What is the OSRS Mahogany Homes Calculator?

The OSRS Mahogany Homes Calculator is a specialized utility designed for Old School RuneScape players looking to train Construction through the Mahogany Homes minigame. Unlike traditional construction methods that involve building and removing furniture in a Player Owned House (POH), Mahogany Homes sends players across Gielinor to repair furniture for various NPCs.

Efficiency-minded players use this OSRS Mahogany Homes Calculator to balance their budget and time. Mahogany Homes is significantly more plank-efficient than traditional training, often saving players 50% to 70% on total plank costs, though it yields lower experience rates per hour. This tool helps you decide if the cost savings are worth the extra time spent traveling.

OSRS Mahogany Homes Calculator Formula and Mathematical Explanation

The logic behind the OSRS Mahogany Homes Calculator relies on weighted averages. Because every contract involves a different number of repairs and different furniture types, we use statistical averages provided by community testing.

The core formula used is:

Total Planks = (Target XP – Current XP) / (Base XP per Plank * (1 + Outfit Bonus))

Where "Base XP per Plank" includes the completion bonus awarded at the end of each contract divided by the average number of planks used.

Variable	Meaning	Unit	Typical Range
Current XP	Player's starting experience	XP	0 – 200,000,000
Target Level	Desired Construction level	Level	1 – 99
Plank Tier	The material being used	Type	Oak, Teak, Mahogany
Outfit Bonus	Bonus from Carpenter's gear	%	0% – 2.5%

Practical Examples (Real-World Use Cases)

Example 1: The Road to 83. A player has 50 Construction (101,333 XP) and wants level 83 (2,673,114 XP) for POH upgrades. Using Teak planks with no outfit: The OSRS Mahogany Homes Calculator determines they need approximately 8,961 Teak planks. At 800 GP per plank, this costs ~7.1M GP and takes roughly 35 hours.

Example 2: Efficiency Maxing. A player with 90 Construction aiming for 99 using Mahogany planks and a full Carpenter's outfit. They need 7,512,143 more XP. The OSRS Mahogany Homes Calculator shows they need 17,043 Mahogany planks, costing ~33M GP but earning enough points for the Plank Sack and Amy's Saw.

Key Factors That Affect OSRS Mahogany Homes Calculator Results

• Contract Randomization: Each contract has a variable number of repairs (typically 8-14). The calculator uses averages, so your actual results may vary by 1-2%.
• NPC Contact Spell: Using the Lunar spellbook's NPC Contact to get new assignments significantly increases contracts per hour, reducing the time calculated by the OSRS Mahogany Homes Calculator.
• Teleport Efficiency: Having teleports to Falador, Varrock, Ardougne, and Hosidius (Xeric's Talisman) is vital. Slower travel increases the "Est. Time" result.
• Supply Run Management: Using a Servant or the Plank Sack reward affects how often you visit a bank, impacting your XP/hr.
• Carpenter's Outfit: The 2.5% bonus seems small, but over millions of XP, it saves hundreds of expensive Mahogany planks.
• Server Ping: Construction is a click-intensive skill. Higher latency can reduce your effective contracts per hour compared to the OSRS Mahogany Homes Calculator defaults.

Frequently Asked Questions (FAQ)

Is Mahogany Homes better than building tables?

It depends on your goal. Mahogany Homes is much cheaper and more click-intensive but offers roughly 1/3 to 1/2 the XP/hr of traditional methods. Use this OSRS Mahogany Homes Calculator to compare the gold saved.

How many points do I need for the Plank Sack?

The Plank Sack costs 350 Carpenter Points. Our OSRS Mahogany Homes Calculator shows you how many planks it will take to reach that point total.

Does the Crystal Saw work here?

The Crystal Saw provides a +3 visible boost for building, but it does not increase the XP gained per plank in Mahogany Homes.

Is the Carpenter's Outfit worth getting?

If you are going for 99 or 200m XP, yes. For level 83, the time spent earning points for the outfit often exceeds the time saved by the bonus XP.

What is the average XP per hour?

With Mahogany planks and high efficiency, you can expect 200k-220k XP/hr. Teak planks usually yield 140k-160k XP/hr.

Do I need steel nails?

Steel nails are required for Oak and Teak contracts, but not Mahogany. Our calculator focuses on the primary cost driver: the planks.

Can I do this on an Ironman?

Absolutely. It is the meta-method for Ironmen to save on gathered planks. The OSRS Mahogany Homes Calculator is essential for planning your woodcutting grind.

What magic level do I need?

Level 67 Magic is recommended for NPC Contact, though not strictly required if you don't mind walking back to Amy in Falador.
