Use this tool to calculate the optimal route to upgrade an Armor or Level 4 Weapon from +4 to +7. Enriched cost is the cost of a single enriched ore, in zeny. Assuming the enriched ores are bought while discount boxes are available, 3m corresponds to a price of ~150m/1k kafra points.

This calculator includes the cost of elu (or ori) used to get weapons from +0.

Costs for +8/9/10 are from +0, assuming enriched hammer is available and is used whenever possible - don't upgrade +7->9 without enriched hammer.

All costs assume average luck, individual results will vary widely.

The costs for +9 assume you continue using enriched if it falls below +7. This is not the optimum strategy for items so cheap that going +6-7 is cheaper with normal elu - for those items, you should cancel out of the conversation with Enriched Hammer and return to using normal elu to upgrade it (seriously, that's how the math works out)
