Valuation Calculator Shark Tank

Calculate company valuations using Shark Tank deal math to understand investment offers and equity.


How the Valuation Calculator Shark Tank works

Calculate implied valuations from investment and equity offers, compare entrepreneur and investor perspectives, and understand deal structures.

Shark Tank valuation math is simple but critical: investment amount divided by equity percentage equals company valuation.

How it works

Tutorial

Shark Tank negotiations move fast, with entrepreneurs and investors calculating valuations instantly. Understanding the math from both sides-what the entrepreneur is implying and what the Sharks are offering-is essential for investment negotiations. The simple formula (investment ÷ equity = valuation) helps you evaluate any deal quickly.

Use the calculator above to analyze Shark Tank deals from either perspective, or follow the steps below to master valuation calculations yourself.

The Formula

CalculationFormula
Implied ValuationInvestment Amount ÷ Equity Percentage
Equity PercentageInvestment Amount ÷ Company Valuation
Pre-Money ValuationPost-Money Valuation – Investment
Ownership PercentageInvestment ÷ Post-Money Valuation

Step-by-Step Calculation

Let’s work through a Shark Tank scenario from both sides.

Step 1: Calculate Entrepreneur’s Implied Valuation

Entrepreneur seeks $500,000 for 10% equity:

ComponentValue
Investment Requested$500,000
Equity Offered10%
Implied Valuation$5,000,000

Calculation:$500,000 ÷ 0.10 =$5,000,000

Step 2: Understand Pre-Money vs Post-Money

Clarify valuation type:

Valuation TypeCalculationAmount
Post-Money (Shark Tank standard)$500K ÷ 0.10$5,000,000
Pre-Money$5,000,000 – $500,000$4,500,000
Entrepreneur Retains100% – 10%90%

Reasoning:Shark Tank uses post-money valuation. The company is valued at $5M after the investment.

Step 3: Analyze Shark’s Counter-Offer

Mark Cuban offers $500,000 for 25% equity:

ComponentValue
Investment Offered$500,000
Equity Requested25%
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:

PartyValuation
Entrepreneur’s Ask$5,000,000
Cuban’s Offer$2,000,000
Difference$3,000,000
Cuban Values At40% of Ask

Calculation:$5,000,000 – $2,000,000 = $3,000,000; $2,000,000 ÷ $5,000,000 =0.40 = 40%

Step 5: Explore Middle Ground

Calculate potential compromise scenarios:

ScenarioInvestmentEquityValuation
Original Ask$500K10%$5.0M
Option 1$500K15%$3.33M
Middle Ground$500K20%$2.50M
Cuban’s Offer$500K25%$2.0M

Calculation for middle:$500,000 ÷ 0.20 =$2,500,000

Step 6: Calculate Final Ownership Stakes

If they agree at 20% for $500K:

PartyOwnershipValue at $2.5M
Entrepreneur80%$2,000,000
Mark Cuban20%$500,000
Total100%$2,500,000

Calculation:$2,500,000 × 0.80 = $2,000,000; $2,500,000 × 0.20 = $500,000

Step 7: Evaluate Dilution Impact

Compare entrepreneur’s position across scenarios:

ScenarioEntrepreneur KeepsValue 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
Difference (Ask vs Compromise)10%$1,000,000

Calculation:$10M × 0.90 = $9M; $10M × 0.80 = $8M; $10M × 0.75 = $7.5M; $9M – $8M =$1M difference

Final Answer:At the compromise valuation of$2.5M, the entrepreneur gives20% equityfor$500K, retaining an80% stake worth $2M

What This Means

Valuation negotiation is about finding a number both sides believe the company is worth. Giving up 20% instead of 10% means giving away twice as much of your company. That extra 10% could be worth $1 million or more at exit, which is why the percentages matter so much.
