Online shoppers frequently encounter promotions such as 30% off plus an additional 50% off. While these offers seem straightforward, calculating the final price manually can be confusing. Many people mistakenly believe that a 30% discount followed by a 50% discount equals an 80% discount. In reality, sequential discounts work differently.

Understanding How Double Discounts Work
Many shoppers assume that:
30% + 50% = 80% off
This is incorrect.
The second discount is applied to the already discounted amount, not the original price.
Example
Original Price = $100
First Discount (30% Off):
30% of $100 = $30
Price After First Discount:
$100 − $30 = $70
Second Discount (50% Off):
50% of $70 = $35
Final Price:
$70 − $35 = $35
Total Savings:
$100 − $35 = $65
Effective Discount:
65%
Although the discounts add up numerically to 80%, the actual discount received is only 65%.
Formula Used by the Calculator
The calculator performs several calculations automatically.
Step 1: Calculate First Discounted Price
P1=P(1−d1)
Where:
- P = Original price
- d₁ = First discount percentage
Step 2: Calculate Final Price
Pf=P1(1−d2)
Where:
- P₁ = Price after first discount
- d₂ = Additional discount percentage
Step 3: Calculate Total Savings
S=P−Pf
Where:
- S = Total savings
Step 4: Calculate Effective Discount
E=PS×100
Where:
- E = Effective discount percentage
Detailed Example
Let’s calculate a common shopping scenario.
Given
- Original Price = $250
- First Discount = 30%
- Additional Discount = 50%
First Discount
30% of $250:
$75
Price after first discount:
$250 − $75 = $175
Additional Discount
50% of $175:
$87.50
Final Price
$175 − $87.50 = $87.50
Total Savings
$250 − $87.50 = $162.50
Effective Discount
($162.50 ÷ $250) × 100
= 65%
Results
| Value | Amount |
|---|---|
| Original Price | $250 |
| Price After 30% Off | $175 |
| Final Price | $87.50 |
| Total Savings | $162.50 |
| Effective Discount | 65% |
30 Off 50 Discount Table
The following table shows common examples.
| Original Price | After 30% Off | After Additional 50% Off | Total Savings | Effective Discount |
|---|---|---|---|---|
| $20 | $14.00 | $7.00 | $13.00 | 65% |
| $50 | $35.00 | $17.50 | $32.50 | 65% |
| $100 | $70.00 | $35.00 | $65.00 | 65% |
| $200 | $140.00 | $70.00 | $130.00 | 65% |
| $300 | $210.00 | $105.00 | $195.00 | 65% |
| $500 | $350.00 | $175.00 | $325.00 | 65% |
| $1000 | $700.00 | $350.00 | $650.00 | 65% |
As you can see, a 30% discount followed by a 50% discount always results in a 65% effective discount.

Common Discount Calculation Mistakes
Adding Discounts Directly
Incorrect:
30% + 50% = 80%
Correct:
30% off followed by 50% off = 65% effective discount.
Applying Both Discounts to Original Price
Some people calculate:
30% of original price plus 50% of original price.
This produces incorrect results because the second discount must be applied to the reduced amount.
Ignoring Effective Savings
A large advertised discount may not always represent the actual savings achieved after multiple calculations.
