📚 Business percentage calculators
This hub routes commerce percentage questions—discounts, tax on price, tips, commissions, margin, and markup—to single-intent calculator pages.
Each tool keeps one canonical formula (e.g. discount off list, margin on revenue, markup on cost).
Use case: Retail pricing, payroll raises, gratuity splits, and tax-inclusive quotes.
How to use this hub
This business hub links discount, margin, markup, tip, commission, and tax calculators—each page keeps one commerce formula so pricing stories stay consistent.
Given: Cost is $40 and shelf price is $50.
- Margin = (50 − 40) ÷ 50 × 100 = 20%.
- Markup = (50 − 40) ÷ 40 × 100 = 25%.
Answer: Same price pair yields different margin and markup percents—use the term your finance team expects.
Common mistakes: Using markup percent when stakeholders mean margin on revenue, or applying tax to a post-discount base without checking policy.
Margin or markup?
Open margin when profit is measured on revenue; open markup when measured on cost.
How do stacked discounts work?
Use successive percentage—do not add discount rates directly.
Where is sales tax handled?
Use the tax calculator on the taxable base; confirm whether tax is applied before or after discounts.
