Formula

How the calculator models your portfolio.

Monthly estimate = Σ(mine count × base rate × level multiplier) × blended daily boost.

The level multiplier is 1 + 0.01 for every level above level 1. A level 10 mine therefore uses 1.09× its level-one reference rate.

For daily boost coverage, boosted hours use the published 20× multiplier while unboosted hours remain at 1×. Eight boosted hours per day produce a blended multiplier of approximately 7.33× across the full day.

03

Rarity

Small portfolios can be far from the expected mix.

A 1% Diamond chance does not guarantee one Diamond within the first 100 claims. Every claim is a random outcome, so short streaks can look unusually lucky or unlucky.

Use the TerraMine Luck Score to compare your actual mix with the published distribution, or open the earnings calculator for a complete rent estimate.

Plain-English answers

Frequently asked questions

What is the rarest TerraMine mine?

Diamond is the rarest published mine type at approximately 1% of properties and earns 4× the Rock multiplier.

Does 100 mines guarantee a Diamond?

No. A 1% probability describes the long-run distribution, not a guarantee within any specific set of 100 claims.

Are the dollar rates guaranteed?

No. They are community reference values used for planning. TerraMine can change rates, boosts and future payout terms.
