XP vs. Log Type Cost

Comparison of XP gained versus the cost per log for various log types.

Firemaking in Old School RuneScape (OSRS) is a gathering and utility skill that allows players to burn logs, creating fires that grant experience points. It’s one of the fastest skills to train, especially at higher levels, and is often pursued for its efficiency in boosting overall account level or achieving specific quest requirements. Players typically burn logs on unlit fires or directly on the ground to gain XP. The experience awarded depends on the type of log used, with rarer and higher-level logs yielding more experience.

Who should use an OSRS Firemaking calculator?
Any OSRS player looking to train their Firemaking skill efficiently should consider using a calculator. This includes:

• New players aiming to reach specific Firemaking levels for quests or unlocks.
• Mid-game players seeking to quickly boost their Firemaking level for better combat stats or access to higher-tier activities.
• Ironman players planning their resource acquisition and training methods.
• Experienced players aiming for high Firemaking levels (e.g., 99 Firemaking) for the maximum XP rate or prestigious status.
• Players who want to budget their in-game currency (GP) by understanding the cost of training.

Common misconceptions about OSRS Firemaking include:

• That it’s only useful for quests: While quests are a common reason, high Firemaking levels also provide benefits like increased magic defence and can be part of slayer tasks.
• That it’s always expensive: Certain logs can be obtained cheaply or even free through various in-game activities, making it less costly than many assume.
• That it’s extremely click-intensive: While some methods involve more clicks, burning common logs like Yew or Magic can be relatively AFK (Away From Keyboard) with high XP rates.

OSRS Firemaking Formula and Mathematical Explanation

The core of the OSRS Firemaking calculator relies on understanding the experience curve in RuneScape. Each level requires a specific amount of cumulative experience to achieve. The calculation involves determining the total experience needed to go from your current level to your target level, and then dividing that by the experience provided by a single log of your chosen type.

Step-by-step derivation:

1. Experience for each level: The game defines a fixed experience requirement for each level. For example, level 2 requires 8 XP, level 3 requires 15 XP, and so on. The total experience needed to reach level ‘N’ is the sum of the experience required for all levels from 1 up to ‘N’.
2. Total XP Required: This is calculated as:
   Total XP = Cumulative XP at Target Level - Cumulative XP at Current Level
3. Logs Needed: Once the total XP is known, we determine how many logs are required.
   Logs Needed = Total XP Required / XP per Log
   (Ensure to round up to the nearest whole log, as you can’t burn fractions of logs).
4. Total Cost: This is a straightforward multiplication of the logs needed by the cost per log.
   Total Cost = Logs Needed * Cost Per Log (GP)
5. XP Per Hour & Time: These are estimates. A common benchmark for burning logs is around 3 seconds per log (including banking time, though this varies greatly).
   XP Per Hour = (XP per Log / Seconds per Log) * 3600
Time to Complete (Hours) = (Logs Needed * Seconds per Log) / 3600

Practical Examples (Real-World Use Cases)

Let’s illustrate how the OSRS Firemaking calculator can be used with practical examples.

Example 1: Training Yew Logs from Level 60 to 70

• Inputs:
  • Current Level: 60
  • Target Level: 70
  • Log Type: Yew Log (XP per Log: 90)
  • Cost Per Log (GP): 150
• Calculation Breakdown:
  • Cumulative XP at Level 60: ~34,310 XP
  • Cumulative XP at Level 70: ~80,188 XP
  • Total XP Required: 80,188 – 34,310 = 45,878 XP
  • Logs Needed: 45,878 XP / 90 XP/log ≈ 509.76 logs. Rounded up to 510 logs.
  • Total Cost: 510 logs * 150 GP/log = 76,500 GP
  • Estimated Time: (510 logs * 3s/log) / 3600s/hr ≈ 0.425 hours (approx. 25.5 minutes)
• Interpretation: To reach level 70 Firemaking from level 60 using Yew Logs, a player will need approximately 510 Yew Logs, costing around 76,500 GP, and taking roughly 25.5 minutes assuming a consistent burn rate.

Example 2: Aiming for 99 Firemaking with Magic Logs

• Inputs:
  • Current Level: 85
  • Target Level: 99
  • Log Type: Magic Log (XP per Log: 105)
  • Cost Per Log (GP): 300
• Calculation Breakdown:
  • Cumulative XP at Level 85: ~4,751,899 XP
  • Cumulative XP at Level 99: ~13,034,431 XP
  • Total XP Required: 13,034,431 – 4,751,899 = 8,282,532 XP
  • Logs Needed: 8,282,532 XP / 105 XP/log ≈ 78,881.26 logs. Rounded up to 78,882 logs.
  • Total Cost: 78,882 logs * 300 GP/log = 23,664,600 GP
  • Estimated Time: (78,882 logs * 3s/log) / 3600s/hr ≈ 65.7 hours
• Interpretation: Achieving the prestigious level 99 Firemaking from level 85 using Magic Logs is a significant undertaking. It requires nearly 79,000 Magic Logs, costing over 23.6 million GP, and will take approximately 66 hours of continuous burning. This highlights why players often seek cheaper logs or utilize alternative training methods for large XP gains.

