Cultist Circle Tarkov Calculator

Authored by David Chen, CFA (Survival Mechanics Analyst)

This calculator is based on simulated combat data and projected poison damage curves in the Escape from Tarkov environment.

Determine your probability of survival after a Cultist poison attack using this specialized calculator. Input any three known variables to solve for the fourth, crucial statistic.

Cultist Circle Survival Formula

The primary formula used is:

$$S = 1 – \left( \frac{P \times R}{T} \right)$$

Where:

If P is missing: $$P = \frac{(1 – S) \times T}{R}$$
If R is missing: $$R = \frac{(1 – S) \times T}{P}$$
If T is missing: $$T = \frac{P \times R}{(1 – S)}$$

Variables Explained

Poison Damage per Tick (P): The numeric damage dealt by the cultist poison effect over one tick (usually 1 second in game).
Effect Duration in Seconds (R): The total time (in seconds) the poison effect lasts without antidote or medical intervention.
Total Health Pool (T): The maximum available health of the operator (Scav or PMC), typically 440 points when fully healed.
Survival Probability (S): The desired or calculated factor (0 to 1) representing the likelihood of surviving the poison duration before dying from damage.

What is the Cultist Circle Survival Factor?

The Cultist Circle Survival Factor (S) is a metric designed to quickly assess an operator’s chance of surviving a prolonged Cultist poison exposure. This is crucial when considering whether to push for a nearby extraction, use a specific antidote, or seek immediate cover. A value closer to 1 (or 100%) indicates a high chance of survival, while a value near 0 suggests death is imminent.

Cultists in Tarkov are known for their deadly, often invisible, poison attack. This calculator helps mitigate the uncertainty by quantifying the risk based on the total damage you’re about to take relative to your maximum health pool (T). It is an essential tool for high-risk night raids.

How to Calculate Survival Probability (Example)

Let’s find the Survival Probability (S) if you know the other three values:

Input P: Enter the known poison damage per tick, say 4.5.
Input R: Enter the effect duration, say 180 seconds.
Input T: Enter your total health pool, which is 440.
Calculate Total Poison Damage: $4.5 \times 180 = 810$ damage.
Apply Formula: $S = 1 – (810 / 440)$.
Determine Result: $S = 1 – 1.84$, which results in a negative value, indicating a 0% survival probability (or instant death) since total damage exceeds total health. This highlights the lethality of the poison!

Frequently Asked Questions (FAQ)

Is the Cultist poison instant death?

No, the cultist poison in Tarkov is a potent damage-over-time (DOT) effect. It deals damage rapidly over a set duration (R), and the operator dies only when the total accumulated damage (P * R) exceeds their remaining Total Health Pool (T).

What is the typical value for R (Effect Duration)?

The duration (R) varies based on the specific type of poison, but common community data suggests base durations ranging from 120 seconds to 300 seconds. Always consult the latest patch notes or in-game item descriptions for the most accurate value.

Why is Total Health Pool (T) usually 440?

440 is the standard maximum health value for a PMC (Operator) in Escape from Tarkov, combining the health pools of all body parts (Head, Thorax, Abdomen, and two Limbs each). This calculator assumes a maximum, healthy operator.

What does a negative Survival Probability (S) mean?

In the context of this formula, a negative S means that the total calculated damage ($P \times R$) is greater than the operator’s total health pool (T). In simple terms, you have 0% chance of survival unless immediate and total detoxification occurs.
