Arknight Calculator

Operator Leveling Calculator

Calculate the EXP and LMD required to level up your Arknights operators.

What is the Arknights EXP Calculator?

The Arknights EXP Calculator is a tool designed for players of the mobile game Arknights to estimate the amount of experience points (EXP) and Lungmen Dollars (LMD) required to level up their operators from a current level and promotion stage to a desired target level and promotion stage. It helps players plan their resource farming and allocation efficiently.

Anyone playing Arknights who wants to optimize their operator progression should use this calculator. It’s particularly useful for planning how many Battle Records (EXP cards) and LMD you need to save or farm to reach specific operator milestones, like Elite 1 or Elite 2 promotions.

A common misconception is that the LMD cost shown includes promotion costs. This Arknights EXP Calculator primarily focuses on the LMD cost directly associated with using Battle Records for leveling (1 LMD per 10 EXP). Promotion costs (LMD and materials) are separate and significant, and should be considered additionally.

Arknights EXP Calculator Formula and Mathematical Explanation

The calculation is based on the cumulative EXP required to reach each level within each promotion stage (Elite 0, Elite 1, Elite 2). The game uses predefined EXP tables for each stage.

Let:

• `C_Promo`, `C_Lvl`, `C_Exp` be the current promotion, level, and EXP within that level.
• `T_Promo`, `T_Lvl` be the target promotion and level.
• `CumulExp_E0[lvl]`, `CumulExp_E1[lvl]`, `CumulExp_E2[lvl]` be the total EXP needed to reach level `lvl` from level 1 of Elite 0, Elite 1, and Elite 2 respectively (with `CumulExp_E0[0] = 0` for level 1).
• `MaxLvl_E0`, `MaxLvl_E1`, `MaxLvl_E2` be the max levels for each promotion stage (varying by rarity).

The total EXP needed is calculated by summing the EXP required to:

1. Go from `C_Lvl` + `C_Exp` to `MaxLvl_E0` if `C_Promo` is 0 and `T_Promo` > 0.
2. Go from E0 max to E1 max if needed and `T_Promo` is 2.
3. Go from the start of the target promotion to `T_Lvl`.

If `C_Promo == T_Promo`, Total EXP = `(CumulExp_E[T_Lvl-1] – (CumulExp_E[C_Lvl-1] + C_Exp))`.

If `C_Promo < T_Promo`, it sums EXP across stages. For example, E0 L20 to E1 L70: EXP(E0 L20 to E0 Max) + EXP(E1 L1 to E1 L70).

LMD cost for leveling = Total EXP / 10.

Variables used in the Arknights EXP Calculator

Variable	Meaning	Unit	Typical Range
Current Promotion	Operator’s current promotion stage	E0, E1, E2	0, 1, 2
Current Level	Operator’s level within current promotion	Level	1 – Max (e.g., 50 for E0 6*)
Current EXP	EXP towards next level	EXP	0 – (EXP for next level – 1)
Target Promotion	Desired promotion stage	E0, E1, E2	0, 1, 2
Target Level	Desired level within target promotion	Level	1 – Max (e.g., 90 for E2 6*)
Total EXP Needed	Total experience points required	EXP	0+
Total LMD Needed	LMD cost for leveling via EXP cards	LMD	0+

Practical Examples (Real-World Use Cases)

Example 1: Leveling a new 6-star operator to Elite 1 Max

• Current: E0, Level 1, 0 EXP
• Target: E1, Level 80 (Max for 6*)
• Rarity: 6 Star

The Arknights EXP Calculator would first calculate the EXP from E0 L1 to E0 L50, then add the EXP from E1 L1 to E1 L80. This would give a large total EXP, which translates to a specific number of Battle Records and a significant LMD cost for leveling, plus the separate E1 promotion costs.

