Shopping Habits
Product Comparison


This calculator helps you quantify the savings from choosing generic or store-brand products over name brands—whether at the grocery store, pharmacy, or retail shops.

How It Works

  1. Enter product comparisons (name-brand vs. generic)

  2. Input your purchase frequency

  3. See annual & lifetime savings (with optional investment growth)


Key Inputs

FieldExample Value
Name-brand item price$5.99
Generic item price$3.49
Quantity purchased per month4
Years to calculate5
Investment return (optional)5%

Savings Formula

Monthly Savings:
(Name-brand price - Generic price) × Monthly quantity

Annual Savings:
Monthly savings × 12

Lifetime Savings (with investment growth):
Annual savings × [(1 + r)^t - 1]/r
(Where r = annual return, t = years)


Example Calculation

Scenario:

  • Tylenol (100ct): $8.99 vs. Store-brand acetaminophen: $4.99

  • Buy 1 bottle/month

  • 5-year timeframe

  • Investing savings at 5% return

Results:

MetricAmount
Monthly savings$4.00
Annual savings$48.00
5-year savings (invested)$272.43

Common Areas for Savings

  1. Groceries (cereal, spices, canned goods)

  2. Medications (pain relievers, allergy meds)

  3. Household items (cleaning supplies, ziplock bags)

  4. Baby products (diapers, formula)

Pro Tip: The FDA requires generic drugs to have identical active ingredients as name brands.


Advanced Features

  • Brand premium % (Calculate how much more you're paying for branding)

  • Price-per-unit comparison (Sometimes generics aren't cheaper per ounce)

  • Store-specific comparisons (Costco Kirkland vs. Walmart Great Value)

Sample Output:
*"Choosing store-brand ibuprofen saves the average family $86/year - enough to cover a monthly utility bill."*


Why This Matters

  • A family of 4 can save $1,200-$2,500/year on groceries alone

  • These savings could grow to $25,000+ if invested over 20 years

  • Identical quality in 90% of cases (Consumer Reports studies show most consumers can't taste/notice differences in blind tests)
