetic. For VAT specifically: to remove 13% from a VAT-inclusive price, divide by 1.13 rather than subtracting 13% - a subtle difference this tool's add/subtract mode makes visible.

Percentage change versus difference

Change compares new against old: (new − old) ÷ old × 100, so going from 80 to 100 is +25%, while 100 back to 80 is −20% - the asymmetry surprises people. Percentage difference instead treats both numbers equally, dividing by their average; it is the right choice when neither value is obviously the "original", like comparing two suppliers' quotes.

Common traps to avoid

Three mistakes cause most errors: applying a percentage to the wrong base (discounting tax along with the price), chaining percentages naively (+10% then −10% does not return to the start - it lands 1% lower), and confusing percentage points with percent (a rise from 10% to 12% is 2 points but a 20% increase). Keeping each calculation in its own card, as here, helps you stay honest about which base you mean.

Frequently asked questions

How do I calculate a percentage of a number?

Multiply the number by the percentage and divide by 100. For example 15% of 2000 = 2000 × 15 ÷ 100 = 300.

How do I find what percent X is of Y?

Divide X by Y and multiply by 100. Scoring 45 out of 60 gives 45 ÷ 60 × 100 = 75%.

How do I calculate percentage change?

Subtract the old value from the new one, divide by the old value, and multiply by 100. A positive result is an increase, negative a decrease.

How do I remove 13% VAT from a price?

Divide the VAT-inclusive price by 1.13. Subtracting 13% gives a slightly wrong answer because the VAT was added on the smaller base amount.

Why did +10% followed by -10% not return to my original number?

Each step uses a different base: after rising 10%, the 10% decrease applies to a larger amount, so you end up 1% below where you started.
