How it works
Tutorial
Shark Tank negotiations move fast, with entrepreneurs and investors calculating valuations on the fly. Understanding the math from both sides—what the entrepreneur is implying with their ask and what the Sharks are offering with their counter—is essential for anyone entering investment negotiations. The simple formula (investment ÷ equity = valuation) masks important nuances about pre-money vs post-money valuations that can cost founders millions.
You have two options: use the calculator above to analyze Shark Tank deals from either perspective, or follow this guide to master valuation calculations yourself.
The Formula
| Calculation | Formula |
|---|---|
| Implied Valuation | Investment Amount ÷ Equity Percentage |
| Equity Percentage | Investment Amount ÷ Company Valuation |
| Pre-Money Valuation | Post-Money Valuation – Investment |
| Post-Money Ownership | Investment ÷ Post-Money Valuation |
Step-by-Step Calculation
Let’s work through a Shark Tank scenario from both entrepreneur and investor perspectives.
Step 1: Calculate Entrepreneur’s Implied Valuation
An entrepreneur enters seeking $500,000 for 10% equity:
| Component | Value |
|---|---|
| Investment Requested | $500,000 |
| Equity Offered | 10% |
| Implied Valuation | $5,000,000 |
Calculation: $500,000 ÷ 0.10 = $5,000,000
Step 2: Understand Pre-Money vs Post-Money
Clarify what type of valuation is being discussed:
| Valuation Type | Calculation | Amount |
|---|---|---|
| Post-Money (Shark Tank standard) | $500K ÷ 0.10 | $5,000,000 |
| Pre-Money | $5,000,000 – $500,000 | $4,500,000 |
| Entrepreneur Retains | 100% – 10% | 90% |
Reasoning: Shark Tank uses post-money valuation by default. The entrepreneur values the company at $5M after the investment.
Step 3: Analyze a Shark’s Counter-Offer
Mark Cuban offers $500,000 for 25% equity:
| Component | Value |
|---|---|
| Investment Offered | $500,000 |
| Equity Requested | 25% |
| Cuban’s Valuation | $2,000,000 |
Calculation: $500,000 ÷ 0.25 = $2,000,000
Step 4: Calculate Valuation Gap
Determine how far apart the parties are:
| Party | Valuation |
|---|---|
| Entrepreneur’s Ask | $5,000,000 |
| Cuban’s Offer | $2,000,000 |
| Difference | $3,000,000 |
| Cuban Values At | 40% of Ask |
Calculation: $2,000,000 ÷ $5,000,000 = 0.40 = 40%
Step 5: Explore Middle Ground Options
Calculate potential compromise scenarios:
| Scenario | Investment | Equity | Valuation | Gap |
|---|---|---|---|---|
| Original Ask | $500K | 10% | $5.0M | +150% |
| Option 1 | $500K | 15% | $3.33M | +67% |
| Option 2 | $500K | 18% | $2.78M | +39% |
| Middle Ground | $500K | 20% | $2.50M | +25% |
| Cuban’s Offer | $500K | 25% | $2.0M | Baseline |
Calculation for middle ground: $500,000 ÷ 0.20 = $2,500,000
Step 6: Calculate Final Ownership Stakes
If they agree at 20% for $500K:
| Party | Ownership % | Value at $2.5M |
|---|---|---|
| Entrepreneur | 80% | $2,000,000 |
| Mark Cuban | 20% | $500,000 |
| Total | 100% | $2,500,000 |
Step 7: Evaluate Dilution Impact
Compare entrepreneur’s position across scenarios:
| Scenario | Entrepreneur Keeps | Value If Exit at $10M |
|---|---|---|
| Original Ask (10%) | 90% | $9,000,000 |
| Compromise (20%) | 80% | $8,000,000 |
| Cuban’s Offer (25%) | 75% | $7,500,000 |
| 10% Difference | 15% | $1,500,000 |
Reasoning: The valuation gap translates to $1.5M difference in founder proceeds at a $10M exit.
Final Answer: At the compromise valuation of $2.5M, the entrepreneur gives 20% equity for $500K, valuing their retained 80% stake at $2M
What This Means
Valuation negotiation isn’t just about the number—it’s about dilution and what percentage you keep. Giving up 20% instead of 10% seems like a 10% difference, but it’s actually giving away twice as much of your company. That 10% could be worth millions at exit, which is why Sharks and entrepreneurs fight so hard over these percentages.
