spell level × caster level × 1,800 gp - Continuous item:
spell level × caster level × 2,000 gp × duration multiplier - Bonus item:
bonus² × base price factor - Craft gold:
market price × crafting gold percentage - XP cost:
market price ÷ XP rate - Crafting time:
ceiling market price ÷ daily craft rate
How to Use This Calculator
Enter a clear item name first. Select the item category that best matches the intended magic item. For spell based items, enter spell level and caster level. For bonus items, use the spell level box as the bonus value. Add charges when pricing wands or limited charge items.
Choose duration, slot, and ability multipliers carefully. These options have strong effects on final price. Add masterwork cost, special material cost, or extra flat cost when the base object has value before enchantment. Use market adjustment to raise or lower the result for campaign economy, rarity, setting limits, or special story value.
Press the calculate button. The result appears above the form. Use the CSV button to export spreadsheet data. Use the PDF button to save a report for players or campaign notes.

Advanced Guide to Magic Item Pricing
Planning the Item
Magic item creation works best when the goal is clear. Start with the exact effect. Decide if the item copies a spell, grants a bonus, stores charges, or adds a constant power. A clear category keeps the price fair. It also helps the Dungeon Master compare the item with published gear.
Reading the Cost
The market price is the normal buying value. Crafting gold is the amount usually paid by the creator. Experience cost shows the personal investment needed for creation. Crafting time estimates the number of workdays. These values help players plan downtime. They also help the campaign avoid sudden power jumps.
Handling Multipliers
Multipliers matter a lot. Continuous effects can become expensive when the spell duration is short. A power that uses no proper body slot may also cost more. Added abilities can increase price because one item replaces several items. Use these controls to model complex enchanted objects.
Balancing Custom Effects
Not every custom item should use a formula without judgment. Some effects are stronger in play than their spell level suggests. Flight, action economy, invisibility, teleportation, and broad immunities can change encounters. Raise the market adjustment when an effect removes important limits. Lower it only for narrow, risky, or story bound items.
Campaign Economy
Treasure level affects game balance. A low magic campaign may need higher prices or limited crafting access. A high magic campaign may allow common crafting, shops, and faster downtime. This calculator gives structure, but it should not replace table rules. Use the result as a strong starting point.
Player and DM Review
Share the result before adding the item to play. Review the formula, cost, requirements, and expected use. Compare it with similar published items. Adjust the final price if it gives too much power for its level. Good pricing keeps custom items exciting, useful, and fair.
FAQs
1. Can this calculator replace Dungeon Master approval?
No. It provides structured estimates. The Dungeon Master should still review unusual effects, campaign wealth, spell access, body slots, and balance concerns.
2. What should I enter for bonus items?
Use the spell level or bonus field as the bonus value. For example, enter 3 for a +3 resistance, armor, weapon, or skill item.
3. Why does duration affect continuous items?
Short duration spells become stronger when made continuous. The multiplier raises the price to reflect that increased long-term usefulness.
4. How are wand charges handled?
A standard wand uses 50 charges. If you enter fewer or more charges, the calculator scales the wand price proportionally.
5. What does the slot multiplier mean?
Items using a proper body slot are cheaper. Slotless or unusual slot items cost more because they avoid normal equipment limits.
6. Why add masterwork cost?
Weapons, armor, and certain crafted objects may need a valuable base item before magic is added. This field includes that cost.
7. What is market adjustment?
Market adjustment changes the final price by percentage. Use it for rarity, campaign economy, story limits, or effects stronger than expected.
8. Why is crafting time rounded up?
Partial crafting days still require downtime. The calculator rounds upward so any remaining value counts as another workday.
