How it works
Two numbers. One clean answer. Zero term-sheet confusion.
- 01
Drop in pre-money and investment
Pre-money is the valuation BEFORE the investor's check. Investment is the check amount.
- 02
We compute post-money and ownership
Post-money = pre-money + investment. Investor ownership = investment / post-money.
- 03

Why investors talk pre-money and founders should think post-money
Four moves to read term sheets like an investor, not a victim.
01
Always confirm pre or post before celebrating
A '$5M valuation' could be pre-money or post-money. On a $1M raise, the difference is 17% ownership versus 20% ownership. Always ask: 'pre-money or post-money?' before celebrating any verbal offer.
02
Post-money is the number that matters
Pre-money is what the investor pitches. Post-money is what determines your dilution. Investors quote pre-money because it sounds bigger. Convert to post-money mentally on every offer.
03
Don't anchor on round-number valuations
$5M, $10M, $20M valuations are psychological anchors, not market truth. Pre-money should be tied to your traction (typically 5 to 10x ARR for seed). A $5M pre-money on $50k ARR is reasonable. On $500k ARR, it is low.
04
Model the next round before signing this one
If you raise seed at $5M post-money with 20% dilution, what does Series A look like? Healthy: $15M to $25M post-money, 20% more dilution. If your seed terms make Series A math impossible, the seed terms are wrong.
Frequently asked questions
Why do investors always quote pre-money?
Pre-money sounds bigger and makes the company look more valuable without the investor's contribution. It is a normal anchor in negotiations, not malicious. But founders should always convert to post-money to know real dilution.
What is a fair pre-money for a seed-stage SaaS?
Depends on traction. A common heuristic: 5 to 10x trailing ARR for early-stage SaaS. So $50k ARR justifies $2.5M to $5M pre-money. Pre-revenue companies get valued on team, market, and deal heat, not multiples.
Does this calculator include option pool dilution?
No, this is a pure pre/post-money calc. For cap table effects including option pool, use our cap table calculator which models founder, investor, and pool ownership together.
What happens if the investor pushes for a higher pre-money?
Great for you. Higher pre-money means less founder dilution. The trade-off is usually elsewhere in the term sheet (preference, board control, anti-dilution). Look at the whole document, not just valuation.
Should I share my valuation with other investors?
Yes, after you have a signed term sheet from a lead. Before you have a lead, do not anchor on a number. Let investors propose. Once you have a lead, use their pre-money to set the floor for follow-on conversations.
