Upgrade Cost Calculator
Estimate expected cost, average attempts and cumulative success chance for upgrade systems.
Use this upgrade cost calculator to estimate how many resources an enhancement may consume before it lands. It works well for games with gear upgrades, enchanting, crafting, refining, forging and any system where each try has its own success percentage.
Enter the cost per attempt, the success rate and how many tries you plan to make. The tool returns the expected cost until the first success, the average number of attempts, the average failures before success, the cumulative chance of succeeding within your plan and the total amount you intend to spend.
That makes it easier to compare strategies, manage risk and decide whether it is worth pushing now or saving more resources first. It is a fast planning tool for anyone who wants cleaner upgrade math without building a spreadsheet.
Use clear inputs to get a more useful result.
How to use Upgrade Cost Calculator
Open the tool, fill in the fields with the data you already have and generate the result step by step. If you want to compare scenarios, change one field at a time so it is easier to understand the impact of each value.
