Here’s a step-by-step guide, extended explanations, and real-world applications to ensure clarity:

Step-by-Step Calculation

  1. Find 5% of the original amount:
    • Convert 5% to a decimal:   5% = 5 / 100 = 0.05 
    • Multiply by the original amount:     Discount Amount=0.05 × Original Price 
  2. Subtract the discount from the original amount:

Discounted Price = Original Price − Discount Amount 

Shortcut Formula:

Discounted Price = Original Price × (1−0.05) = Original Price × 0.95 

Alternatively, you can use our Percent Off Calculator. Simply enter the number of original price, and it will automatically calculate the 5% off price for you.

Final price:
$0.00
Saved:
$0.00

Examples

  1. Item priced at $200:
    • Discount amount: 0.05 × 200 = $10 
    • Final price: 200 −10 = $190 
      Shortcut: 200 × 0.95 = $190 
  2. Service fee of $45 with a 5% discount:
    • Discount: 0.05 × 45 = $2.25 
    • Final cost: 45 − 2.25 = $42.75 
  3. Decimal value: $79.99 product:
    • Discount: 0.05 × 79.99 ≈ $4.00 
    • Final price: 79.99 − 4.00 = $75.99 

Key Applications

  1. Retail Sales:
    • “5% off” promotions on clothing, electronics, etc.
  2. Budget Adjustments:
    • Reducing project costs or expenses by 5%.
  3. Financial Calculations:
    • Calculating interest rate reductions or fee waivers.

Common Misunderstandings

  • “5% off” vs. “5% of”:
    • “5% off” means subtract 5% from the original.
    • “5% of” means calculate 5% of the original (e.g., tax or tip).
  • Decimals and Rounding:
    • For non-whole numbers (e.g., $49.95), use exact decimal calculations to avoid errors.

Extended Scenarios

  1. Stacked Discounts:
    • Example: 5% off, then another 10% off.
      • First discount: 100 × 0.95
      • Second discount: 95 × 0.90 = 85.5 
  2. Reverse Calculation:
      • If the discounted price is $95, find the original price:

  3. Tax or Markup After Discount:
      • Add 8% tax to a $190 discounted item:Total = 190 × 1.08 = $205.20
