Shark Tank Deal Calculator
Compare an entrepreneur’s ask with a Shark’s offer. Enter the money and equity on both sides to see what happened to the valuation and how much more of the company the Shark wants.
An entrepreneur asks for $200,000 for 10%. A Shark comes back with the same $200,000, but wants 20%. The money did not move at all. Still, those are two very different deals.
This calculator puts them next to each other. Add the original ask and the Shark’s offer, and you can see the valuation behind both numbers, the change in equity and how far apart the two sides really are.
Entrepreneur’s Ask
Enter the terms the entrepreneur asked for.
Shark’s Offer

Deal Comparison
How Does a Shark Tank Deal Comparison Work?
Every simple cash-for-equity offer has a valuation sitting behind it. So when the entrepreneur changes the money, the equity, or both, the valuation can move too. The same thing happens when a Shark makes a counteroffer.
That is what this calculator is comparing. It works out the valuation behind the entrepreneur’s ask and then does the same thing with the Shark’s offer. After that, you can see the two deals without having to keep all four numbers in your head.
A Simple Shark Tank Example
An entrepreneur asks for $200,000 for 10%. That puts the business at a $2 million implied valuation.
Now a Shark offers $200,000 for 20%.
The Shark did not offer less money. The Shark asked for twice as much of the company, and the valuation behind the offer fell by half.
Sometimes the Shark Changes the Money Too
Not every counteroffer keeps the investment the same. A Shark might put more money on the table and ask for more equity with it. That makes the comparison a little harder to see just by listening to the percentages.
For example, $100,000 for 10% values a company at $1 million. An offer of $200,000 for 20% also values it at $1 million. The Shark is asking for twice the equity, but the Shark is also putting in twice the money. In that case, the valuation itself did not change.
A Bigger Equity Percentage Does Not Tell the Whole Story
It is easy to look at 10% and 20% and stop there. But the investment amount belongs beside the percentage. Twenty percent for $500,000 is not the same deal as 20% for $100,000, even though the ownership number looks identical.
That is why the calculator keeps the investment and equity together. It shows what each complete pair of numbers says about the business instead of treating the percentage by itself.
Accepted on TV Does Not Always Mean Money Was Invested
The calculator compares the terms being discussed. It does not tell you whether a deal later closed after filming. An entrepreneur can accept an offer in the Tank and the agreement can still change during due diligence, or it may not close at all.
So the numbers here are useful for understanding the negotiation you are watching. They should not be treated as proof that the Shark eventually invested under those exact terms.

Shark Tank Deal Calculator FAQs
How do I compare a Shark Tank ask and offer?
Enter the investment and equity from the entrepreneur’s ask, then enter the investment and equity from the Shark’s offer. The calculator works out the implied valuation for each set of terms.
What happens if the Shark offers the same money for more equity?
The implied valuation goes down. For example, $200,000 for 10% implies $2 million, while the same $200,000 for 20% implies $1 million.
Can two different deals have the same valuation?
Yes. $100,000 for 10% and $200,000 for 20% both imply a $1 million valuation.
Does a higher investment always mean a higher valuation?
No. The equity percentage matters too. The valuation comes from the relationship between the investment and the ownership percentage.
Does this calculator show whether a Shark Tank deal closed?
No. It compares the deal terms only. An accepted on-screen agreement and a completed post-show investment are separate questions.
