The Steam Game Value Calculator helps gamers determine the actual cost per hour of entertainment from their game library, enabling rational purchasing decisions and library management. The core metric is Cost Per Hour (CPH), calculated by dividing the amount paid for a game by total hours played. A game purchased for $60 that you play for 10 hours costs $6 per hour of entertainment — more expensive than most streaming services but comparable to a movie ticket. A game purchased on sale for $5 that you play for 200 hours costs $0.025 per hour — exceptional value by any metric. This analysis reveals that conventional 'game value' discourse (AAA games being too expensive) often misses the core calculation: hour-count matters far more than price. A $70 RPG played for 100 hours ($0.70/hr) is a better value than a $20 indie game played for 5 hours ($4/hr). Steam's library shows your actual playtime, allowing precise CPH calculations. The gaming industry average suggests players spend approximately 18-22 hours per game across their libraries. However, this average is skewed by the many purchased-but-never-played games (a phenomenon so common Valve introduced the concept of 'discovered' vs 'purchased' games). The true calculation for a library is: Total Value = Sum(game_price / hours_played) only for games played more than 1 hour. Unplayed games represent pure sunk cost. The CPH framework also helps evaluate subscription services like Xbox Game Pass and PlayStation Now — dividing monthly cost by hours played that month gives the subscription's effective CPH, often making it the best value for high-volume gamers.
Cost Per Hour = Purchase Price / Hours Played Library Efficiency = Total Spent on Played Games / Total Hours Across Library Game Pass Value CPH = Monthly Subscription Cost / Hours Played Per Month
- 1Step 1: Find your purchase price from Steam receipts or the Steam database.
- 2Step 2: Check hours played on your Steam profile or in-game.
- 3Step 3: Divide purchase price by hours played for CPH.
- 4Step 4: Compare CPH to benchmark: movies (~$1.50/hr), streaming (~$0.50/hr), live events ($5-50/hr).
- 5Step 5: Apply to unplayed games to identify poor investments worth gifting or trading.
- 6Step 6: Use CPH analysis to evaluate future purchases at current vs. sale prices.
Stardew Valley at $14.99 and 320 hours represents one of the best gaming investments available. At under 5 cents per hour, it beats the entertainment value of virtually every other form of paid entertainment. This type of game — deeply replayable with procedural content or emergent gameplay — routinely delivers 100-1000 hour libraries for single-digit dollar purchases on sale.
A $70 AAA game played for only 25 hours delivers $2.80 per hour — comparable to watching a movie. This is not inherently bad value; movies at $15 for 2 hours cost $7.50 per hour. However, if the same game is purchased on a 50% sale ($35) and played for 60 hours as content updates release, the CPH drops to $0.58 — excellent value. Waiting for sales dramatically improves CPH on linear or completable games.
Steam libraries often contain hundreds of never-played games from Humble Bundles, gift purchases, and sale impulse buys. From a value perspective, these represent pure lost money. The healthier approach is tracking CPH before purchasing and only buying games you plan to play within the next 30 days, rather than stockpiling a backlog that grows faster than your available gaming time.
Playing 40 hours across 3 Game Pass games in a month means an effective CPH of $0.375 — exceptional. If you played those same 3 games at $30 average purchase price ($90 total), the CPH would be $90/40 = $2.25. Game Pass provides the best value for players who sample many titles without committing to long playthroughs of each, and for players in regions where the monthly cost is a smaller fraction of disposable income.

Games as a Service (GaaS)
{'title': 'Games as a Service (GaaS)', 'body': 'Live service games (Fortnite, Apex Legends, Genshin Impact) are often free to download but monetize through cosmetics and battle passes. CPH calculations must include all in-app purchases made. A player spending $100/month on Fortnite cosmetics who plays 50 hours has a $2/hr effective CPH.'}
Multiplayer and Social Value
{'title': 'Multiplayer and Social Value', 'body': 'Games played with friends add social value beyond pure entertainment cost. A $60 game played for only 20 hours with 3 friends ($3/hr) may provide more total value than a $20 single-player game played alone for 100 hours ($0.20/hr), because social experiences have intrinsic value beyond pure entertainment duration.'}
When using the Steam Game Value for comparative steam game value analysis
When using the Steam Game Value for comparative steam game value analysis across scenarios, consistent input measurement methodology is essential. Variations in how steam game value inputs are measured, estimated, or rounded introduce systematic biases compounding through the calculation. For meaningful steam game value comparisons, establish standardized measurement protocols, document assumptions, and consider whether result differences reflect genuine variations or measurement artifacts. Cross-validation against independent data sources strengthens confidence in comparative findings.
