Stop confusing margin with markup.
See your real profit limits.
Offered a 20% discount and ended up losing money? Enter your cost and markup — Margin Pro computes a complete discount schedule, visualizes your break-even zero point, and calculates net revenue factoring in taxes.
The Costly Retail Math Trap
A 50% markup does not mean you pocket 50% profit. In reality, your gross margin is only 33.3%.
- • Unplanned sale losses: applying a 25% markup and offering a 20% discount leads straight to a net loss once taxes are applied.
- • The percentage illusion: discounts are deducted from the retail price, whereas markup is added to cost. They are not equal.
- • Mental calculations: doing napkin math or opening complex spreadsheets during customer negotiations takes too long.
- • Full discount matrix: instant step-by-step table (1% or 5% steps) mapping prices, profits, and margins down to negative territory.
- • Break-even curve: visual zero line clearly highlighting the maximum safe discount before you begin losing money.
- • Smart taxes: seamless calculations with built-in or custom tax rates (0%, 5%, 7%, 20%, or custom VAT/Sales tax).

Frequently Asked Questions
What is the difference between Margin and Markup?
Markup represents the percentage added on top of your product cost: (Profit / Cost) × 100%. It can exceed 100%, 300%, or more.
Margin is the share of pure profit in your final selling revenue: (Profit / Selling Price) × 100%. Margin can never exceed 100%. Confusing the two often leads to setting deeply unprofitable discounts.
How does the app determine the break-even point?
Based on your cost, markup, and tax settings, the algorithm calculates the exact minimum selling price required to cover expenses. Both the table and the chart highlight the maximum safe discount where profit reaches zero.
Does this app require internet connectivity?
No. Margin Pro does not connect to external servers, operates 100% locally, and keeps all calculations safely stored inside your phone database.
