How to calculate the most optimal upgrade

AI Overview

Calculating the best upgrade in any game relies on maximizing the
marginal utility (value gained) per unit of cost (resources spent). The most effective, generally applicable formula is to compare the cost of an upgrade against the speed at which it pays for itself—often called Return on Investment (ROI) or Cost Efficiency.

Here is how to calculate the best upgrade "right now": 
1. The Core Formula: Efficiency = Gain / Cost

Instead of looking at the total power, focus on the increase in power relative to the price.

• Best Upgrade =
  Projected Increase in OutputCost of Upgradethe fraction with numerator Projected Increase in Output and denominator Cost of Upgrade end-fraction

  Projected Increase in OutputCost of Upgrade

• Example (Incremental Games): If an upgrade costs 100 coins and increases your income by 10 per second, its efficiency is

• 10/100=0.110 / 100 equals 0.1

  10/100=0.1
  If another upgrade costs 500 coins but adds 100 per second, its efficiency is

  100/500=0.2100 / 500 equals 0.2

  100/500=0.2

  . The second upgrade is better.

2. The Step-by-Step Evaluation Process

1. Identify Bottlenecks: Look at your current stats, performance, or resource income. What is slowing you down?

   • Examples: Slow FPS (GPU/CPU bottleneck), low damage (Weapon upgrade), slow resource accumulation (Production upgrade).

2. Calculate Marginal Utility: How much better will I be after the upgrade?

   • 

     New Value−Old Value=Marginal IncreaseNew Value minus Old Value equals Marginal Increase

     New Value−Old Value=Marginal Increase

     .

3. Evaluate Cost: How many resources (gold, time, XP) will I spend?

4. Prioritize Global Buffs: If the game offers upgrades that affect all units/skills rather than one, these are almost always the best choice.

5. Factor in Time/Cost Efficiency: If the upgrade cost is exponential (e.g.

   

   1.3×1.3 cross

   1.3×

   previous cost), an upgrade that takes too long to pay for itself is a bad investment, even if it adds power. Reddit +4

3. Application to Different Game Genres

• Idle/Clicker Games: Use the "ROI" method. Calculate the time to regain the cost:

  

  Cost/Additional Income per secondCost / Additional Income per second

  Cost/Additional Income per second

  . The lowest time wins.

• RPG/MMORPGs: Look for the biggest percentage increase to your primary stat. An item with +10% Crit Chance is better than +50 Raw Damage if your crit chance is low, but worse if you have 90% crit chance already (diminishing returns).

• PC/Hardware Upgrade: Check Task Manager. If GPU usage is 100% while gaming, get a GPU. If CPU is 100% and GPU is low, upgrade the CPU.

• Survival/Base Builders: Prioritize upgrades that reduce resource costs first (cheaper to upgrade later), then speed up production, then combat power. Reddit +4

Summary Rule

If an upgrade provides a high percentage gain for a low relative cost, it is the best upgrade to get right now.
