Pre-money vs Post-money Valuation

Pre-money valuation is the agreed value of a company immediately before new investment is received. Post-money valuation is the company's value immediately after — calculated simply as pre-money valuation plus the new investment amount. These two figures are not interchangeable, and conflating them is one of the most common sources of misalignment between founders and investors at the term sheet stage.

The formula:

Post-money = Pre-money + New investment Investor ownership % = New investment ÷ Post-money

If a company raises ₹2 crore at a ₹8 crore pre-money, the post-money is ₹10 crore and the investor receives 20%. If the same company raises ₹2 crore at a ₹10 crore pre-money, the post-money is ₹12 crore and the investor receives 16.7%. The investment amount is identical; the ownership transferred is different.

Why the distinction matters

Founders occasionally misquote their raises in post-money terms. "We raised at a ₹10 crore valuation" is ambiguous — it could mean ₹10 crore pre-money or ₹10 crore post-money, representing materially different founder ownership outcomes. When a term sheet arrives, the key number to examine is the pre-money valuation — it sets the price per share for the round, which in turn determines how much of the company each new rupee buys.

Ownership calculation example

Each round, the investor's percentage is calculated on post-money. Founder dilution accumulates across rounds — a founder who held 100% pre-seed and participated in the rounds above would hold approximately 51.2% post-Series B (0.8 × 0.8 × 0.8 = 51.2%), ignoring option pool creation.

Option pool and its effect on pre-money

Investors typically require a new employee stock option pool (ESOP) to be created as a condition of a priced round. The standard practice is to create this pool before the investment closes — meaning it comes from the pre-money valuation, diluting only existing shareholders (founders) rather than also diluting the incoming investor.

A term sheet that specifies "₹8 crore pre-money with a 15% option pool on a post-money basis" means the effective pre-money for founders is ₹6.8 crore (₹8 crore × 85%), not ₹8 crore. The investor's ownership is calculated before the option pool; the founders absorb the full option pool dilution.

SAFE and convertible note interaction

When a company has issued SAFEs or convertible notes before a priced round, the conversion of those instruments creates additional shares at the priced round. Whether those converting instruments dilute the new investor or only existing shareholders depends on whether the SAFEs are pre-money or post-money structured:

• Post-money SAFE (YC standard): The SAFE holder's percentage is fixed at signing. Multiple SAFEs issued under post-money mechanics can create significant founder dilution that does not become visible until the priced round.
• Pre-money SAFE: Conversion dilutes both founders and the new priced-round investor proportionally.

Before signing any SAFE or convertible note, founders should model the full dilution table at the expected priced round to see the actual founder ownership outcome.

What founders commonly miss

The option pool shuffle. New investors often request that the ESOP pool be expanded pre-money — which means the dilution is absorbed entirely by founders. The counter-position is to create the option pool post-money, spreading dilution across all shareholders including the new investor.

Liquidation preferences interact with post-money. A 1x non-participating liquidation preference on a ₹5 crore investment gives the investor the right to receive ₹5 crore first in any exit below the post-money valuation before other shareholders see proceeds. The post-money valuation is the break-even point below which the liquidation preference matters.
