Chambers of Xeric Loot Calculator

🏰 Chambers of Xeric Loot Calculator

Estimate CoX loot value from team points, personal points, death and supply penalties, Challenge Mode settings, purple split rules, and expected common loot.

Tip: Treat this as a loot-value planner, not a target-drop dry calculator. Team points drive purple frequency; personal points and split rules decide what that purple is worth to you.

⚙️Loot Value Inputs
Calculator note: Defaults use the common CoX point rule of one unique roll per 867,500 team points. GP values are editable because exchange prices and split rules change.
Normal raids use point-based uniques and standard common loot planning.
Equal split uses team purple odds; FFA and iron use your personal point claim.
Actual raiders receiving points from the chest.
For a 3+8, enter 11 as the displayed scale and 3 as eligible players.
Used for the raid-wide purple chance before the penalty model is applied.
Your share of the chest and common loot estimate starts here.
Modeled as a 40% personal-point loss per death, compounding across deaths.
Use for scavenger supplies, prep drain, or any point reduction you want to reserve.
Optional team-wide penalty for other deaths, disconnects, or low-value points.
Editable GP estimate for herbs, seeds, ores, runes, and supplies from normal loot.
Use your own table average, split sheet average, or target raid-night estimate.
Equal split divides purple value by this count. FFA ignores this field.
Subtract potions, food, charges, and scouting expenses from loot EV.
Include scouting, banking, prep, Olm, and split handling time.

Tip: A split raid can be worth more per hour than an FFA raid even when your personal purple-in-name chance is lower, because every team purple contributes to your expected payout.

Common loot is modeled separately because it generally follows your personal contribution rather than team split rules.

Challenge Mode has separate cosmetic motivations, so this calculator keeps the main GP model focused on common loot, purples, penalties, and time.

Tip: For a realistic raid-night estimate, set purple value from your team's split sheet average and common GP per 1,000 points from your own loot tracker sample.

When you begin the raid, you’re thinking about your prayer pots and Olm’s phase transitions. Three hours later, when the loot window pops up, all that math about how much gold per hour come to mind.

Time is the true currency here so most players end up losing “money”. Which is to say, they waste time, during this gap between expectation and reality.

How to Calculate Your Raid Profit

Once you input your team’s performance into the calculator above, it do the raw arithmetic for you. It spares you the guesswork of wondering whether you had an entertaining but ultimately costly run or one so chaotic it result in actual profit.

This comes back to the point system and its role in dictating value. Namely, what your team’s proximity to eighty-sixty-seven-thousand-five-hundred is on any given unique roll. Players knows that higher means more chance at loot. What many don’t realize is how fast their points will be lost under penalty.

Taking a death doesn’t only subtract what you contributed; it multiplies into a massive cut in your portion. The tool models it as 40% cut per death. It is a cruel multiplier that can make even a good run into a net negative experience when trying to go it alone or guide an uncoordinated party.

This is where many fail to see the logic. They forget that whole reason to survive Olm is precisely the economic plan. There’s one more wrinkle that simple average can’t convey: splitting up the catch.

Equal-split mode means that as a player, your individual points counts less. What matters now is the combined power of the squad. That changes everything in terms off risk profile. Maybe you’re hauling gear, and not putting down as many points. Or maybe something is going wonky and it’s just not your day. Regardless, you’ll get a little bit of whatever a team bag drops. And the calculator accounts for the number of players taking a cut out of the bag.

So, for example, a steady trio run tend to be far more efficient (in terms of expected value) compared to a high variance solo run. Even though the total possible payout may appear smaller in theory. Grinding is about dependable income (and stability trumps spikes).

The reason we don’t talk about common loot as much is that it’s boring, especially when compared to the glitz and glamor of purples. Common stuff like herbs, ore, runes, and seeds accumulate over time. They’ll pad your wallet ever-so-slowly, but no one cares until they gets the next rare item.

The page has a reference table that shows how many points are worth how much gold if you change the number of gold/point to reflect your own personal experience. Why? Two people can have the same amount of points but end up with very different results at the end of the day. That depends on selling/banking strategy, inventory management, etc. No one knows your numbers as well than you do, so use that instead of some general guess.

In Challenge Mode, however, time becomes the main cost. While points is still linked to their special rolls, the reset time extends and the challenge itself grows more difficult. That’s why the calculator also considers how long your raid will take. That has a direct effect on “earnings per hour” number.

If you’re getting lots of points from a slower run, then you may see some big numbers in terms of total gold. However, those numbers will often fall flat compared to amount of hours required. The loss in productivity is a real measurement that must be weighed against how much people value kits and other dusted out cosmetic items. It’s up to each individual player to decide what they find valuable enough to invest their time in. No spreadsheet will ever completly solve that for you.

The last variable between theoretical profit and money in the bank? It is prep cost. Scouting supplies, food, and potions are up-front expenses which reduces the value of what you find on the table. Forgetting about those costs would of made everything appear more luxurius than it actualy is. Outside costs and supply drain fields let you input those expenses so you can view the true net impact once all bills are paid.

That helps prevent one of the most common mistakes: congratulating yourself on a high raw loot number while forgetting about the price tag you’re paying to earn it.

Nothing more than manage expectations, understand how groups work, and make decisions about which path to take, difficulty, time, and group makeup is not mutually exclusive. You input some stuff. You get some numbers. You change your plan accordingly. And then you return to the Chambers with a calmer mind.

Sometimes the loot window will still shock you. But now you’ll have some idea if you had a good night or simply made some loud noise.
