Firemaking Calculator OSRS

Choose Your Firemaking Destination — We'll Build the Best Route. Calculate logs needed, Wintertodt games, GP cost, and estimated training time. Compare regular logs, pyre logs, and Wintertodt side by side with Pyromancer outfit bonuses. or use the main construction calculator OSRS to plan your full 1-99 journey.

Whether you're burning willows for speed, running Wintertodt for profit, preparing pyre logs for Prayer, or planning an efficient path to 99, this calculator handles every Firemaking method with accurate XP rates and GP cost estimates.

Rather than starting with log types, begin with player objectives. Each path dynamically changes calculator recommendations.

Maximum XP Per Hour

Burn Magic Logs (303.8 XP each) or Redwood Logs (350 XP each) for the fastest XP rates. Expect 150K–175K XP/hr with efficient line burning. Cost is high but time is minimized.

Lowest GP Cost

Willow Logs cost as little as 20 GP each while providing 90 XP. At ~500 logs/hr, that's 45K XP/hr for almost nothing. The most budget-friendly route to 99.

Profit While Training

Wintertodt after level 50 provides Firemaking XP while earning supply crates worth thousands of GP. The only Firemaking method that generates profit rather than consuming GP.

Ironman Progression

Ironmen should bank logs from Woodcutting and burn them. Wintertodt is especially powerful for early Ironman accounts, providing seeds, herbs, ores, and other useful resources from supply crates.

Relaxed AFK Sessions

Line burning any log type in long rows at the Grand Exchange is semi-AFK. Wintertodt requires periodic attention but offers longer sessions between inputs.

Instead of listing methods individually, compare them by performance. The official Firemaking calculator supports multiple categories including regular logs, pyre logs, and XP modifiers, while Wintertodt remains one of the most efficient overall methods for many accounts.

Organize progression around meaningful checkpoints. Each milestone includes recommended method, approximate materials, time estimate, and unlocks gained.

Unlocking Oak Logs

At level 15, Oak Logs become available at 60 XP each. A significant jump from regular logs (40 XP). Burn approximately 150 oaks to reach level 30 for Willow Logs. Time: ~30 minutes. Cost: ~2,250 GP.

Preparing for Wintertodt

Reach level 50 to unlock Wintertodt. From level 30, burn Willow Logs (~1,100 willows needed). Time: ~2.2 hours. Cost: ~22,000 GP. Many players rush to 50 specifically for Wintertodt access.

Moving to High-Tier Logs

At level 60+, Yew Logs (202.5 XP) become efficient. At level 75, Magic Logs (303.8 XP) offer the fastest non-Redwood rates. Expensive but fast.

Reaching Achievement Diary Goals

Multiple Achievement Diaries require Firemaking levels: Level 49 for Desert Medium, Level 65 for Kandarin Hard, Level 79 for Lumbridge Elite. Plan your training around these milestones.

Planning for Level 99

From level 90, you need ~8.2M XP. With Redwood Logs (350 XP each), that's ~23,400 logs and ~47 hours. With Wintertodt, roughly 1,600-2,000 games over ~320-400 hours. Most players use a combination.

Instead of only comparing XP, compare value. For every log: XP each, required level, approximate cost, GP per XP, and best use case.

Normal Logs

40 XP • Level 1 • ~100 GP each • 2.5 GP/XP • Best for levels 1-15. Cheap and readily available. Not worth buying in bulk.

Oak Logs

60 XP • Level 15 • ~150 GP each • 2.5 GP/XP • Good for early training. Slightly better XP than normal logs with similar cost efficiency.

Willow Logs

90 XP • Level 30 • ~20 GP each • 0.22 GP/XP • Best cost efficiency in the game. Extremely cheap with decent XP per log.

Maple Logs

135 XP • Level 45 • ~30 GP each • 0.22 GP/XP • Similar efficiency to willows with higher XP. Great mid-level option.

Yew Logs

202.5 XP • Level 60 • ~250 GP each • 1.23 GP/XP • Good XP per log. Moderately expensive. Better for faster training than budget.

