What is the RS3 Prayer Calculator?
The prayer calculator rs3 is an essential tool for any RuneScape 3 player looking to efficiently train their Prayer skill. Prayer is one of the most vital combat skills in the game, providing powerful overhead protection prayers and game-changing stat-boosting curses like Soul Split. However, training Prayer is notoriously expensive, often costing hundreds of millions or even billions of Gold Pieces (GP) to reach high levels like 99 or 120.
This calculator removes the guesswork from planning your training. By inputting your current and target levels, the type of bone or ash you’re using, and your training method, it instantly calculates the exact number of items required and the total cost. This allows players to budget effectively, compare the cost-efficiency of different methods, and plan their path to unlocking powerful prayers and curses. Whether you’re aiming for 95 Prayer for Turmoil and Soul Split or going for the max cape at 99, a good prayer calculator is indispensable.
RS3 Prayer Formula and Explanation
The core calculation for determining the number of items needed is straightforward. It revolves around finding the total experience points (XP) required and dividing that by the amount of XP gained from each item used.
The basic formula is:
Items Needed = CEILING( (XP for Target Level - Current XP) / (Base XP per Item * Method Multiplier) )
The `CEILING` function is used to round up, ensuring you always account for enough items to reach your target, as you cannot use a fraction of a bone. The Method Multiplier is the crucial part that differentiates training methods, such as using a Gilded Altar, which provides a 350% XP boost (3.5x multiplier).
Variables Table
| Variable | Meaning | Unit / Type | Typical Range |
|---|---|---|---|
| Current XP | The player’s starting experience points. | Number (XP) | 0 – 200,000,000 |
| XP for Target Level | The total experience required to reach the target level. | Number (XP) | 83 – 104,273,167 |
| Base XP per Item | The base experience gained from a single bone or ash. | Number (XP) | 4.5 (Bones) – 200 (Searing Ashes) |
| Method Multiplier | The bonus XP factor from the chosen training method. | Multiplier (e.g., 1.0, 3.5) | 1.0 (Burying) – 4.0 (Ectofuntus) |
Practical Examples
Example 1: Getting to Soul Split (Level 92)
A player wants to unlock the powerful Soul Split curse, which requires level 92 Prayer. They are starting at level 70 and plan to use Dragon bones on a friend’s Gilded Altar.
- Inputs: Current Level: 70, Target Level: 92, Item: Dragon bones, Method: Gilded Altar.
- Calculation:
- XP for Level 92 is 6,517,253. XP for Level 70 is 879,557.
- Total XP Needed: 6,517,253 – 879,557 = 5,637,696 XP.
- XP per Dragon bone on Gilded Altar: 72 (base) * 3.5 (multiplier) = 252 XP.
- Result: Items Needed: CEILING(5,637,696 / 252) = 22,372 Dragon bones.
Example 2: A Budget Run to 99 Prayer
A different player wants to reach level 99 from 85 on a budget. They have discovered that using Powder of Burials with Infernal ashes is a cost-effective method.
- Inputs: Current Level: 85, Target Level: 99, Item: Infernal ashes, Method: Powder of Burials.
- Calculation:
- XP for Level 99 is 13,034,431. XP for Level 85 is 3,259,503.
- Total XP Needed: 13,034,431 – 3,259,503 = 9,774,928 XP.
- XP per Infernal ash with Powder of Burials: 62.5 (base) * 3.5 (multiplier) = 218.75 XP.
- Result: Items Needed: CEILING(9,774,928 / 218.75) = 44,685 Infernal ashes.

How to Use This Prayer Calculator RS3
- Enter Your Levels: Input your current Prayer level and your desired target level in the first two fields. For higher precision, you can input your exact current XP, which will override the level input.
- Select Your Item: From the dropdown menu, choose the bone or ash you will be using. The calculator includes a wide variety from low-level bones to high-level ashes.
- Choose Your Method: Select your training method from the second dropdown. This is critical, as the XP multiplier for a Gilded Altar (3.5x) is significantly different from simple burying (1.0x).
- Input Item Cost: Enter the current market price for a single unit of your chosen item. This allows the calculator to provide an accurate total cost estimate.
- Analyze the Results: The calculator will instantly display the total number of items needed (primary result), along with the total XP required, the total cost in GP, and the final XP you’ll get per item.
- Visualize and Reset: Use the chart to see your progress. If you want to start over with a new calculation, simply hit the “Reset” button.
Considering the high costs, a player might want to consult a runescape 3 money making guide to fund their training.
Key Factors That Affect Prayer Training
- Training Method: This is the single biggest factor. Using a Gilded Altar or Chaos Altar provides a 3.5x XP bonus, massively reducing the number of bones needed compared to just burying them.
- Bonus XP Weekend (DXPW): Importantly, Gilded Altars and the Ectofuntus do NOT benefit from Double XP Live events. However, methods like burying bones with Powder of Burials or using Cleansing Crystals do stack with bonus XP, making them extremely fast during these events.
- Prayer Brawling Gloves: These gloves, often obtained from the Wilderness, provide a massive XP boost (up to 4x) when training in the Wilderness, making the Chaos Altar an incredibly fast option.
- First Age Outfit: This skilling outfit provides up to a 6% prayer XP boost when all pieces are worn, slightly reducing the total items needed over a long grind.
- Powder of Burials: This item, when consumed, gives a 3.5x XP multiplier to burying bones anywhere for 30 minutes. It effectively turns burying into a Gilded Altar equivalent without needing to be in a Player-Owned House.
- GP/XP (Gold per Experience Point): The most important metric for budget-conscious players. Cheaper bones might seem better, but if they give very little XP, the GP/XP might be higher than more expensive, higher-XP bones. It’s often a balance between cost and speed. Our GP per XP calculator can help you with this.
Frequently Asked Questions (FAQ)
A: The “cheapest” way often involves slower methods or gathering your own supplies. Killing Vyrewatch with a Sunspear is a popular method that provides prayer XP over time without direct cost. For buying supplies, you must use a prayer calculator like this one to compare the GP/XP of items like Infernal Ashes vs. Dragon Bones at their current market prices.
A: Both offer the same 3.5x XP multiplier. The Chaos Altar in the Wilderness is slightly faster as banking is quicker, but it comes with the risk of being attacked by other players. The Gilded Altar in a Player-Owned House is completely safe but slightly slower. For a detailed comparison, see our rs3 herblore calculator, another skill with high costs.
A: This calculator shows the base calculation. If you are using bonus XP, you can simply halve the ‘Items Needed’ and ‘Total Cost’ results for a close approximation, assuming your method is compatible with DXPW.
A: Common goals are Level 70 for Piety prayers, Level 92 for Soul Split, Level 95 for Turmoil-type curses, and Level 99 for the max cape. A rs3 combat calculator can show how these prayers impact your performance.
A: Yes, but it is much slower. F2P is limited to burying bones like big bones and scattering ashes, without access to high-XP items or multipliers like the Gilded Altar.
A: Cleansing Crystals are an alternative training method in Prifddinas. They are stackable with bonus XP and can offer very high XP rates, especially during DXPW, but require a high initial cost and the Plague’s End quest completion.
A: No. The Dragon Rider Amulet’s effect of doubling XP from dragon bones only applies to burying them. It does not stack with the Gilded Altar or Powder of Burials multipliers.
A: The accuracy depends entirely on the ‘Cost per Item’ you provide. For the most accurate estimate, check the item’s current price on the Grand Exchange in-game before using the calculator.
