What is an SMTV Fusion Calculator?
An smtv fusion calculator is an essential tool for players of Shin Megami Tensei V (and the Vengeance edition) to navigate the complex system of demon creation. In SMTV, demons are not just captured; they are fused together to create more powerful entities with customized skill sets. Understanding the underlying math behind the smtv fusion calculator allows players to plan their team progression, ensure they have the right resistances for boss fights, and optimize their Macca spending in the World of Shadows.
Whether you are a newcomer or a veteran of the series, a smtv fusion calculator helps demystify why certain combinations result in specific demons. It calculates the “Target Level” by averaging the base levels of two demons and adding a fixed increment, then cross-references this with the smtv demon fusion chart to determine the final race and species.
SMTV Fusion Calculator Formula and Mathematical Explanation
The core logic of a smtv fusion calculator follows a strict mathematical derivation. Unlike other RPGs where fusion might be random, SMTV uses a deterministic formula based on “Base Levels” rather than “Current Levels.”
The Step-by-Step Derivation
1. Average Level Calculation: Take the base level of Demon A and Demon B.
2. The Offset: Add 1 to the average.
3. Race Determination: Use the internal race priority matrix.
4. Demon Selection: The result is the demon within the resulting race whose base level is the lowest possible level that is equal to or higher than the calculated Target Level.
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| L1 | Base Level of Demon 1 | Level | 1 – 99 |
| L2 | Base Level of Demon 2 | Level | 1 – 99 |
| Result Level | Min. Threshold for Result | Level | 2 – 99 |
| Race Factor | Internal Race ID | Category | ~40 Races |
Practical Examples (Real-World Use Cases)
Example 1: Creating a Mid-Game Beast
Suppose you are using the smtv fusion calculator to fuse a Divine Angel (Base Level 10) and a Snake Naga (Base Level 25).
Inputting these into the smtv fusion simulator: (10 + 25) / 2 = 17.5. Adding the +1 offset gives us 18.5. The result will be the lowest level Beast demon with a base level of 19 or higher, likely leading to a Makami or Inugami depending on specific version data.
Example 2: End-Game Optimization
If you have a high-level Herald and a Megami, the smtv fusion calculator predicts an Avian result. If the calculated target level is 78, the game checks the Avian race for the demon closest to level 78 without going under. This is critical for planning smtv special fusions that require specific high-level ingredients.
How to Use This SMTV Fusion Calculator
- Enter Base Levels: Find the “Base Level” in the demon compendium. Do not use the level increased by experience points, as the smtv demon level calculator only looks at the starting stats.
- Select Races: Choose the races of both ingredients. This determines the output category.
- Analyze the Target Level: Look at the highlighted result. This is the minimum level the resulting demon must have.
- Check the Chart: Use the visual scaling chart to see how much “Leveling up” your fusion provides.
- Consult the Resulting Race: Our smtv fusion calculator automatically predicts the resulting race based on standard SMTV logic.

Key Factors That Affect SMTV Fusion Results
- Base Level vs. Current Level: This is the #1 mistake. The smtv fusion calculator uses the level the demon starts with, not what it currently is after grinding.
- Race Combinations: Every race pairing has a set outcome. Fusing two demons of the same race often results in an “Element” demon.
- Special Fusion Restrictions: Some demons, like certain Fiends or Deities, cannot be made via normal fusion and won’t show up in a standard smtv fusion calculator result without special conditions.
- Player Level: You cannot fuse a demon that is a higher level than the Protagonist (Nahobino) unless you have unlocked specific Miracles.
- Miracles: Miracles like “Rank Fusion” can alter how levels or skills are inherited, impacting your smtv fusion simulator planning.
- DLC and Expansion Content: In SMTV Vengeance, new demons and races shift the smtv demon fusion chart, making updated calculators vital.
Frequently Asked Questions (FAQ)
Ensure you are using the Base Level. If your demon has leveled up through combat, it doesn’t change the fusion math in the smtv fusion calculator.
Reverse fusion allows you to pick a result demon and see which ingredients in your current party or compendium can create it, effectively acting as an inverse smtv fusion simulator.
No, those are smtv special fusions. They require specific recipes (e.g., 4 specific demons) rather than the standard two-demon formula.
Fusing two demons of the same race produces an Element. Fusing an Element with another demon will either rank that demon up or down within its own race.
Yes. Typically, the result demon’s base level cannot exceed your current level. The smtv demon level calculator tells you what the demon *would* be, but you might be blocked from creating it.
No, stats only affect the strength of the result, not which demon is created. Only Race and Base Level matter for the smtv fusion calculator.
The core math remains the same, but new demons have been added to the smtv demon fusion chart, which can change the specific demon result for certain level thresholds.
A rare occurrence where the smtv fusion calculator prediction is ignored, and a random (often rare) demon is produced instead. This usually happens during a Full Moon (Magatsuhi) state.
