What is an Arknights Calculator?
An Arknights calculator is a specialized tool designed to help players of the popular tower defense game, Arknights, manage their in-game currency, specifically Orundum. The primary purpose of this calculator is to forecast how much Orundum a player can accumulate over a specific period. This allows for strategic planning for “headhunting,” which is the game’s gacha system for acquiring new operators. By inputting current resources and predictable future earnings, any player can use this Arknights calculator to determine how many pulls they can afford for an upcoming banner.
This tool is invaluable for both free-to-play players and those who spend money, as it provides a clear picture of saving potential. Instead of guessing, you can make informed decisions about which banners to pull on and which to skip, ensuring you have enough resources for high-priority operators. For any serious player, using an Arknights calculator is a key part of long-term account management and strategy.
The Arknights Calculator Formula and Mathematical Explanation
The calculation logic behind this Arknights calculator aggregates all standard, predictable sources of Orundum. It combines your existing resources with the income you’ll gain over a set number of days.
Step-by-Step Calculation:
- Base Orundum Calculation: The calculator starts with your current Orundum and adds the Orundum equivalent of your Originite Prime (1 Prime = 180 Orundum).
- Daily & Weekly Mission Income: Arknights provides 100 Orundum from daily missions and 500 from weekly missions. The calculator computes this as `(Days * 100) + (floor(Days / 7) * 500)`.
- Annihilation Income: A fixed weekly amount from Annihilation stages is added. This is calculated as `(floor(Days / 7) * WeeklyAnnihilationOrundum)`.
- Monthly Card Income: If active, the Monthly Card provides a flat 200 Orundum per day. This is simply `Days * 200`.
- Total Orundum and Pulls: All sources are summed to get the Total Orundum. This final number is then divided by 600, the cost of a single headhunting pull, to determine the Total Pulls.
This systematic approach makes the Arknights calculator an accurate and reliable planning tool.
Variables Table
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| Current Orundum | The Orundum you currently possess. | Orundum | 0 – 300,000+ |
| Current Originite Prime | The premium currency you have. | Originite Prime | 0 – 1,000+ |
| Days to Save | The period you are calculating for. | Days | 1 – 365 |
| Annihilation Orundum | Weekly reward from Annihilation stages. | Orundum/Week | 0 – 1800 |
Practical Examples of Using the Arknights Calculator
Example 1: Free-to-Play Player Saving for a Limited Banner
- Inputs: Current Orundum: 12,000; Originite Prime: 50; Days to Save: 90; Monthly Card: No; Annihilation Orundum: 1800/week.
- Intermediate Values:
- From Prime: 50 * 180 = 9,000 Orundum
- From Missions: (90 * 100) + (floor(90/7) * 500) = 9,000 + (12 * 500) = 15,000 Orundum
- From Annihilation: floor(90/7) * 1800 = 12 * 1800 = 21,600 Orundum
- Total Orundum: 12,000 + 9,000 + 15,000 + 21,600 = 57,600 Orundum
- Primary Result: 57,600 / 600 = 96 Pulls
- Interpretation: The player knows they can secure around 96 pulls in three months, which helps them decide if they have a good chance at hitting pity for the desired operator. This is a common use case for an Arknights calculator.
Example 2: Monthly Card User Planning for a Quick Save
- Inputs: Current Orundum: 2,000; Originite Prime: 5; Days to Save: 21; Monthly Card: Yes; Annihilation Orundum: 1700/week.
- Intermediate Values:
- From Prime: 5 * 180 = 900 Orundum
- From Missions: (21 * 100) + (floor(21/7) * 500) = 2,100 + (3 * 500) = 3,600 Orundum
- From Annihilation: floor(21/7) * 1700 = 3 * 1700 = 5,100 Orundum
- From Monthly Card: 21 * 200 = 4,200 Orundum
- Total Orundum: 2,000 + 900 + 3,600 + 5,100 + 4,200 = 15,800 Orundum
- Primary Result: floor(15,800 / 600) = 26 Pulls
- Interpretation: In just three weeks, the player can save enough for over two 10-pulls, a quick boost largely thanks to the monthly card. Any Arknights calculator should highlight the significant impact of the card.
How to Use This Arknights Calculator
Using this Arknights calculator is a straightforward process designed for clarity and ease of use.
- Enter Your Current Resources: Start by inputting your current Orundum and Originite Prime in the designated fields.
- Set Your Savings Goal: Enter the number of days you plan to save. This could be until the start of a new banner or just a general savings period.
- Specify Your Income Sources: Select whether you have an active Monthly Card and confirm your weekly Orundum income from Annihilation stages. 1800 is the current maximum for most veteran players.
- Review the Results: The calculator will instantly update. The primary result shows the total number of headhunting pulls you’ll have, while the intermediate values break down your total Orundum by source.
- Analyze the Chart and Table: Use the dynamic chart to see which income sources contribute the most. The projection table shows your week-by-week growth, helping you track milestones. Making a habit of using an Arknights calculator like this one can greatly improve your resource management.
Key Factors That Affect Arknights Calculator Results
- Events: This Arknights calculator only includes predictable, recurring income. It does not account for Orundum from new events, maintenance compensation, or one-time rewards, which can significantly boost your savings.
- Originite Prime Conversion: Deciding whether to convert Originite Prime into Orundum or save it for skins/level-up packs is a major decision. Converting it provides more pulls but sacrifices other potential value.
- Monthly Card Subscription: As the examples show, the Monthly Card is the single most efficient source of extra Orundum, nearly doubling daily income.
- Annihilation Progress: Players who haven’t unlocked or can’t consistently clear all Annihilation stages will have a lower weekly income, reducing their saving potential.
- Unplanned Spending: Using Orundum on anything other than pulls (e.g., Sanity refills) will obviously reduce your final pull count. A disciplined approach is necessary to meet goals set with an Arknights calculator.
- Headhunting Tickets: The calculation does not include Headhunting Permits from the credit store, green/gold certificate shops, or event rewards. These should be considered a bonus on top of the calculated pulls.
Frequently Asked Questions (FAQ)
The calculator is highly accurate for the defined recurring income sources (dailies, weeklies, annihilation, monthly card). Your actual pull count will likely be higher due to extra Orundum from events and login bonuses.
No, it focuses purely on Orundum-based income. Headhunting Permits from the Commendations and Distinctions store should be added to your final count manually.
This is the standard conversion rate within the in-game store. It’s generally recommended to use Originite Prime for special packs or skins, but converting it is an option for pure pulling power.
Yes, that’s its primary purpose. If you know a banner is approximately 60 days away, you can input that value to see if you can save enough pulls to hit pity (300 pulls for a limited operator).
Simply enter the amount you reliably earn each week. The Arknights calculator is flexible and will adjust the projection based on your input.
For the best results, you could update it weekly to track your progress. However, a single calculation at the start of your saving period is usually sufficient for a long-term goal.
No, the calculator only projects your owned resources. You should mentally add the free 10-pull and daily free pulls provided during limited banners to the total.
Using an Arknights calculator provides data-driven clarity. It removes emotion and guesswork, allowing for more effective and less stressful long-term planning, especially for free-to-play users.
