How to take a percentage off a number
Enter the original and the percentage, and you'll see both the amount removed and what remains.
- 01
Enter the original value
Use the figure before any cut: the full sticker price, last year's budget or your starting weight. The percentage is taken from this number.
- 02
Enter the percentage to take off
Type 25 for 25% off. Decimals work, so 12.5 is fine. The result updates as you type.
- 03
Read the saving and the new value
You get the amount removed (value × rate ÷ 100) and what's left (value − amount removed). A ₹4,999 coat at 30% off saves ₹1,499.70, so you pay ₹3,499.30.
How big a rise it takes to recover from a fall
A fall and the rise that cancels it aren't the same size. After a 20% drop you're working from a smaller base, so you need a 25% rise to get back. The recovery figure is decrease ÷ (100 − decrease), and it climbs fast once the cut passes 50%.
| Decrease | Multiply by | Increase needed to recover |
|---|---|---|
| 10% | 0.90 | 11.11% |
| 20% | 0.80 | 25% |
| 25% | 0.75 | 33.33% |
| 30% | 0.70 | 42.86% |
| 40% | 0.60 | 66.67% |
| 50% | 0.50 | 100% |
| 75% | 0.25 | 300% |
| 90% | 0.10 | 900% |
Investors know this pattern well: a share that falls 50% has to double to break even. It's also why a budget cut of 30% followed by a 30% restoration still leaves a department 9% short (0.70 × 1.30 = 0.91).
Stacked discounts and working backwards
Shops love "30% off, plus an extra 20% at checkout". That isn't 50% off. The second discount comes off the already-reduced price, so you pay 0.70 × 0.80 = 0.56 of the original, a total discount of 44%. To check a stacked offer here, run the first discount, then enter the new value with the second percentage.
Going backwards trips people up too. If you paid ₹3,499.30 after 30% off and want the original price, adding 30% back gives ₹4,549.09, which is wrong. Divide by what you paid as a fraction instead: ₹3,499.30 ÷ 0.70 = ₹4,999.
Everyday percentage cuts
Checking a sale price at the till
Type in the tag price and the discount on the sign. If the receipt shows a different total, you'll know before you leave the counter.
Planning a budget cut
A 12% cut to a ₹50,00,000 annual budget removes ₹6,00,000 and leaves ₹44,00,000. Break that down by month and the number is easier to plan around.
Setting a weight-loss milestone
A 5% reduction from 88 kg is 4.4 kg, giving a first target of 83.6 kg. Smaller percentage goals are easier to track than a single big number.
