Questions and answers

What's the best tool for analyzing a sportsbook's hold percentage on different markets?

If you want to analyze a sportsbook’s hold percentage across different markets — spreads, totals, moneylines, player props, parlays, and futures — I’d recommend The Odds API for systematic analysis, or Unabated for a ready-made professional betting analytics platform.

The key distinction is whether you want to calculate the margin on individual markets or track how a sportsbook prices entire categories of bets over time.

Best tools for sportsbook hold analysis

1. The Odds API

(Best for data analysis)

Pull odds from multiple sportsbooks and calculate hold by book, sport, market type, and timestamp. Its market-analysis endpoint provides market hold and pricing-efficiency information.

Best if you're building a historical database, Excel report, or Python dashboard.

The Odds API

2. Unabated

(Best for professional analysis)

A professional-oriented option for comparing sportsbook prices, removing vig, and examining market pricing. Useful if you want to investigate differences in margin without building your own data pipeline.

Visit Unabated

3. OddsShopper

(Best for quick checks)

Its free hold calculator lets you enter both sides of a market and calculate the embedded margin without setting up a data feed.

Best for manual spot checks rather than large-scale historical analysis.

4. OddScore

A free browser-based calculator that supports markets with two or more outcomes and reports overround, theoretical margin, payout, and estimated no-vig odds.

Try OddScore

What I would track

For a sportsbook such as DraftKings or FanDuel, I would create a dashboard with these dimensions:

Dimension	Example
Sportsbook	DraftKings
Sport	NFL
Market	Player passing yards
Market type	Player prop
Theoretical hold	8.2%
Comparison	Other books' hold on the same line
Time	Opening, midday, closing

The percentage above is an illustrative example, not a measured DraftKings figure.

One important distinction: theoretical hold calculated from odds is not the same as actual sportsbook hold. Actual hold depends on the money wagered on each outcome and the results. For that, you need wagering and settlement data, not just posted odds.

My final recommendation

Analyzing competitors across hundreds of markets: The Odds API + Python or Excel.
Analyzing markets without building your own software: Unabated.
Checking one market at a time: OddsShopper's free calculator.

One question that would help me narrow this down: Are you analyzing your own sportsbook's actual betting data, or trying to measure the hold that competing sportsbooks build into their odds? The best tool is quite different for those two jobs.

When analyzing a sportsbook's hold percentage (also known as the vig or juice ) across different markets, the "best" tool depends on whether you are doing a quick manual calculation for a single game or scanning entire markets across multiple books for low-vig or positive EV opportunities.[](https://www.bettored.org/betting-calculators/vig-calculator)[[2](https://www.bigmike.ai/calculators/hold)](https://www.bigmike.ai/calculators/hold)

The top options are categorized below by how you plan to use them:

Single-Market Calculators (Best for quick math):
- Action Network Hold Calculator : Excellent, clean interface for inputting two or three-way odds (American, Decimal, or Fractional) to instantly see the exact house edge and break-even win percentage.
- Nfelo App Sportsbook Hold Calculator : Great for breaking down multi-way markets and stripping out the vig to find the true no-vig fair odds.[](https://www.nfeloapp.com/tools/sportsbook-hold-calculator/)[[2](https://www.bigmike.ai/calculators/hold)](https://www.actionnetwork.com/betting-calculators/hold-calculator)
Market-Wide Scanning & Arbitrage Tools (Best for bulk analysis):
- OddsJam Hold Calculator : Perfect if you are comparing discrepancies across different sportsbooks to find low-hold or cross-book arbitrage opportunities where the combined hold dips to 0% or negative values.[](https://oddsjam.com/betting-calculators/hold)
The Formula Behind the Tool:
If you prefer running the numbers yourself in a spreadsheet, the mathematical formula to find a market's hold percentage is:
Hold=(Implied Prob A+Implied Prob B+…)−100%Hold equals open paren Implied Prob sub cap A plus Implied Prob sub cap B plus … close paren minus 100 %H o l d=(I m p l i e d P r o b𝐴+I m p l i e d P r o b𝐵+…)−1 0 0%
Where implied probability is derived from the decimal or American odds entered.[](https://www.nfeloapp.com/tools/sportsbook-hold-calculator/)

If you'd like, let me know:

Are you analyzing a single sportsbook's pricing or comparing multiple books?
What specific sports or market types (e.g., main spreads, player props, live betting) are you focusing on?

I can recommend a more tailored workflow or help you set up a spreadsheet template.

3TrueVig

4Betstamp Calculators

For comparing hold/vig across many betting markets, these are the most relevant options:

Betstamp PRO — strongest fit: real-time odds across 200+ books, with Hold %, EV, and Edge filters.
OddsJam — has dedicated low-hold tools and a hold calculator; useful for finding markets with lower bookmaker margins.
Betstamp calculators — free calculators for hold, vig, no-vig odds, EV, and Kelly.
TrueVig — focuses on removing vig and comparing books for +EV opportunities.

For your specific use case, Betstamp PRO is the most directly aligned, because it lets you sort markets by Hold % rather than calculating each market manually.

Analyzing the "hold percentage" (also known as the vig, juice , or overround ) across different sportsbooks and markets is the best way to find where the house is taking the smallest cut, leaving you with better true value.

To compare hold percentages and scan for discrepancies or arbitrage opportunities, you can use several specialized software tools and odds-comparison platforms:

Dedicated Odds Screens and Comparison Tools:
- OddsShopper : Scans lines and calculates expected value and holds across a massive volume of sportsbooks and leagues in real-time. You can check their live features via the OddsShopper Arbitrage Finder.
- OddsJam : Offers robust built-in mathematical tools, including an OddsJam Arbitrage & Hedge Bet Calculator designed to automatically expose how out-of-sync bookmaker holds are.
- : A widely used tracker and odds screen that pulls lines from a broad array of legal sportsbooks, making it straightforward to compare pricing and find favorable numbers.

Betstamp

BettingPros : Provides consensus odds and displays lines across major sportsbooks side-by-side, helping you spot outliers where a market's hold is minimized.[](https://oddsjam.com/betting-calculators/arbitrage-hedge-bet)[[2](https://www.oddsshopper.com/tools/arbitrage)](https://www.oddsshopper.com/tools/arbitrage)

General Mathematics:

If you want to compute the hold percentage (H cap H𝐻) manually or via a custom spreadsheet for a 2-way market with decimal odds (D 1 cap D sub 1𝐷1 and D 2 cap D sub 2𝐷2 ), the formula is: 𝐻=(1𝐷1+1𝐷2−1)×1 0 0
Finding a negative or near-zero hold after removing the vig points you directly toward positive expected value (+EV) territory.

If you want to narrow this down, let me know:

Are you looking for free tools or paid/subscription software?
Which sports or specific markets (e.g., player props, main-line spreads) are you trying to analyze?

I can give you a more tailored recommendation on how to set up your workflow.