| Entertainment Type | Cost per Hour | Notes |
|---|---|---|
| Netflix (basic) | $0.15-0.30/hr | Varies by watch frequency |
| Movie (cinema) | $4.50-8.00/hr | Includes 2hr avg runtime |
| Video game (average) | $0.50-2.00/hr | Varies widely by title |
| Book (paperback) | $0.50-1.00/hr | Assuming 10hr read time |
| Live concert | $10-50+/hr | Premium experience |
| Theme park | $8-15/hr | Full day admission |
What is a good cost per hour for a video game?
There is no universal standard, but common benchmarks: streaming services cost approximately $0.20-0.50 per hour of content; movies cost $1.50-8.00 per hour (depending on cinema vs streaming); live sports/concerts cost $5-50+ per hour. Games below $1 per hour are generally considered excellent value; $1-3 per hour is acceptable; above $5 per hour suggests the game was not a good fit for your play style or should have been left on wishlist for a sale.
Should I use original price or sale price in the calculation?
Use the price you actually paid. The original retail price is irrelevant to your personal value calculation — if you paid $5 during a sale, your investment is $5 regardless of the $60 MSRP. Some players prefer tracking both: using MSRP shows you the game's 'theoretical maximum CPH' before any discounts, which helps evaluate whether to buy now at full price or wait for a sale.
Does Steam track all game hours accurately?
Steam tracks hours when the game is running through the Steam client but misses time played offline (when Steam is in offline mode) and time in non-Steam games added to the library. Hours can also be artificially inflated by leaving a game running idle (AFK hours) or deflated for games launched via third-party launchers like Epic, GOG, or EA App. The tracking is good enough for broad value assessments but not perfectly precise.
How does the Steam sale cycle work for maximum value?
Steam runs major sales at predictable times: Summer Sale (late June), Autumn Sale (late November), Winter Sale (late December), and Spring Sale (March). Many games hit their historical lowest prices during these events. The Steam Database site (SteamDB) tracks price history for every game, showing the all-time low price and when it occurred. Checking SteamDB before purchasing reveals whether the current price is genuinely discounted or simply the normal price.
Is a game with 1000 hours necessarily a good investment?
Not necessarily — consider opportunity cost. 1000 hours represents 125 eight-hour days of gaming. If you paid $30 for the game, the CPH is excellent at $0.03. But were those 1000 hours genuinely enjoyable, or were you grinding repetitively past the point of enjoyment? CPH measures entertainment cost, not entertainment quality. A 50-hour game at $1/hr that you loved may represent better life value than 1000 hours at $0.03/hr of a game that became a habit rather than a pleasure.
How should I evaluate my existing library?
Export your Steam library data using SteamDB or the official Steam API. Calculate CPH for every game with more than 1 hour played. Games above $5/hr that you are no longer playing represent poor value decisions — understand what happened (poor game fit, bought at wrong time, incomplete) to improve future purchasing choices. Games below $1/hr indicate your high-value genres and play styles to seek out for future purchases.
Does refund policy affect value calculations?
Steam's refund policy (within 14 days and under 2 hours of play) effectively allows you to 'try' any game and return it if it doesn't click. This policy makes short-trial games low-risk: if you play for 1.9 hours and decide it's not for you, refunding resets your CPH calculation to zero. Players should exploit this policy actively for games they are unsure about rather than letting them sit unplayed in the library.
プロのヒント
Before any game purchase, calculate the CPH at its current price assuming you play it for your 'average game completion time' for similar genres. If the CPH is above your personal threshold, wait for a sale or move the game to your wishlist for Autumn/Winter sales.
ご存知でしたか？
PlayerUnknown's Battlegrounds (PUBG) players average over 400 hours per account in Steam statistics — one of the highest in any game. At the current $30 price, early adopters who paid $30 at launch and played 400 hours have a CPH of approximately $0.075 — less than 8 cents per hour.
