What is a Phasmophobia Calculator?
A phasmophobia calculator is an essential tool for players of the ghost-hunting game, Phasmophobia. Its primary purpose is to simplify the core gameplay loop: identifying the ghost type haunting a location. Instead of manually flipping through the in-game journal, this calculator allows you to input the evidence you’ve found (like EMF Level 5 or Freezing Temperatures), and it instantly narrows down the list of potential ghosts. This process of elimination is the key to success in Phasmophobia, and using a calculator makes it faster, more accurate, and less prone to error during a tense investigation.
This tool is for anyone, from beginners struggling to remember the evidence for all 24 ghost types to veteran players on Nightmare difficulty who need to make quick deductions with limited information. A common misunderstanding is that this is a mathematical calculator; it’s actually a logic-based deduction tool that automates the cross-referencing process you would otherwise do by hand.
Phasmophobia Formula and Explanation
The “formula” behind this phasmophobia calculator is a logical filtering process. The game has 24 unique ghost types, and each one is tied to a specific combination of three types of evidence. There are seven evidence types in total. The calculator works by maintaining a complete database of all ghosts and their corresponding evidence.
When you select an evidence type you’ve found, the calculator filters its list to show only the ghosts that have that evidence. As you add more evidence, the list of possibilities shrinks. The goal is to find three pieces of evidence to pinpoint a single ghost type. The table below serves as the complete database for this logical deduction.

Practical Examples
Understanding how to use the calculator is best shown through examples. Here are a couple of common scenarios you might encounter during an investigation.
Example 1: A Standard Investigation
- Inputs: Your team has explored the house and found two definitive pieces of evidence: the ghost has responded through the Spirit Box, and you’ve seen Ghost Orbs through the video camera.
- Using the Calculator: You would check the “Spirit Box” and “Ghost Orb” boxes on the phasmophobia calculator.
- Results: The calculator would instantly update to show a narrowed list of possible ghosts: Mare, Onryo, Phantom, Yokai, and Yurei. The “Remaining Evidence” section would show that you should now be looking for D.O.T.S. Projector, Freezing Temperatures, or Ghost Writing to make your final identification.
Example 2: A Confusing Case
- Inputs: The ghost is very active. You’ve confirmed Fingerprints on a door and recorded EMF Level 5 spikes.
- Using the Calculator: Check the “Ultraviolet” and “EMF Level 5” boxes.
- Results: The calculator narrows the possibilities down to Goryo, Jinn, Myling, Obake, and Spirit. Knowing these possibilities, you can check our phasmophobia evidence chart to see what the third evidence could be (D.O.T.S., Freezing, or Ghost Writing) and focus your efforts.
How to Use This Phasmophobia Calculator
Using this tool is straightforward and designed to be done in the middle of a game, even with a ghost breathing down your neck. Follow these simple steps for effective ghost identification.
- Gather Evidence: Play the game and use your starter equipment (EMF Reader, Spirit Box, Video Camera, etc.) to find clues.
- Select Found Evidence: As soon as you confirm a piece of evidence, click the corresponding checkbox in the calculator above. The list of possible ghosts will update instantly.
- Review Possibilities: The “Possible Ghost Types” section will show you what remains. The “Ghost Possibilities” count tells you how many options you still have.
- Focus Your Search: Look at the “Possible Remaining Evidence” box. This tells you exactly what evidence types are still in play and what you should be looking for next. This is a crucial step in our ghost identification guide.
- Identify the Ghost: Once you have three pieces of evidence selected, the calculator should ideally show only one ghost type. Congratulations, you’ve found your ghost!
- Reset for Next Game: Click the “Reset” button to clear all selections and prepare for your next contract.
Key Factors That Affect Ghost Identification
While a phasmophobia calculator relies on the three core evidence types, your success is influenced by several other in-game factors.
- Difficulty Level: On Amateur and Intermediate, you get a setup time. On Professional and Nightmare, you don’t, increasing the pressure. Nightmare difficulty hides one piece of evidence, forcing you to rely on behavioral tells.
- Sanity: Your team’s average sanity is critical. Lower sanity can trigger more paranormal events and hunts, giving you more data but also increasing the danger. Managing it is key, as discussed in our phasmophobia sanity guide.
- Ghost-Specific Behaviors: Many ghosts have unique tells. A Raiju moves faster near active electronics, while an Onryo fears fire and may be prevented from hunting by a candle. Learning these behaviors is vital for no-evidence runs.
- Cursed Possessions: Items like the Ouija Board or Music Box can force interactions, helping you gather clues faster. However, they come at a high sanity cost and can trigger a cursed hunt. Our guide on cursed possessions explained is a must-read.
- The Mimic: This special ghost can copy the traits and behaviors of other ghosts. It will always show Ghost Orbs as a fourth, “fake” piece of evidence, a key giveaway to watch for.
- Team Communication: Clear communication is paramount. Calling out evidence as you find it allows the team member with the calculator to update the possibilities for everyone. Efficient teamwork is often the difference between success and failure.
Frequently Asked Questions (FAQ)
1. What if I can only find two pieces of evidence?
This is a common scenario, especially on higher difficulties. If you have two evidence types, the calculator will give you a short list of possibilities. You must then use your knowledge of ghost behaviors (e.g., speed, hunt patterns, abilities) to determine the correct type from the remaining options.
2. The calculator shows “The Mimic” as a possibility, what does that mean?
The Mimic is a special ghost that shows three standard evidence types plus a guaranteed, but fake, fourth evidence: Ghost Orbs. If you have three evidence types selected and The Mimic is still a possibility, check for Ghost Orbs. If orbs are present with your other three clues, you have found The Mimic.
3. How do I use the phasmophobia calculator on Nightmare difficulty?
On Nightmare, one piece of evidence is always hidden. Use the calculator to input the two pieces of evidence you find. This will give you a small list of potential ghosts. You must then differentiate them based on their unique strengths, weaknesses, and behaviors detailed in the game’s journal and our all ghost types phasmophobia guide.
4. What does the “Ruled Out” evidence feature do?
Some advanced calculators allow you to mark evidence as “ruled out” (e.g., you’ve confirmed temperatures are not freezing). This tool simplifies that by only requiring you to select what you *have* found, which is a faster and more reliable workflow during a hunt.
5. Is this calculator updated with the latest game changes?
Yes, this phasmophobia calculator is maintained to reflect the current version of the game, including all 24 ghost types and their correct evidence combinations. It includes new ghosts as they are released.
6. Can I use this tool for a no-evidence run?
This calculator is primarily designed for evidence-based identification. For a no-evidence run, you would rely entirely on behavioral tells. However, you can use the evidence table on this page as a reference sheet to keep track of which ghosts you’ve ruled out by observing their behavior.
7. How do I know if I have Freezing Temperatures without a thermometer?
If you don’t have a thermometer or it’s broken, you can identify Freezing Temperatures by seeing your own breath forming cold clouds in the air while you are in the ghost’s room. This is a definitive visual cue.
8. Why isn’t the Spirit Box working?
To get a response from a Spirit Box, the lights in the room must be off, and you must be asking a valid question close to the ghost. Some ghosts only respond to players who are alone. Check out our how to use spirit box guide for more details.
