Why examples help

Percent language is abstract. Pairing dollars, counts, or scores with the percent makes audits easy and reduces misinterpretation.

Formula

((original − new) / original) × 100

Keep units consistent: do not mix monthly and annual numbers without converting.

Five quick patterns

  1. Discount: $80 to $60 → 25% decrease.
  2. Revenue: $420k to $357k → 15% decrease.
  3. Quote: $12.50 to $11.00 per unit → 12% decrease.
  4. Population: 48,200 to 47,100 → about 2.28% decrease.
  5. Value estimate: $22,000 to $18,000 → about 18.18% decrease (simple two-point comparison, not a full accounting schedule).

Walk through one discount

Original $80, sale $60. Numerator 20, denominator 80, ratio 0.25 → 25% decrease.

If tax is included in both numbers consistently, the percent still describes the change between those two totals.

FAQ

Can I mix currencies?
Only if both values are in the same currency or you have already converted with an explicit rate.
What if the “original” is an estimate?
Say so. Percent decrease is only as solid as the baseline readers accept.
