Post-money valuation, new investor stake, and exactly how much you're diluted.
e.g. $5M post-money, 20% investor stake
Pre-money valuation is what your company is worth before new investment comes in. Post-money valuation is pre-money plus the amount raised — it's what the company is worth immediately after the round closes.
New investor ownership equals the amount raised divided by the post-money valuation. If you raise $1M on a $4M pre-money valuation, post-money is $5M, so investors own 1M / 5M = 20%.
Investors typically require a new or expanded option pool to be carved out of the pre-round cap table before their money comes in, so the dilution from the pool falls on existing shareholders — not on the new investors.
This is a directional, single-round model for quick founder math — not a substitute for a real cap table tool or legal counsel. Actual dilution depends on your specific share classes, existing option pool size, and round structure.
