남는 장사 - 마진 및 순이익 계산기

Are you truly running a "profitable business"?

"Profitable Business" is the most complete margin and selling price calculator for online sellers on Smart Store, Coupang, and other online marketplaces. Beyond a simple (selling price - cost of goods sold), it reverse-calculates all hidden fees and taxes to accurately calculate your "final net profit" and "target selling price."

Why Choose "Profitable Business"?

- Target Profit-Based Selling Price Calculation: "I want to make exactly 10,000 won by selling this product?" Enter your target profit or target margin and we'll tell you the exact selling price you should sell for.
- Perfect Commission Calculation: Enter platform fees and payment (PG/card) fees separately to determine your actual settlement amount.
- Perfect Tax and VAT Application: 10% sales VAT is deducted as standard, and even purchase tax deductions refunded upon purchase (tax invoice) are reflected in the cost price. - Shipping and incidental expenses management: Accurately calculate the total payment subject to commissions by distinguishing between free shipping (paid by the seller) and paid shipping (paid by the customer). Don't overlook packaging costs and return on ad spend (ROAS).
- Return risk hedging: Returns are a chronic problem in online sales! By inputting the expected return rate and round-trip shipping costs, statistical losses are deducted from the margin in advance, helping you calculate conservatively and never incur losses.
- Save your own presets: Save the commissions and settings of your favorite online stores as presets and load them with one click at any time. (Default presets provided for Smart Store, Coupang, etc.)
- Calculation history: Save and compare previous calculations to establish optimal pricing policies.

Recommended for:
- Beginner sellers just starting their online store
- Professional sellers who are confused about settlement amounts due to multiple platforms
- Distributors who want to maximize margins while maintaining price competitiveness
