How is crit factored into the DPS?

Crit is averaged probabilistically. The expected damage multiplier per hit is 1 − critChance + critChance × critMultiplier, so a 20% chance at 2x gives an average multiplier of 1.2. This avoids overstating DPS by assuming every hit crits.

Are buffs additive or multiplicative here?

The damage buff is applied additively to the base hit (base × (1 + buff%)), then the crit multiplier and attack speed are applied multiplicatively. Enter a single combined buff percentage if you have several additive buffs.

What does hit rate change?

Hit rate scales how many of your swings actually connect. At 85% hit rate, only 85% of your attacks-per-second land, so your effective DPS is reduced proportionally to reflect missed or whiffed swings.

What is the crit contribution figure for?

It shows how much of your total DPS comes purely from crits, by comparing your DPS to a no-crit baseline. It helps you decide whether investing in more crit chance or crit multiplier is worthwhile for your build.

Is this the exact Elden Ring damage formula?

It models the parts you control for comparing builds — base hit, buffs, crit, attack speed, and accuracy. It does not include enemy defence, poise, or stagger, which are target-specific. For relative build comparison it is accurate.

Elden Ring DPS Calculator

This calculator gives you a realistic average damage-per-second figure for an Elden Ring build by combining your hit damage, buffs, crit profile, attack speed, and accuracy — using proper probabilistic crit averaging rather than assuming every hit lands a critical.

How it works

DPS is built up in clear multiplicative steps:

Buffed hit. Start from your base hit and apply the damage buff additively: base × (1 + buff%).
Average crit multiplier. Instead of assuming every hit crits, the tool uses the expected multiplier 1 − critChance + critChance × critMultiplier. A 20% chance at 2x crit gives an average multiplier of 1.2.
Hits per second. Multiply attacks per second by hit rate to get the number of hits that actually land each second.
DPS. Multiply the effective per-hit damage by landed hits per second.

DPS = base × (1 + buff%) × avgCritMult × attacksPerSec × hitRate

Worked example

A weapon dealing 520 per hit, with a 15% buff, 20% crit chance at 2x, swinging 1.4 times a second, landing 85% of swings:

Buffed hit      = 520 × 1.15 = 598
Avg crit mult   = 1 - 0.20 + 0.20 × 2 = 1.20
Effective hit   = 598 × 1.20 ≈ 717.6
Hits per second = 1.4 × 0.85 = 1.19
DPS             ≈ 717.6 × 1.19 ≈ 854

The crit contribution line then shows how much of that 854 comes from crits alone.

Tips and notes

To compare two builds fairly, keep hit rate and attack speed consistent and only change the gear stats you are testing.
Investing in crit only pays off when both crit chance and crit multiplier are high — watch the crit-contribution figure to judge the trade-off.
Enemy defence and poise are not included, since they are target-specific; this tool is for relative build comparison. Everything runs locally in your browser.
