- Market cap
- $42,000,000,000.00
- Book value
- $15,200,000,000.00
- P/B ratio

Formula
Price-to-Book = Market Cap / Book Value
Example
- Market cap: 42000000000
- Book value: 15200000000
What does this mean?
- •P/B above 1.0 indicates valuation above book value.
- •Capital-intensive sectors often use P/B heavily.
- •Book value quality varies by accounting assumptions and asset mix.
Compare valuation versus net asset base
Assess whether equity is priced at premium or discount to book value.
What is a price-to-book?
Use this deterministic price-to-book calculator to assess valuation relative to accounting book value. In practice, this means you can quantify price-to-book using market cap, and book value without relying on hidden assumptions or black-box scoring.
Primary input set for this calculator: Market cap, Book value.
How to calculate price-to-book
- 1.Step 1: Enter market cap with the timeframe/context you want to evaluate.
- 2.Step 2: Enter book value with the timeframe/context you want to evaluate.
- 3.Step 3: Apply formula Price-to-Book = Market Cap / Book Value.
- 4.Step 4: Interpret output together with risk, liquidity, and catalyst context.
Why this metric matters
This metric translates per-share movements into company-level value impact, improving cross-name comparability.
Pair this calculator with catalyst context from headlines, filings, and options flow to avoid relying on isolated numbers.
When to use this calculator
- ✓Before opening a new position where price-to-book impacts sizing or risk.
- ✓After a catalyst to quantify how much conditions changed versus your baseline.
- ✓When comparing setups across multiple tickers with one consistent formula.
- ✓During weekly review to keep decision-making tied to measurable inputs.

Recalculate price-to-book immediately after earnings, filings, or macro headlines.
Interpretation tips
- •Re-run price-to-book whenever key inputs change materially, not only when price moves.
- •Document assumptions so the same methodology can be repeated across watchlist names.
- •Use this metric as one layer in the decision stack, not as a standalone trade trigger.
Data caveats
- –Outputs are deterministic from your inputs; input quality determines output quality.
- –This page does not auto-adjust for broker fees, taxes, or slippage unless you include them in your assumptions.
- –Validate corporate action details, filing dates, and data freshness before acting on results.
