This calculator estimates resources and currency earned while your idle game is offline. It helps gamers and game designers plan progression and balance game mechanics. Use it to account for offline caps, production rates, and potential upgrades.
Offline Earning Simulator
How to Use This Tool
Enter your character's or building's base production rate in units per second. Input the total hours you expect to be offline. Specify your current upgrade level; the tool assumes each level adds a 10% multiplier to production. Select the offline cap mechanic used by your specific game (e.g., some games limit offline earnings to 12 hours, others to 50% of online production). Finally, add an RNG variance percentage if the game includes random luck factors for offline gains.
Formula and Logic
The core calculation follows this logic:
- Base Yield: (Base Rate × Seconds Offline) × (1 + (Upgrade Level × 0.1))
- Cap Application: If a cap is selected, the Base Yield is reduced. Time caps reduce the duration used; Percentage caps reduce the total output.
- RNG Variance: The final capped value is multiplied by a random factor between (1 - Variance%) and (1 + Variance%).
Practical Notes
- Patch-Dependent Values: Game developers frequently tweak offline earning formulas in patches. Always verify the current patch notes for changes to caps or multipliers.
- Meta Variations: Some games offer "Offline Boost" items or temporary perks. Treat these as temporary upgrades to the level input.
- Performance Scaling: In games with "prestige" mechanics, your base rate might scale exponentially. Ensure you input the current visible rate, not the raw number before multipliers.
- RNG Factors: If a game guarantees a minimum offline yield (e.g., "You will always get at least 50%"), set the RNG Variance to reflect the upper bound (e.g., 50% variance means results range from 50% to 150%).
Why This Tool Is Useful
Knowing your offline earnings helps you optimize your play session timing. It prevents resource capping (wasting production) by alerting you to return before your storage fills. For game designers, it allows balancing the economy to ensure players don't lose interest during breaks. For streamers, it helps in planning "check-in" times during long broadcasts.
Frequently Asked Questions
What if my game uses a different upgrade scaling?
Our tool uses a standard 10% per level scaling. If your game uses a different curve (e.g., quadratic), simply input your effective total multiplier into the "Upgrade Level" field (e.g., if you have 2 levels but total multiplier is 2.5x, enter 2.5).
Does this account for storage limits?
No, this calculates raw production. If your storage is full, production stops. You should compare the "Total Resources" result against your maximum storage capacity to see if you will overflow.
How accurate is the RNG simulation?
The RNG feature provides a single random roll based on the variance you input. It represents a "worst-case" to "best-case" snapshot. For precise planning, consider the average (the value without RNG applied).
Additional Guidance
When using this for game design, ensure your offline cap is generous enough to reward returning after a break, but strict enough to encourage daily logins. For players, remember that offline earnings are often calculated based on server time, not local device time, so ensure your device clock is accurate if the game relies on it for initial checks.
