When an investor offers you money, they are really proposing a trade: capital today in exchange for a slice of your company that they keep forever. Valuation is the price tag that decides how big that slice is. Get the mechanics wrong and you can hand away far more ownership than you intended, so every founder needs to understand pre-money, post-money and the dilution math before walking into the room.
What valuation actually is
A startup valuation is not a scientific measure of what your company is truly "worth". At the early stage it is a negotiated number that reflects your traction, team, market size and how badly investors want in. It is set by comparison and negotiation, not by profits you do not yet have. Treat it as a deal term, not a report card.
Pre-money versus post-money
Pre-money valuation is what your company is agreed to be worth before the new money arrives. Post-money valuation is simply the pre-money plus the amount raised. Two equations carry almost everything you need:
- Post-money = Pre-money + Investment
- Investor's ownership = Investment / Post-money
The investor's percentage is always calculated on the post-money number, so "8 crore valuation" means very different things depending on whether it is pre or post. Always confirm which one is on the table.
A worked example in rupees
Say a fund agrees to an 8 crore pre-money valuation and invests 2 crore.
- Post-money = 8 crore + 2 crore = 10 crore
- Investor's stake = 2 crore / 10 crore = 20%
- You and your co-founders drop from 100% to 80%. That drop is called dilution.
Now watch the same 2 crore described as an 8 crore post-money deal instead. Pre-money becomes 6 crore, and the investor takes 2 crore / 8 crore = 25%. Same cheque, 5% more of your company gone. One word changed the outcome.
Working backwards from the ask
Founders usually start from two questions: how much cash do I need, and how much am I willing to give up. Once you fix those, valuation becomes the output, not the input:
Post-money = Investment / dilution you accept.
If you need 2 crore and are comfortable giving up 20%, then post-money must be 2 crore / 0.20 = 10 crore, which implies an 8 crore pre-money ask. If investors will only agree to a 6 crore pre-money, you either raise less or accept more dilution. Raise only what carries you to the next clear milestone. Every extra crore at a fixed valuation costs you ownership.
The option pool trap
Investors often ask you to create or expand an employee stock option pool (ESOP), say 10%, before the round closes. Because it is carved out of the pre-money, that dilution lands on the founders alone and not on the incoming investor. This "option pool shuffle" quietly lowers your real pre-money, so negotiate the pool size and timing deliberately.
What Indian rules require
The number you agree is not just a handshake in India:
- For a priced round, an unlisted company issues shares by preferential allotment under Section 62(1)(c) of the Companies Act, 2013, and the price must be supported by a valuation report from an IBBI-registered valuer under Section 247.
- If any investor is resident outside India, FEMA requires the issue price to be at or above fair market value set by an internationally accepted methodology on an arm's length basis. You must allot the shares within 60 days of receiving the funds and file Form FC-GPR on the RBI FIRMS portal within 30 days of allotment.
- On tax: the "angel tax" under Section 56(2)(viib), which once taxed share premium raised above fair market value, has been abolished. The Finance (No. 2) Act, 2024 inserted a proviso so it does not apply to consideration received on or after 1 April 2025. Notices for earlier years can still arise, so keep old valuation papers safe.
Know your pre-money, your post-money and the dilution each cheque causes, and you will negotiate the ask from clarity rather than hope.
