Formula
Unit price = total price ÷ quantity. Compare across package sizes: the smaller unit price usually wins, but not always, storage and spoilage can offset bulk savings.

Frequently Asked Questions
How is the percentage computed?
(Achieved / Actual / Total / Maximum) × 100. The result tells you what fraction of the Total / Maximum the Achieved / Actual represents. For inverse questions ("what's X% of Y?"), swap the inputs accordingly.
What if my percentage is over 100%?
Means Achieved / Actual exceeds Total / Maximum. Common in growth calculations (sales doubled → 200%) or ratios where the "part" can legitimately exceed the "base." If unexpected, double-check your inputs.
Should I round the result?
For reporting: round to 1 decimal place (e.g., "23.4%"). For internal calculations: keep full precision. Conversion rates and engagement metrics conventionally show 2 decimals (e.g., "3.42% CTR").
What's a meaningful percentage in my context?
Depends on the metric. Conversion rate: 1–5% typical for SaaS landing pages. Engagement rate: 3–6% for mid-tier influencers. Tax rate: federal effective is 12–22% for most middle-class earners. Compare to industry benchmarks to interpret your number.
