Closing Line Value (CLV) Calculator: Did Your Bet Beat the Closing Line?
Closing Line Value (CLV) measures whether the line or odds you bet were better than the final consensus market line at tip-off or kickoff. For point spreads and game totals, Point CLV = Closing Line − Bet Line (signed in your bet's favor: Bet Spread − Closing Spread for spreads, Closing Total − Bet Total for Overs, and Bet Total − Closing Total for Unders); for odds, No-Vig EV% = (True Closing Win Probability × Decimal Payout) − 1. Every official 1.5u Lock and 1.0u Like on nbapicks.live/record is permanently frozen at tip-off and graded against the closing line. 21+ only. No pick is ever guaranteed.

Exact Closing Line Value (CLV) & No-Vig Expected Value Formulas
Spread CLV = Bet Spread − Closing Spread
Betting a favorite at CLE -4.5 that closes CLE -5.5 yields -4.5 − (-5.5) = +1.0 pt of CLV. Betting an underdog at +4.5 that closes +3.0 yields +4.5 − 3.0 = +1.5 pts of CLV.
Over CLV = Close − Bet · Under CLV = Bet − Close
Betting Over 224.5 that closes 227.0 yields +2.5 pts of CLV. Betting Under 228.5 that closes 226.0 yields +2.5 pts of CLV.
p_true = p1 / (p1 + p2) · EV% = (p_true × Dec) − 1
Removing the sportsbook hold isolates the market's true closing win probability. At standard -110 odds (1.9091x decimal), your break-even win rate is 52.38%.
Which Closing Line Should You Grade CLV Against? Same-Book Close vs. Market Consensus
To measure true Closing Line Value (CLV), grade bets against a market-wide close, not one soft retail book's close. Our desk freezes every NBA play at tip-off and grades it against the Vegas consensus close captured in the final 15 minutes before tip, at the logged or stored closing price (/record). 21+ only. No pick is ever guaranteed.
| Benchmark Type | How It Works | Pros | Cons / Manipulation Risk | How Our Desk Uses It |
|---|---|---|---|---|
Same-Book Retail Close e.g., grading a DraftKings bet only vs. DraftKings' close | Compares your ticket strictly against the final number at the exact retail book where you placed it. | Shows whether you timed that specific book's line move well. | Soft books shade lines to balance recreational liability or lag sharp injury moves, creating “phantom CLV” when the wider market didn't move. | Not used for official record grading. |
Single Sharp Book No-Vig Close e.g., Pinnacle or Circa, vig removed | Uses the highest-limit market-making book's final line and removes the vig to find the true closing win probability. | Highest price-discovery efficiency on sides and totals. | Can briefly skew on isolated limit tests right before tip-off. | Not stored or used for grading. Supported in /clv-calculator through the Close Odds (Your Side) / (Opp Side) no-vig inputs. |
Vegas Market Consensus Close our official grading standard | The pre-tip read (inside the final 15 minutes before tip-off) of the VSIN Vegas consensus spread and total. When no consensus number is posted, a single major book (DraftKings first) or ESPN's line; when no pre-tip read landed, ESPN's posted close. | Avoids single-book outliers and stops anyone from shopping a stale rogue line to manufacture wins. | The fallback can be one book's number, and a consensus price isn't always posted, so payouts use the logged price, else the stored closing price, else standard -110. | Official standard on /record: frozen in PostgreSQL at tip-off and never overwritten; audited via Veri.bet, TrustMyRecord, War Room Picks, and /api/pickauditor-feed. |
Closes captured before Oct 30, 2026 came from the DraftKings line via ESPN.
Frequently Asked Questions · Closing Line Value (CLV) Calculator
How do you calculate Closing Line Value (CLV) on a point spread or game total?
For point spreads, Spread CLV = Bet Spread − Closing Spread (for example, betting CLE -4.5 when the game closes CLE -5.5 gives -4.5 − (-5.5) = +1.0 point of CLV; betting +4.5 when it closes +3.0 gives +1.5 points of CLV). For game totals, Over CLV = Closing Total − Bet Total (betting Over 224.5 that closes 227.0 = +2.5 pts CLV) and Under CLV = Bet Total − Closing Total (betting Under 228.5 that closes 226.0 = +2.5 pts CLV).
How do you remove sportsbook vig (hold) to find true closing probability and EV%?
First convert both sides of the closing American odds into raw implied probabilities (p1 and p2). The bookmaker hold is (p1 + p2) − 1. Divide your side's raw implied probability by the sum of both sides to get the vig-free closing win probability: p_true = p1 / (p1 + p2). Then multiply p_true by the decimal payout of the odds you bet and subtract 1: No-Vig EV% = ((p_true × DecimalOdds_bet) − 1) × 100.
Why do sharp bettors and third-party auditors grade picks against the closing line?
The consensus closing line at tip-off incorporates every public and institutional dollar, injury report, and rest adjustment in the market. Consistently beating the closing line (positive CLV) is the strongest mathematical indicator of long-term positive expected value, whereas grading picks against stale early-week lines allows touts to claim phantom edges that were already gone before game time.
Does positive Closing Line Value guarantee that a bet will win?
No. Beating the closing line by +1.0 to +2.5 points shifts your expected win probability into profitable territory (55%–60%+ over a full season), but single-game NBA shooting variance means positive-CLV bets still lose regularly. That is why every official 1.5u Lock and 1.0u Like on nbapicks.live/record is permanently frozen at tip-off with every win, loss, and push included.
Which closing line does your desk use to grade picks and calculate CLV?
Every NBA pick is graded against the closing number our odds feed captures in the final 15 minutes before tip-off: the VSIN Vegas consensus line, or a single major book (DraftKings first) or ESPN's line when no consensus number is posted, and ESPN's posted close if no pre-tip read landed. That close is frozen in PostgreSQL and never overwritten. Results are paid at the price logged with the pick, else the stored closing price for that side, else standard -110. CLV is the published release line versus that close, and shows as not tracked when no release line was recorded. In our /clv-calculator you can also enter any sharp book's two-way closing odds (such as -105 / -115) to remove the vig and calculate true closing win probability and EV%.
