Plan your Warframe relic farming with transparent math. We model the official drop tables for all refinement tiers (Intact, Exceptional, Flawless, Radiant), and compute best-of-squad probabilities so four Tenno can coordinate refinements and pick the highest-value reward every run. You'll also find expected value (EV) per run, EV per relic, confidence for "at least one copy" after N runs, plus a practical checklist on when to stop refining or switch targets. Every tool is documented with assumptions, formulas, worked examples, edge cases, and common mistakes—so you can verify the numbers and adapt them to your group's budget and time constraints.
Compute per-run success with best-of-squad selection, rare/uncommon/common buckets, EV from rare-only and full-table EV. Includes Radiant/Flawless/ Exceptional/Intact tiers, custom prices, squad size, and confidence by runs.

Each refinement tier shifts the probability distribution across rare, uncommon, and common rewards. Radiant relics maximize your chance at rare drops, while Intact relics offer the most economical option for farming common and uncommon items. Our calculator models all four tiers with official drop rates, helping you decide when it's worth spending Void Traces to refine versus running more missions with unrefined relics.
The best-of-squad mechanic multiplies your odds significantly - when four players each open a relic, you get to choose from four reward pools, dramatically increasing the probability of seeing at least one rare drop in the group.
Radiant refinement is strongest when the rare reward is your only target or when the squad is coordinating the same relic. If all four players bring a Radiant copy, the run produces four independent reward pools and lets the squad pick the best visible outcome. That is different from running one Radiant relic solo: the per-relic rare chance is higher than Intact, but the trace cost may not be justified if the rare part has low market value or if you mainly need uncommon rewards.
The calculator separates three questions that are often mixed together: chance per relic, chance per mission, and expected value after trace cost. A rare-only target may favor Radiant radshare runs; a ducat farm may favor cheaper tiers with faster mission loops; and a player farming for a full set may switch tiers once the rare piece is complete. Keeping those goals separate prevents over-refining every relic out of habit.
Use a small log of real runs to calibrate time. Capture mission type, squad size, refinement tier, target reward, and whether the target appeared. Five to ten runs is not enough to prove a drop rate, but it is enough to estimate your route time and decide whether a faster fissure beats a slower mission with the same probability table.
For a fixed target chance p, the chance of seeing at least one copy after n independent relic outcomes is 1 - (1 - p)^n. In squad play, n is the number of visible reward pools, not merely the number of missions you personally start. Four coordinated players opening one relic each create four visible pools in a single mission.
EV uses the full reward table when prices are available. Rare-only planning is useful for one target, but it can understate the value of forma blueprints, uncommon prime parts, and ducat conversions. If market prices are stale, update the values inside the calculator before comparing tiers.
LootCalc treats Warframe relic math as a transparent planning model, not a promise about the next mission. Every output should be read as a long-run expectation with variance. For deeper definitions, use the Methodology andGlossary pages alongside the calculator.
Do not read a ninety percent confidence output as a guarantee. It means that, under the stated relic chance and squad setup, ninety out of one hundred similar farming plans would see at least one copy by that point. The remaining plans can still miss. That is why the calculator shows confidence bands and not a promise about the next fissure.
Also separate player choice from squad choice. In a radshare, every player sees the same four visible rewards and may pick the best item for their goal. In public groups, relic tiers and target items may not match, so the "best-of-squad" model can overstate your target odds unless the squad is actually coordinated.
Finally, trace cost is an opportunity cost. Spending traces on a low-value rare part can be worse than saving those traces for a different relic, even when the Radiant tier improves the immediate success chance. Use the editable values to test that trade-off before refining.