Example 2: Taking an E1 operator to E2 Level 40

• Current: E1, Level 30, 500 EXP
• Target: E2, Level 40
• Rarity: 6 Star

The Arknights EXP Calculator calculates EXP from E1 L30 (with 500 EXP) to E1 L80, then adds EXP from E2 L1 to E2 L40. The total EXP and LMD are shown, highlighting the resources needed before and after the E2 promotion (which itself costs LMD and materials not covered by the leveling LMD).

How to Use This Arknights EXP Calculator

1. Select Operator Rarity: Choose the star rating of your operator to set correct max level defaults.
2. Enter Current State: Select the current promotion (E0, E1, E2), enter the current level, and the EXP already accumulated towards the next level.
3. Enter Target State: Select the desired promotion and enter the target level.
4. Check Max Levels: Ensure the levels entered are within the max for the selected rarity and promotion (helper text indicates max).
5. Calculate: The results update automatically, or click “Calculate”.
6. Read Results: The calculator shows Total EXP Needed, LMD for leveling, and a breakdown of Battle Record types. The chart visualizes EXP distribution.

Use the results to plan your farming. If you need 100,000 EXP, you know you need to farm roughly 50 of the 2000 EXP Battle Records (from CE-5/6) and 10,000 LMD from LS-5/6, plus more LMD for the promotion itself.

Key Factors That Affect Arknights EXP Calculator Results

• Operator Rarity: Different rarities have different max levels at E0 and E1 (and E2 for 4/5 stars), affecting total EXP to max them out. 6-stars require the most.
• Current vs. Target Level/Promotion: The larger the gap between current and target, the more EXP and LMD are needed. Jumps across promotions (E0 to E1, E1 to E2) require significant EXP.
• Current EXP into Level: Having some EXP already reduces the total needed slightly.
• Battle Record Farming Efficiency: The stages you farm for Battle Records (CE-1 to CE-6) give different amounts and types, affecting how quickly you acquire the needed EXP. Our Sanity Calculator can help plan farming.
• LMD Farming Efficiency: Similarly, LMD farming stages (LS-1 to LS-6) influence how fast you get the LMD for leveling and promotions.
• Promotion Costs: While not calculated here, the LMD, Chips, and materials for promotion are substantial and must be farmed alongside EXP and leveling LMD. See our Material Farming Guide.

Frequently Asked Questions (FAQ)

Q: Does this calculator include promotion costs?
A: No, this Arknights EXP Calculator only calculates the EXP and the LMD cost associated with using Battle Records (1 LMD per 10 EXP). Promotion costs (LMD, Chips, materials) are separate and need to be factored in manually.

Q: What are the max levels for each rarity and promotion?
A: For 6-star: E0-50, E1-80, E2-90. 5-star: E0-45, E1-70, E2-80. 4-star: E0-40, E1-60, E2-70. 3-star: E0-30, E1-55. 2-star: E0-30, E1-45. 1-star: E0-30. The calculator adjusts max levels based on selected rarity.

Q: How much LMD does it cost to use Battle Records?
A: It costs 1 LMD for every 10 EXP gained from Battle Records.

Q: Where do I farm Battle Records and LMD efficiently?
A: Battle Records are farmed from Cargo Escort (CE) stages, and LMD from Tactical Drill (LS) stages. The highest available stages (CE-6, LS-6) are generally the most Sanity-efficient.

Q: Why does the chart show different bars?
A: The chart breaks down the total EXP needed into components: EXP required within the current promotion, and EXP needed in subsequent promotions if you’re promoting the operator.

Q: Can I use this for operators below 6-star?
A: Yes, select the correct rarity, and the max levels for E0 and E1 will adjust, giving you an accurate Arknights EXP Calculator for any operator.

Q: What if I enter a level higher than the max for the selected promotion/rarity?
A: The input field will show an error, and the calculation might not be accurate. Always respect the max levels shown in the helper text after selecting rarity and promotion.

Q: How accurate is this Arknights EXP Calculator?
A: The EXP and leveling LMD calculations are very accurate, based on the game’s known EXP tables. Promotion costs are not included.
