This tool calculates offline resource earnings for idle and incremental video games. It helps gamers, game designers, and streamers estimate progress when away from active play. Use it to plan resource gains between sessions or balance game economy tuning.
Resources earned when game is active, before multipliers
Total time away from the game
Global or event multiplier applied to offline earnings
đź’ˇ Tip: Check your game's settings for base offline rates and active multipliers before calculating.
How to Use This Tool
Follow these steps to calculate your idle game offline earnings accurately:
- Locate your base offline earning rate in your game’s settings or stats menu. Enter this value in the Base Offline Earning Rate field, and select the correct time unit (per second, per minute, or per hour).
- Enter the total time you were offline in the Offline Duration field, and select the matching unit (minutes, hours, or days).
- Select your active earning multiplier from the dropdown. If you have a custom multiplier (e.g., from a limited-time event or purchased boost), select Custom Multiplier and enter the value.
- Click the Calculate Earnings button to see your full earnings breakdown. Use the Reset Form button to clear all inputs and start over.
- Use the Copy Results button to save your earnings summary to your clipboard for reference.
Formula and Logic
The calculator uses a three-step process to compute offline earnings, adjusting for time units and multipliers:
- Convert base earning rate to resources per hour:
- Per second rate Ă— 3600 = per hour rate
- Per minute rate Ă— 60 = per hour rate
- Per hour rate remains unchanged
- Convert offline duration to hours:
- Minutes Ă· 60 = hours
- Hours remain unchanged
- Days Ă— 24 = hours
- Calculate total earnings:
- Base Earnings = Rate per hour Ă— Duration in hours
- Total Earnings = Base Earnings Ă— Multiplier
- Effective Hourly Rate = Rate per hour Ă— Multiplier
All values are rounded to two decimal places for readability. Multipliers are applied after converting all values to hourly units to ensure consistency.
Practical Notes
Idle game economies vary widely between titles, so keep these game-specific factors in mind when using this tool:
- Many idle games cap offline earnings at a maximum duration (e.g., 24 hours of offline progress). Check your game’s rules to ensure your entered duration does not exceed this cap.
- Multipliers and base rates are often patch-dependent: developers may adjust values in updates, so always use the most recent in-game numbers.
- Some games include RNG (random number generator) elements or diminishing returns that affect actual earnings. This tool calculates deterministic values, so in-game results may vary slightly.
- Performance scaling: Games with prestige or reset systems have higher base rates after resetting. Update your base rate input after each prestige to keep calculations accurate.
- Event multipliers are often temporary: Only apply event boosts for the duration they were active, not your entire offline period.
Why This Tool Is Useful
This calculator serves multiple use cases for different gaming audiences:
- For casual gamers: Plan resource gains between play sessions to hit progression milestones faster.
- For game designers: Balance offline economy tuning by testing how different multipliers and base rates affect player progression.
- For streamers: Estimate earnings to share progress updates with viewers, or plan offline streaming breaks without losing track of in-game gains.
- For competitive players: Optimize boost usage by calculating which multiplier and duration combinations yield the highest returns.
Frequently Asked Questions
Why do my actual in-game earnings differ from the calculator’s results?
Most idle games include RNG elements, offline earning caps, or diminishing returns that this deterministic tool does not account for. Check your game’s specific offline rules to adjust inputs accordingly.
Can I use this tool for games with prestige or reset systems?
Yes, but you must update the base offline earning rate input each time you prestige, as base rates typically increase after resetting your progress. Enter the post-prestige base rate for accurate calculations.
How do I find my base offline earning rate?
Check your game’s stats menu, settings, or upgrade panel. Most idle games display your current resource gain rate per second/minute/hour, which is your base rate before multipliers.
Additional Guidance
To get the most accurate results, follow these best practices:
- Always use in-game values from the same session: Base rates and multipliers can change between play sessions due to upgrades or events.
- Split calculations for mixed periods: If you had a 2x event active for 4 hours of your 8-hour offline period, run two separate calculations (4 hours at 2x, 4 hours at 1x) and add the results.
- Test edge cases: If you’re a game designer, use this tool to simulate how changes to base rates or multipliers affect player progression over 1 day, 1 week, or 1 month of offline time.
- Keep a log of calculations: Save your results with the copy function to track how your earnings change as you progress through the game.