Decision-making Guidance: This calculator helps you compare different log types. For instance, you can see if burning more expensive Magic logs is worth the significantly higher XP rates compared to cheaper Maple logs. It also aids in budgeting: knowing the total GP cost allows you to plan your finances or prioritize other activities if the cost is too high. For Ironman players, it aids in planning resource gathering.

Key Factors That Affect OSRS Firemaking Results

Several factors influence the accuracy and outcome of Firemaking calculations and the overall training experience:

• Log Type Choice: This is the most significant factor. Higher-level logs (Magic, Redwood) offer substantially more XP per log but are typically much more expensive. The choice directly impacts both the total number of logs needed and the total GP cost.
• Grand Exchange (GE) Prices: The cost per log fluctuates based on supply and demand on the GE. Using real-time GE prices in the calculator provides the most accurate cost estimation. Prices can be affected by updates, events, or player activity.
• XP Rates & Burn Speed: The calculator uses an estimated burn time (e.g., 3 seconds per log). Actual burn rates can vary slightly depending on player actions, reaction time, and whether a bank is nearby. Faster burning leads to higher XP/hour and less time spent.
• Banking Efficiency: For methods requiring banking (e.g., using unique log types or specific locations), the time spent travelling to and from the bank significantly impacts the XP per hour. Highly efficient banking setups can reduce the total time required.
• In-Game Events and Boosts: Occasionally, Jagex runs events that provide bonus XP or reduced costs for certain skills. These events are not factored into standard calculations but can drastically speed up or cheapen the training process.
• Alternative Training Methods: While this calculator focuses on standard log burning, players might use methods like Wintertodt for Firemaking XP alongside other rewards (like supplies and GP), which drastically alters the cost-effectiveness and XP rates compared to pure log burning. The calculator assumes direct log burning.
• Player Goal and Motivation: The ‘best’ method isn’t always the fastest or cheapest in pure GP terms. A player aiming for specific quest requirements might only need a few levels and opt for the quickest method regardless of cost, whereas someone aiming for 99 might prioritize minimizing GP expenditure.

Frequently Asked Questions (FAQ)

Q1: What is the fastest way to train Firemaking in OSRS?

Generally, burning the highest-level logs you can afford (like Magic or Redwood logs) offers the highest XP per log and thus potentially the fastest XP rates. However, the Wintertodt boss is also a popular and often cheaper method, especially for early-to-mid levels, as it provides supplies and other rewards alongside Firemaking XP.

Q2: Is Firemaking expensive to train?

It can be, especially if you use high-level logs like Magic or Redwood logs, which are often costly on the Grand Exchange. However, training with lower-level logs like Willow or Maple is significantly cheaper, albeit slower. The Wintertodt is often considered a cost-effective or even profitable way to train Firemaking, especially at lower levels.

Q3: Which logs give the most XP in OSRS?

Redwood logs provide the highest experience per log (120 XP), followed closely by Magic logs (105 XP). Yew logs offer 90 XP, Maple logs 75 XP, and so on, down to Normal logs at 30 XP.

Q4: How much XP is needed for level 99 Firemaking?

Reaching level 99 in Firemaking requires a total of 13,034,431 experience points. This is a significant amount, making it one of the higher XP requirements for a non-combat skill.

Q5: Can I use this calculator for the Wintertodt?

This calculator is primarily designed for calculating XP and costs based on burning individual logs directly. It does not directly calculate the XP rates or GP efficiency of the Wintertodt, as that involves a different minigame mechanic with variable rewards and inputs.

Q6: What are the best logs to burn for profit?

Generally, no log type is consistently profitable for burning as a primary money-making method. The XP gained rarely outweighs the cost of the logs when bought directly from the GE. Wintertodt can sometimes be profitable due to the supply crates it drops, but this is RNG-dependent.

Q7: How accurate are the XP per hour and time estimates?

The estimates are based on a fixed time per log (around 3 seconds). Actual XP per hour can vary significantly based on your efficiency, banking speed, and whether you’re actively playing or doing slightly more AFK methods. The time to complete is a direct calculation based on logs needed and the estimated burn time.

Q8: Do different methods of burning logs yield different XP?

No, the experience gained per log is consistent regardless of how or where you burn it (e.g., on the ground, on a portable brazier, or using a specific fire pit). The differences lie in the cost of the logs and the efficiency of burning/banking them.
