🏰 OSRS Construction training can get expensive fast — here’s how to avoid wasting GP…
When I first started training Construction in OSRS, I made every mistake possible. I bought oak logs instead of planks. I didn't use a demon butler. I trained at the wrong levels with inefficient methods. I wasted over 15M GP before I figured out the right approach.
That's when I learned: Construction training isn't just about buying planks and building. Here's what most players get wrong:
- Different levels need different methods — Oak Chairs (33-52), Oak Larders (52-74), Oak Dungeon Doors (74-99)
- Mahogany Homes saves 30-40% on planks — Lower XP rates but significantly cheaper. Great for ironmen and budget players
- Demon butler is worth the cost — 10k per trip but saves hours of running to the bank
- GE prices fluctuate constantly — Oak planks range from 300-600gp, mahogany from 1,500-2,500gp
This calculator helps you plan your Construction training from 1-99. Select your method, enter your current level, and get exact plank counts, costs, and estimated time. No more wasted GP.
📖 How to Use This OSRS Construction Calculator

💡 Pro tip: Always check current GE prices before buying. Oak planks vary between 300-600gp depending on market.
📋 Real-World OSRS Construction Examples
🏠 Budget 1-99 (Oak)
Oak Larders/Dungeon Doors → 85,000 planks → ~18-25M GP → ~60-80 hours
⚡ Fastest 1-99 (Mahogany)
Mahogany Tables → 38,000 planks → ~55-75M GP → ~12-15 hours
⚠️ My Costly Mistake
Bought logs instead of planks on first attempt → Wasted 2M GP
💡 5 OSRS Construction Tips I Wish I Knew
- Use a demon butler for all plank training. 10k GP per trip is worth the time saved. Without a butler, you'll spend 3x longer banking.
- Build oak dungeon doors from 74-99. 600 XP per build, 10 planks each. It's the best XP/plank ratio for oak training.
- Mahogany Homes is great for ironmen. Uses 30-40% fewer planks. The plank sack and Carpenter's outfit are worth getting.
- Buy planks, not logs. Sawmill fees add up. Planks are usually cheaper than logs + fee on GE.
- Train during off-peak hours. Lower ping = faster banking = higher XP rates. I gained 50k XP/hour extra at 3 AM.
⚠️ IMPORTANT NOTE: Grand Exchange prices fluctuate constantly. This calculator uses current market estimates. Always verify plank prices before buying in bulk. Prices can change significantly during double XP weekends or after game updates.
