Valuation Cap Analysis
Startups often raise money using convertible notes or SAFEs (Simple Agreement for Future Equity). These are agreements that let investors fund a company today in exchange for equity later—usually during the next priced funding round.
One of the most important terms in these agreements is the Valuation Cap. It determines the maximum valuation at which an investor’s money converts into equity. Understanding this cap is critical for both investors and founders.
The Valuation Cap Calculator makes this process simple. By entering the cap, investment amount, and company valuation, you can instantly see how much equity you (or your investor) would receive.
What is a Valuation Cap?
A Valuation Cap sets the maximum company valuation at which convertible notes or SAFEs convert into equity.
Example:
- Startup valuation at next round: $20M
- Investor has a SAFE with a $10M valuation cap
- Their investment converts as if the valuation were $10M, giving them more shares than if it converted at $20M.
It’s a way to reward early investors for taking on higher risk.
Formula for Valuation Cap Conversion
Equity Ownership=Investment AmountValuation Cap\text{Equity Ownership} = \frac{\text{Investment Amount}}{\text{Valuation Cap}}Equity Ownership=Valuation CapInvestment Amount
For comparison, the standard conversion without a cap is: Equity Ownership=Investment AmountCompany Valuation at Round\text{Equity Ownership} = \frac{\text{Investment Amount}}{\text{Company Valuation at Round}}Equity Ownership=Company Valuation at RoundInvestment Amount
The calculator applies both formulas so you can see:
- Equity with cap
- Equity without cap
- The effective share price advantage
How to Use the Valuation Cap Calculator
Step 1: Enter Investment Details
- Investment Amount – How much is being invested.
- Valuation Cap – The agreed cap in the SAFE/note.
- Company Valuation at Next Round – The priced round valuation.
Step 2: Run Calculation
The calculator instantly shows:
- Equity % with Cap
- Equity % without Cap
- Share Price Advantage
Step 3: Compare Results
Investors can see how much extra equity they gain from the cap. Founders can see how much dilution occurs.
Practical Example
Suppose an investor puts in $100,000 into a startup with:
- Valuation Cap: $5,000,000
- Company Valuation at Series A: $10,000,000
With Cap:
Equity=100,0005,000,000=2%Equity = \frac{100,000}{5,000,000} = 2\%Equity=5,000,000100,000=2%
Without Cap:
Equity=100,00010,000,000=1%Equity = \frac{100,000}{10,000,000} = 1\%Equity=10,000,000100,000=1%
Advantage:
The investor gets 2% equity instead of 1%—effectively doubling their ownership thanks to the valuation cap.
