Discount first, then tax on the reduced price.

What drives the result

Division is the whole method: totals become per-unit, per-day or per-person rates that brands, packs and plans can be ranked on. Annualising exposes subscriptions; unit-pricing exposes shrinkflation; splitting exposes who owes what.

Recommendations

  • •A discount on an inflated “was” price is theatre — track the price history.
  • •Stack coupons post-discount where the till allows.

Educational Content

Introduction

Small money leaks compound: tips, taxes, pack-size traps, per-use costs and subscriptions each look trivial and total enormously. These calculators normalise every figure — per person, per unit, per day — so comparisons are honest.

Concept Explanation

Division is the whole method: totals become per-unit, per-day or per-person rates that brands, packs and plans can be ranked on. Annualising exposes subscriptions; unit-pricing exposes shrinkflation; splitting exposes who owes what.

▸Comparing pack sizes by unit price
▸Annualising subscriptions before renewing
▸Cost-per-use on durables and memberships

  • •Annualised subscription truth
  • •Fair splits with tax and tip
  • •Discount reality after tax

Limitations

  • •Quality differences aren’t priced
  • •Spoilage and waste ignored
  • •Introductory rates expire
  • •Time value of small sums ignored

Best Practices

  • •Always compare unit prices, never pack prices
  • •Annualise every recurring cost yearly
  • •Tip on pre-tax subtotals
  • •Audit subscriptions on renewal dates

Common Misconceptions

Myth: Bigger packs always win
