# Quick Start Guide
The biggest advantage of the post-money SAFE is that the amount of ownership sold is immediately transparent and calculable for both the founder and the investor. This Quick Start Guide will show how to take advantage of this structure for the most common use cases.
> **Note:** In the examples below, if the valuation in the round in which the SAFE converts is less than the Post-Money Valuation Cap (or too close to it), the SAFEs may convert into more than the estimated ownership. See the Q&A section in the User Guide.
## 1. Raising money with a single Post-Money Valuation Cap
A founder is targeting a $6.7 million post-money valuation.
> “I’m targeting $6.7 million post / $6.7 million.”
If the founder raises:
- $800k → Ownership sold = `0.8 / 6.7 ≈ 12%`
- $1 million → Ownership sold = `1.0 / 6.7 ≈ 15%`
## 2. Raising money with multiple Post-Money Valuation Caps
A founder is targeting a $5.5 million post-money valuation, with multiple caps.
- **Post-Money Valuation Cap #1:** $5.5 million → Ownership sold ≈ 9%
- **Post-Money Valuation Cap #2:** $8.3 million → Ownership sold ≈ 6%
## 3. Estimating the dilutive impact of pro-rata rights
SAFE holders with pro-rata rights can subscribe for a percentage of the total Equity Financing equal to their “as-converted” ownership. You can back-solve dilution using:
`
Safe Pro-Rata Allocation % = Series A New Investors % / (100% - Safes with Pro Rata %)
`
### Example
**SAFE fundraise**
Company sold 15% of the company pre-Series A via SAFEs ($5 million post-money cap)
Every SAFE investor received a pro-rata side letter
Company issued 8% of the company pre-Series A in options
**Series A assumptions**
- Lead & new investors will own 25% post-Series A (excluding SAFE pro-rata)
- Option pool increased to 10% unissued & available post-Series A
#### Step-by-step calculation
`
Safe Pro-Rata Allocation %
= 25% / (100% - 15%) - 25%
= 4.41%
`
`
Combined Series A + SAFE pro-rata
= 25% + 4.41%
= 29.41%
`
**Total dilution**
`
Series A investments + options pool
= 29.41% + 10%
= 39.41%
`
**Dilution breakdown**
- SAFE dilution: `15% x (100% - 39.41%) = 9.09%`
- Options dilution: `8% x (100% - 9.09% - 39.41%) = 4.12%`
- Series A dilution: `39.41%`
**Total dilution:** `9.09% + 4.12% + 39.41% = 52.62%`
> Note 1: The 8% in options issued between the SAFEs and Series A are diluted by both SAFEs and the Series A terms.
>
> Note 2: SAFE ownership is post-SAFEs but pre-Series A. SAFEs act as their own round and are diluted by the subsequent Series A round.
