A) What is the Arknights Calculator?
The Arknights Calculator is a strategic resource management tool designed for Doctors to track their "Sparking" progress. In Arknights, limited banners usually require 300 pulls to guarantee a specific 6-star operator. Our calculator aggregates your daily missions, weekly rewards, and monthly card benefits to give you a precise timeline for your savings.
Whether you are saving for the next "Texas the Omertosa" or "Mlynar" rerun, knowing your exact Orundum count is essential for resource optimization.
B) Formula and Explanation
The math behind the calculator follows the standard Rhodes Island economic cycle. The formula for total pulls is:
Total Pulls = [Current Orundum + (Daily Missions * Days) + (Weekly Missions * Weeks) + (Annihilation * Weeks) + (Monthly Card * Days)] / 600 + Current Tickets + (OP * 180 / 600)
- Daily Missions: 100 Orundum per day.
- Weekly Missions: 500 Orundum per week.
- Annihilation: Up to 1800 Orundum per week.
- Originium Prime (OP): 1 OP = 180 Orundum.
- Pull Cost: 1 Single Pull = 600 Orundum.
C) Practical Examples
| Scenario | Daily Gain | Weekly Gain | Pulls per Month |
|---|---|---|---|
| Free to Play (F2P) | 100 | 2300 | ~20.5 |
| Monthly Card Holder | 300 | 2300 | ~30.5 |
| Whale (Pack Buyer) | Varies | 2300+ | 50+ |
Example 1: A F2P player with 0 Orundum starting 60 days before a banner will accumulate roughly 41 pulls from missions and Annihilation alone.
Example 2: A Monthly Card player starting with 18,000 Orundum (30 pulls) and 60 days of lead time will reach approximately 91 pulls.
D) How to Use step-by-step
- Enter Current Assets: Look at your in-game dashboard and input your Orundum, OP, and Tickets.
- Set Timeline: Estimate how many days are left until the banner you want to pull on.
- Toggle Bonuses: Select if you have an active Monthly Card or if you complete your Annihilation runs.
- Review Results: The calculator updates in real-time. Check the "Total Equivalent Pulls" to see if you can reach the 300-pull spark limit.
E) Key Factors Affecting Your Savings
- Yellow Certificate Shop: You can buy up to 38 pulls per month using 258 Distinctions. This is not included in the base calc as it depends on your pulling frequency.
- Event Rewards: Most events give 10-15 OP and sometimes Headhunting permits.
- Maintenance Compensation: Typically 200 Orundum per update.
- Green Certificate Shop: Tier 1 rewards include a small amount of Orundum and tickets.

A: Exactly 600 Orundum.
Q5: How many pulls per month can a F2P get?
A: Roughly 20-24 pulls depending on event frequency.

A: Soft pity starts at the 51st pull, increasing the 6-star rate by 2% per pull.
Q8: Can I farm Orundum in stages?
