What is a RuneScape Prayer Calculator?
A RuneScape Prayer Calculator is an essential online tool designed for players of Old School RuneScape (OSRS) to efficiently plan their Prayer skill training. It helps determine the exact amount of experience points (XP) needed, the number of bones or ashes required, and the estimated Grand Exchange (GE) cost to reach a desired Prayer level. This calculator takes into account various factors such as your current Prayer level, target level, the type of bones or ashes you plan to use, and the specific training method (e.g., Gilded Altar, Chaos Altar, Ectofuntus) to provide accurate projections.
Who Should Use the RuneScape Prayer Calculator?
- Efficiency Scapers: Players who want to optimize their training for the fastest XP rates or the lowest cost per XP.
- Budget-Conscious Players: Those looking to achieve a specific Prayer level without overspending their hard-earned GP.
- Quest Cape/Achievement Diary Seekers: Many quests and achievement diaries require certain Prayer levels, and this tool helps plan for those requirements.
- PvMers and PKers: High Prayer levels are crucial for combat, enabling access to powerful overhead prayers and protection prayers.
- New and Returning Players: To understand the scale of the Prayer skill and plan their progression effectively.
Common Misconceptions About Prayer Training
Many players hold misconceptions about Prayer training, often leading to inefficient methods or unexpected costs. A common one is that “burying bones is always bad XP.” While direct burying is indeed slow, it’s often the only option for Ironmen early on, and the RuneScape Prayer Calculator helps quantify just how much slower it is compared to altars. Another misconception is that the Chaos Altar is “free XP.” While it saves bones due to its unique mechanic, it still requires initial bones and carries significant risk in the Wilderness. This RuneScape Prayer Calculator clarifies the actual XP rates and costs associated with each method, dispelling such myths.
RuneScape Prayer Calculator Formula and Mathematical Explanation
The RuneScape Prayer Calculator uses a series of straightforward calculations to provide its results. Understanding these formulas can help you make more informed decisions about your Prayer training strategy.
Step-by-Step Derivation:
- Determine Total XP Needed: The calculator first finds the cumulative XP required for your target level and subtracts the cumulative XP you already have at your current level.
- Calculate Base XP per Bone: Each bone or ash type has a fixed base XP value.
- Apply Altar Multiplier: Different altars and training methods provide varying XP bonuses. For example, a Gilded Altar with two lit burners offers 3.5 times the base XP.
- Incorporate Prayer Bonus: Items like the Holy Wrench or a full Prayer outfit provide a small percentage bonus to XP gained. This is added to the effective XP.
- Calculate Effective XP per Bone: This is the base XP multiplied by the altar multiplier and then further increased by any prayer bonus.
- Determine Total Bones Needed: The total XP required is divided by the effective XP gained per bone to find out how many bones you need.
- Estimate Total Cost: The total number of bones needed is multiplied by the Grand Exchange price of each bone to give an estimated total cost in GP.
- Calculate Cost per XP: The total cost is divided by the total XP needed to show the efficiency of your chosen method in terms of GP spent per experience point.

Practical Examples Using the RuneScape Prayer Calculator
Let’s look at a couple of real-world scenarios to demonstrate how the RuneScape Prayer Calculator can be used to plan your Prayer training.
Example 1: Reaching Level 70 Prayer for Piety
A player wants to unlock the Piety prayer, which requires level 70 Prayer. They are currently level 50 and have decided to use Dragon Bones at a Gilded Altar with two lit burners, also utilizing their Holy Wrench and full Prayer outfit for the XP bonus. Dragon Bones are currently 2,000 GP each.
- Current Prayer Level: 50
- Target Prayer Level: 70
- Bone/Ash Type: Dragon Bones (72 base XP)
- Altar/Method: Gilded Altar (3.5x multiplier)
- Cost per Bone: 2,000 GP
- Prayer XP Bonus: Yes (3.5%)
RuneScape Prayer Calculator Output:
- Total XP Needed: 324,806 XP (411,715 XP for Lvl 70 – 86,909 XP for Lvl 50)
- Effective XP per Bone: 72 * 3.5 * (1 + 0.035) = 252 * 1.035 = 260.82 XP
- Total Bones Needed: 324,806 / 260.82 ≈ 1,245 bones
- Estimated Total Cost: 1,245 * 2,000 GP = 2,490,000 GP
- Cost per XP: 2,490,000 GP / 324,806 XP ≈ 7.66 GP/XP
Interpretation: This player will need approximately 1,245 Dragon Bones and around 2.5 million GP to reach level 70 Prayer, making it a relatively quick and affordable goal with this method.
Example 2: Achieving Level 99 Prayer with Infernal Ashes
An experienced player aims for the prestigious level 99 Prayer cape. They are currently level 90 and plan to use Infernal Ashes at the Chaos Altar for its efficiency, accepting the Wilderness risk. Infernal Ashes are currently 6,000 GP each. They will also use their Prayer XP bonus gear.
- Current Prayer Level: 90
- Target Prayer Level: 99
- Bone/Ash Type: Infernal Ashes (62.5 base XP)
- Altar/Method: Chaos Altar (3.5x multiplier)
- Cost per Bone: 6,000 GP
- Prayer XP Bonus: Yes (3.5%)
RuneScape Prayer Calculator Output:
- Total XP Needed: 12,158,707 XP (13,034,431 XP for Lvl 99 – 875,724 XP for Lvl 90)
- Effective XP per Ash: 62.5 * 3.5 * (1 + 0.035) = 218.75 * 1.035 = 226.40625 XP
- Total Ashes Needed: 12,158,707 / 226.40625 ≈ 53,703 ashes
- Estimated Total Cost: 53,703 * 6,000 GP = 322,218,000 GP
- Cost per XP: 322,218,000 GP / 12,158,707 XP ≈ 26.50 GP/XP
Interpretation: Reaching level 99 Prayer from level 90 using Infernal Ashes at the Chaos Altar will require over 53,000 ashes and cost approximately 322 million GP. This highlights the significant investment required for maxing out a skill like Prayer, even with efficient methods. The RuneScape Prayer Calculator helps set realistic expectations.

