How to Use RoK Calculator
The RoK Calculator is a multi-mode browser tool for Rise of Kingdoms players who want to plan resource spending, training queues, speedup usage, healing, and power growth without switching between spreadsheets.
- Select a mode - Choose from Training, Resources, Speedups, Healing, or Power at the top of the RoK Calculator.
- Enter your values - Fill in troop tier, troop count, speed bonuses, current resources, or power targets depending on the active mode.
- Read the result panel - The RoK Calculator instantly shows training time, resource cost, resource gaps, speedup coverage, or the number of troops you need to reach your power goal.
Switch between modes at any time without losing data entered in other modes. All results update in real time so you can adjust assumptions and plan multiple scenarios quickly.
Formula & Theory - RoK Calculator
The RoK Calculator uses the following core formulas:
Training Time = BaseTime(tier) × TroopCount ÷ (1 + SpeedBonus% + AllianceBonus%)
Resource Cost = UnitCost(tier) × TroopCount
Healing Cost = TrainingCost × 0.30
Power Gain = PowerPerTroop(tier) × TroopCount
Troops Needed = ⌈(TargetPower − CurrentPower) ÷ PowerPerTroop(tier)⌉| Symbol | Meaning |
|---|---|
| BaseTime(tier) | Base training time in seconds per troop for the selected tier |
| UnitCost(tier) | Food / Wood / Stone / Gold cost per troop for the selected tier |
| SpeedBonus% | Your total training speed percentage from research, commanders, and equipment |
| AllianceBonus% | Additional speed percentage from alliance technology or help |
| PowerPerTroop(tier) | Power points awarded per trained troop for the selected tier |
Troop Tier Reference
The RoK Calculator uses the following community-standard base values:
| Tier | Base Time / troop | Power / troop | Food | Wood | Stone | Gold |
|---|---|---|---|---|---|---|
| T1 | 3 s | 6 | 80 | 60 | 0 | 0 |
| T2 | 12 s | 18 | 500 | 400 | 200 | 0 |
| T3 | 60 s | 54 | 3,500 | 2,800 | 1,400 | 700 |
| T4 | 300 s | 162 | 25,000 | 20,000 | 10,000 | 5,000 |
| T5 | 900 s | 486 | 150,000 | 120,000 | 60,000 | 30,000 |
Assumptions and Limits
Values are approximate community averages and may differ slightly across servers, civilization bonuses, or special events. Use the RoK Calculator for planning and cross-check with your in-game research panel for the most precise numbers.
Use Cases for RoK Calculator
The RoK Calculator is useful for Rise of Kingdoms players across all stages of the game. Common scenarios include:
- Pre-KvK training planning - Estimate how many T4 or T5 troops you can train before the next Kingdom vs. Kingdom event and whether your resources are enough.
- Speedup management - Use the speedup mode to check if your current stock of 1-minute, 60-minute, and 24-hour speedups can complete a large training queue before a time-limited event.
- Resource gap analysis - Enter your current Food, Wood, Stone, and Gold alongside your targets to immediately see which resources are short and by how much.
- Healing cost planning - Before attacking or being attacked in a rally, estimate the healing cost for your wounded troops so you are not caught off-guard.
- Power milestone planning - Set a power target and let the RoK Calculator tell you exactly how many troops of your preferred tier you need to train and what resources that will require.
