Dilution Calculator
Pre-money valuation and raise size, turned into the ownership percentage you're actually giving up.
Dilution is the share of the company new investors take on when they invest, calculated as the raise amount divided by the resulting post-money valuation (pre-money valuation plus the raise). A company raising $1.5M on an $8.5M pre-money valuation ends up at a $10M post-money valuation, with new investors owning 15% of the company.
Rounds where new investors end up owning more than 30% in a single raise are on the high end for seed and Series A deals — worth knowing before a term sheet is on the table, not while negotiating it.
This is one round. What about the next one?