Magic Logs

303.8 XP • Level 75 • ~950 GP each • 3.13 GP/XP • Second-highest XP. Very expensive. Use only when speed matters more than GP.

Redwood Logs

350 XP • Level 90 • ~400 GP each • 1.14 GP/XP • Highest XP per log with excellent cost efficiency. The best high-level option.

Wintertodt requires 50 Firemaking and rewards players with Firemaking XP, supply crates, and the exclusive Pyromancer outfit, which increases Firemaking XP gained when the full outfit is worn.

When Should You Switch to Wintertodt?

As soon as you reach level 50 Firemaking. Many players rush to 50 with willows specifically for Wintertodt access. Low-level accounts benefit most from supply crate rewards since loot scales with other skill levels.

Games Needed to Reach Your Goal

XP per game scales with your Firemaking level. At level 50: ~480 XP/game. At level 90: ~640 XP/game. From 50 to 99, expect roughly 1,800-2,200 games depending on points earned per game.

Expected Supply Crates

You earn 1 supply crate per 500 points. Most players average 500-750 points per game, earning 1-2 crates. Crates contain seeds, herbs, ores, fish, and unique items.

Pyromancer Outfit Progress

The Pyromancer outfit drops from supply crates. Full set provides +2.5% Firemaking XP. Pieces: Pyromancer Hood, Garb, Robe, and Boots. Average ~40-60 crates per piece.

Firemaking XP From Wintertodt

XP formula: Base XP + (Firemaking Level × 4) per game. Higher Firemaking = more XP per game. At level 99, each game gives approximately 680+ XP.

Burn Banked Logs First

Check your bank for logs from Woodcutting, PvM drops, and clue scrolls. Burning banked logs costs zero GP and gives the same XP as purchased logs.

Use Wintertodt for Profit

Wintertodt is the only Firemaking method that generates GP. Supply crates average 10K-30K GP depending on your other skill levels. High-level accounts earn significantly more.

Compare Live Log Prices

Grand Exchange prices fluctuate daily. Willow logs sometimes drop to 5 GP each. Check current prices before bulk buying — a few GP difference per log matters when buying thousands.

Take Advantage of XP Bonuses

The Pyromancer Outfit provides +2.5% XP. This saves approximately 325K logs across the entire 1-99 grind. Get it from Wintertodt supply crates as early as possible.

Choose Logs Based on GP per XP

Willow Logs at 0.22 GP/XP are 14× cheaper than Magic Logs at 3.13 GP/XP. The time difference is significant, but the cost difference is enormous. Balance speed with budget.

Experience Formula

Uses the official OSRS experience table. Each level requires progressively more XP — level 92 is the halfway point to 99 at 6.5M XP.

Remaining XP Calculation

Target Level XP − Current XP = XP Remaining. If you enter custom XP, it overrides the level-based calculation for precise results.

Method Availability Check

The calculator filters methods by your current level. Wintertodt requires level 50, Redwood Logs require level 90. Only available methods are shown.

Log Requirement Estimation

Logs Needed = ⌈XP Remaining ÷ XP per Log⌉. Adjusted for Pyromancer outfit bonus when enabled (+2.5% effective XP per log).

GP Cost Projection

Total Cost = Logs Needed × Current GE Price per Log. Wintertodt shows estimated profit from supply crates instead of cost.

Training Time Forecast

Hours = Logs Needed ÷ Logs per Hour. Standard rates: ~500 logs/hr for line burning, ~400/hr for pyre logs, ~5 Wintertodt games/hr.

• Burning expensive logs without comparing GP per XP — Magic Logs cost 14× more per XP than Willow Logs.
• Ignoring Wintertodt after level 50 — It's profitable, provides good XP, and gives useful resources.
• Selling banked logs before checking XP value — Free XP is always worth more than sell price.
• Forgetting Pyromancer outfit bonuses — 2.5% adds up to hundreds of thousands of XP saved.
• Choosing speed when profit is the better option — Wintertodt earns GP while training.
• Training without estimating total costs — Use the calculator to plan before buying.
• Ignoring Ironman-specific resource planning — Ironmen should coordinate Woodcutting and Firemaking.
