# What Is Price Round Math?

> Price round math is the cap table arithmetic for a priced equity financing—linking pre-money valuation, investment amount, fully diluted shares, and price per share to ownership outcomes.

**Price round math** is the set of calculations that translate term sheet economics into a pro forma cap table for a priced equity financing.

### How it works

Start with pre-money fully diluted shares—all common, preferred, options, warrants, and converting instruments. If the pool expands pre-money, increase share count before calculating [price per share](/glossary/price-per-share). Divide pre-money valuation by shares to get price; divide investment by price for new investor shares. Post-money shares equal pre-money plus new issuance; ownership is each holder's shares divided by post-money total.

Convert SAFEs and notes at their caps and discounts. Reconcile with legal's closing checklist—small rounding differences cause closing delays if not caught early.

### Why it matters

- **Founders:** Run math before accepting term sheets; negotiate pool size with full dilution visibility.
- **Investors:** Verify pro-rata investment amounts and resulting ownership match fund model assumptions.

### Common mistake

Calculating post-money ownership using pre-money share count without pool increase or SAFE conversion—everyone's percentages shift at closing.

## FAQ

### What is price round math in simple terms?

It is the spreadsheet work that connects valuation, check size, and share count to who owns what after the round—including option pool changes and note conversion.

### Why does price round math matter?

Term sheet headlines mislead without math. Founders catch pool shuffle and SAFE overhang; investors verify ownership targets before legal fees accumulate.
