How dilution works in seconds: Enter valuations with raise sizes to get post-money ownership plus option-pool impacts together. Results appear at $0 cost in your browser.

Why modeling matters for USA founders on 09/22/2026: Each round reshapes all slices — model two rounds ahead always. Austin founders modeling $3M seed-to-Series-A paths protect against surprise cram-downs. Chicago angels tracking $250,000 checks monitor pro-rata rights.

Option grants: Miami employees valuing $400,000 option packages divide fully-diluted shares correctly. Denver bootstrappers weighing $1M revenue-based offers compare dilution-free costs.

Earnout bridges: Seattle acquirers structuring $90M deals bridge valuation gaps with performance payouts. New York funds modeling $500M reserves allocate follow-ons mathematically.

Pool shuffle: Pre-money option pools dilute founders only — negotiate pool sizes as fiercely as valuations.

Robotics rounds: Boston robotics startups raising $20M Series A rounds model employee dilution honestly. Chicago marketplaces raising $9M seed extensions bridge to profitability on 09/22/2026.

Health safes: Miami health startups closing $4M safe rounds track caps plus discounts. Phoenix fintechs raising $30M Series B rounds expand option pools pre-money.

Space contracts: Denver space startups booking $9M government revenue raise less dilutive capital. Pay-to-play provisions punish non-participants.

Frequently Asked Questions

How do you calculate what percent one number is of another in dilution?
Divide the part value by the total value and multiply by 100. For example, to find what percent 75 is of 200, calculate 75 divided by 200 times 100 which equals 37.5 percent. This formula works for any two numbers and is the foundation of all dilution percentage calculations. The Dilution Calculator v2 handles this instantly.
How do I find the original number when I know the percentage for dilution?
Divide the percentage value by the percentage rate expressed as a decimal. For example, if 45 is 30 percent of a number, divide 45 by 0.30 to get 150. This reverse calculation is useful for determining original prices before discounts, finding total dilution amounts from partial information, and working backward from known percentages.
What are the most common uses for percentage calculations in dilution?
Percentages are used for calculating grades, computing discounts and markups, determining tax amounts, analyzing statistics, calculating interest rates, measuring growth or decline, comparing proportions in surveys, and many everyday financial and academic tasks. The Dilution Calculator v2 simplifies all of these dilution percentage scenarios.
Can a percentage in dilution be greater than 100?
Yes, percentages can exceed 100. For example, if a company doubles its revenue from $500,000 to $1,000,000, that represents a 100 percent increase. Values greater than 100 percent indicate that the part exceeds the whole, which commonly appears in growth measurements and comparative analyses within dilution contexts.
How do I calculate the percentage increase or decrease for dilution?
Subtract the original value from the new value, divide by the original value, and multiply by 100. A positive result is an increase, while a negative result is a decrease. For example, a price increase from $80 to $100 represents a 25 percent increase. The Dilution Calculator v2 handles all dilution percentage change calculations automatically.
