Need a discount, percentage of an amount, a part as percentage of total, or an amount split among people? The percentage calculator on Itqan now provides seven modes with currency and decimal precision, plus image, PDF, and print reports.
What is the percentage calculator?
This digital tool handles increase, decrease, discount, percentage of an amount, a part as percentage of total, percentage change between two values, and splitting a percentage of an amount among people or items.
Inputs and result labels adapt to the selected operation. Choose currency and decimal precision, then export a formatted report.
Unlike the VAT calculator, which is built for country tax rates, here you set any percentage for any purpose (discount, raise, tip, markup).
When do you need it?
- Shopping: Price after a “30% off” sale.
- Restaurants: Tip or service charge as a percent of the bill.
- Payroll: Annual 5% salary raise.
- Investing: Gain or loss as percent of capital.
- School: Exam score as percent of total marks.
- Business: Margin or client discount on a quote.
- Pricing: Mark up wholesale cost to a retail shelf price.
Whenever you know the original and the rate but not the final figure, the calculator saves mental math.
Calculation types
Increase
Adds a percent to the original. Formula: change = original × rate ÷ 100; final = original + change.
Example: 5,000 + 10% → change = 500 → final = 5,500. Use for raises, tips, tax added on top, or retail markup.
Decrease
Subtracts a percent from the original. Formula: change = original × rate ÷ 100; final = original − change.
Example: 200 − 15% → change = 30 → final = 170. Use when a price drops, a budget is cut, or stock loses value.
Discount
Same math as decrease, wording suited for retail — output is what you pay after discount. The tool shows “after discount” and “discount amount” instead of generic decrease labels.
Example: 400 with 25% off → you pay 300 and save 100.
Percentage of an amount
Calculates X% of a value and the remainder. Example: 20% of 1,000 = 200, remaining 800.
What percent of total?
Divides a partial value by its total. Example: 250 of 1,000 = 25%.
Percentage change
Compares old and new values and reports percentage increase or decrease plus the numeric difference.
Split among people or items
Distributes a selected percentage equally. Example: split 80% of 1,000 among 4 people to get 200 each, 800 distributed, and 200 remaining.
Real-world scenarios — four common cases
Store discount during a sale
A laptop is tagged at 4,500 SAR with a 30% off weekend promo. Open Percentage calculator, choose Discount, enter 4500 and 30, select SAR, and click Result.
Manual check: 4,500 × 30 ÷ 100 = 1,350 discount → you pay 4,500 − 1,350 = 3,150 SAR. You saved 1,350 — about one-third of the list price. Tap the 10% discount quick button when testing smaller promos without retyping the rate.
Salary raise at year-end review
Your monthly salary is 12,000 SAR and HR confirms a 6% increase. Choose Increase, enter 12000 and 6, currency SAR.
Math: 12,000 × 6 ÷ 100 = 720 → new salary = 12,720 SAR per month. Over twelve months that is 8,640 SAR extra — handy when comparing offers with different raise percentages.
Tip calculation after dinner
The bill is 285 AED and you want to leave a 15% tip. Choose Increase (tip is added on top of the bill), enter 285 and 15, pick AED — or tap the 15% tip shortcut which sets increase mode and 15% automatically.
Tip: 285 × 15 ÷ 100 = 42.75 → total = 327.75 AED. To split it, choose Split among people / items, enter 327.75, 100%, and count 4.
Price markup from wholesale to retail
You buy inventory at 75 USD per unit and target a 40% markup for retail. Choose Increase, enter 75 and 40, currency USD.
Markup: 75 × 40 ÷ 100 = 30 → shelf price = 105 USD. Markup ≠ margin: 30 profit on 105 revenue ≈ 28.6% margin.

Numeric examples
These cases mirror what you might enter in the tool. Verify one by hand if you are learning the math:
| Case | Mode | Original | Rate | Change | Result |
|---|---|---|---|---|---|
| Product discount | Discount | 400 | 25% | −100 | 300 |
| Salary raise | Increase | 8,000 | 8% | +640 | 8,640 |
| Tip on bill | Increase | 120 | 15% | +18 | 138 |
| Tax on subtotal | Increase | 1,000 | 15% | +150 | 1,150 |
| Budget cut | Decrease | 50,000 | 12% | −6,000 | 44,000 |
| Clearance price | Discount | 89.99 | 35% | −31.50 | 58.49 |
Worked example — tax on 1,000: 1,000 × 15 ÷ 100 = 150 added → total 1,150. The 15% tax quick button switches to increase mode and fills 15% for GCC-style VAT added on top of a subtotal.
Quick shortcuts
Three preset buttons sit below the rate field — each sets the mode and percentage in one tap:
- 15% tax — switches to increase, rate 15%. Common in Saudi Arabia and the GCC when adding VAT-style tax to a subtotal.
- 10% discount — switches to discount, rate 10%. Typical retail promo (“10% off everything”).
- 15% tip — switches to increase, rate 15%. Standard restaurant gratuity in many countries.
Shortcuts save taps on mobile — open the tool in the store aisle, enter the shelf price, hit 10% discount, and read the final price before checkout.

Common mistakes
Mixing increase and discount
+10% then −10% does not return to the start — percents compound on different bases. Example: 100 + 10% = 110, then −10% of 110 = 99, not 100.
Applying discount twice
“Extra 20% off already reduced price” means 20% of the current price, not the original tag. Run two calculations: first discount, then use the result as the new original for the second.
Confusing markup with margin
40% markup on cost ≠ 40% margin on selling price. Always state which base the percent applies to.
Skipping currency
Numbers are correct but missing symbols confuse multi-currency reports. Select SAR, AED, or USD when sharing screenshots with colleagues.
Using it for full VAT invoices
For formal VAT line items, seller details, and invoice layout, use VAT calculator or Invoice calculator.
Practical tips
Compare two store offers
Compute final price after each store’s discount — “20% + 10%” ≠ “30%”. Store A: 500 − 20% = 400, then −10% = 360. Store B: 500 − 30% = 350. Store B wins by 10.
Reverse-check a receipt
Decrease mode cannot cleanly strip tax from a tax-inclusive total — use VAT tools. For tax on top of 1,000, increase mode confirms the breakdown.
Save the result
Use the save-as-image button or copy the numbers into email, chat, or a spreadsheet.
On mobile
Responsive layout — handy while shopping in store. Preset buttons reduce typing on a small keyboard.
Pre-calculation checklist
Thirty seconds of review avoids wrong-mode errors:
- Correct mode: increase for tips/tax/markup, discount for sale prices, decrease for reductions not labeled as retail discounts.
- Original value is the right base (pre-tax subtotal for tax-on-top, tagged price before coupon).
- Rate is entered as a plain number (15 for 15%, not 0.15).
- Currency selected if the result goes into a report or message to someone else.
- For stacked promotions, plan two separate calculations — not one combined percent.
- Discount rate does not exceed 100% (the tool validates this).
- Result makes intuitive sense — a 10% discount on 200 should be near 180, not 2,000.
