How is the number of attempts to reach a level estimated?

Each enchant attempt is an independent trial with a success probability p. The expected number of attempts to succeed once is 1 divided by p. The tool sums that figure across every level step on the way to your target.

Why does each level cost more attempts than the last?

Success probability falls as the enchant level rises, so the expected attempts (1 divided by p) climb steeply. Going from level 8 to 9 can take many times more tries than the early levels even though it is a single step.

What does the item tier change?

Higher tiers start from a lower base success rate, so every level step is harder. The tool scales the base probability down by tier so a high-tier item realistically needs far more attempts and material.

Is this the exact in-game rate?

It uses a transparent declining-probability model that matches the feel of CS2 enchanting. Treat the result as a planning estimate; real runs vary because each attempt is random and you can get lucky or unlucky streaks.

Does failure reset my level?

This model assumes a failed attempt simply does not advance the level, which is the most common upgrade rule. If your server uses a downgrade-on-failure rule, the real cost will be somewhat higher than shown.

Enchanting gear in CS2 gets punishingly expensive at high levels because each attempt succeeds less often than the last. This calculator turns the per-level success rates into an expected number of attempts and a total cost, so you can decide whether that next gear-score push is worth the materials.

How it works

Each enchant attempt is an independent Bernoulli trial. If the success probability at a level is p, the expected number of attempts to advance one level is 1 / p. To reach a target level you sum that across every step:

p(level)        = baseRate × tierFactor × declinePerLevel^level
expectedAttempts = Σ over each level step of 1 / p(level)
totalCost        = expectedAttempts × costPerAttempt

Because p shrinks geometrically with level, the 1 / p terms grow quickly, which is why the last couple of levels dominate the total cost.

Example and tips

Pushing a mid-tier item from level 6 to level 9 might need roughly 4 attempts for level 7, around 8 for level 8, and well over 15 for level 9 — so most of your budget goes to that final level. If a target level shows a huge expected attempt count, it is usually cheaper to buy or trade for the item than to grind it, or to stop one level short where the gear-score gain per material spent is best.