Key Factors That Affect RuneScape Prayer Calculator Results
The accuracy and utility of the RuneScape Prayer Calculator depend on several key factors. Understanding these can help you manipulate the inputs to find the most optimal training strategy for your specific goals.
- Current and Target Prayer Levels: These are fundamental. The higher the target level from your current, the more XP, bones, and GP will be required. The XP curve in RuneScape is exponential, meaning higher levels require significantly more XP.
- Bone/Ash Type: Different bones and ashes offer varying base XP values. For instance, Dragon Bones give 72 XP, while Infernal Ashes give 62.5 XP. Choosing a higher base XP item generally reduces the number of items needed but often comes with a higher individual item cost.
- Altar/Training Method: This is perhaps the most impactful factor.
- Gilded Altar (POH): Provides a 3.5x XP multiplier with two lit burners, making it a popular choice for high XP rates in a safe environment.
- Chaos Altar (Wilderness): Also offers a 3.5x XP multiplier and has a 50% chance to not consume bones, effectively doubling the bones’ value. However, it’s in the Wilderness, carrying PvP risk. The RuneScape Prayer Calculator assumes bones are consumed for the base calculation, but players should factor in the bone-saving effect for actual cost.
- Ectofuntus: Offers a 4x XP multiplier, the highest in the game, but requires a lengthy process of grinding bones into bonemeal and collecting ecto-tokens, making it slower per hour but highly XP-efficient per bone.
- Burying Bones: Provides only 1x XP, making it the slowest and least efficient method, typically only used for very low levels or by Ironmen without other options.
- Cost per Bone/Ash (Grand Exchange Price): The fluctuating market price of bones and ashes directly impacts the total GP cost. Monitoring GE prices and buying during dips can save millions. This is a critical input for the RuneScape Prayer Calculator to provide accurate cost estimates.
- Prayer XP Bonuses: Small percentage bonuses from items like the Holy Wrench (+2% XP) and a full Prayer outfit (+2.5% XP) can add up over millions of XP, slightly reducing the total bones and cost. While individually small, they are “free” XP boosts once acquired.
- Efficiency vs. Risk vs. Effort: Players must balance these. High XP methods like Gilded Altar are safe but require constant banking. Chaos Altar is risky but can be very cost-effective. Ectofuntus is high XP per bone but very click-intensive and slow per hour. The RuneScape Prayer Calculator helps quantify the raw numbers, allowing you to weigh these qualitative factors.
Frequently Asked Questions (FAQ) about the RuneScape Prayer Calculator
A: The fastest way to train Prayer is typically by offering Dragon Bones or Superior Dragon Bones at a Gilded Altar in a Player-Owned House (POH) with two lit burners, or at the Chaos Altar in the Wilderness. Both offer 3.5x base XP. The RuneScape Prayer Calculator can help you compare the exact XP rates and costs.
A: The Chaos Altar has a 50% chance to not consume bones, effectively halving the number of bones needed for the same XP compared to a Gilded Altar (assuming no bone loss to PKers). This makes it significantly cheaper per XP, but it comes with the risk of being attacked by other players in the Wilderness. The RuneScape Prayer Calculator can show you the raw cost difference.
A: The cost for 99 Prayer varies greatly depending on your starting level, chosen bone type, and training method. It can range from tens of millions to hundreds of millions of GP. For example, using Dragon Bones at a Gilded Altar from level 1 could cost over 100 million GP. Use the RuneScape Prayer Calculator to get a precise estimate based on current GE prices and your specific plan.
A: The Ectofuntus is a training method that offers the highest XP per bone (4x base XP). It involves collecting ecto-tokens, grinding bones into bonemeal, and then offering the bonemeal at the Ectofuntus. While highly XP-efficient per bone, it is very click-intensive and generally slower per hour than Gilded Altars due to the preparation steps. The RuneScape Prayer Calculator includes this option.
A: No, there are no Prayer level requirements to offer or bury any type of bones or ashes. However, higher-level bones typically give more XP and are more expensive.
A: Key items that provide a Prayer XP bonus include the Holy Wrench (+2% XP), and the full Prayer outfit (vestments, stole, mitre, crozier, boots) which provides an additional +2.5% XP. These bonuses are cumulative. Our RuneScape Prayer Calculator accounts for these bonuses.
A: Yes, Ironmen can use this RuneScape Prayer Calculator to plan their Prayer training. However, they must consider that they cannot buy bones from the Grand Exchange. They will need to factor in the time and effort required to obtain bones through combat or other in-game activities, and the “cost” will be in terms of time and resources spent, rather than GP.
A: Differences can arise from several factors: slight variations in XP tables used, different assumptions for altar multipliers (e.g., some calculators might assume 2.5x for Gilded Altar without burners, while ours assumes 3.5x with two burners), or different default values for XP bonuses. Always ensure the inputs match across calculators for a fair comparison. Our RuneScape Prayer Calculator strives for accuracy based on common OSRS practices.
