Royalty inputs
Pick your jurisdiction and mineral, enter the gross market value of the mineral, and confirm the royalty rate. Every rate is an editable, planning-grade default — confirm it against the official source before you rely on it.
The value of the mineral sold, before deductions. Enter it in your own currency — the royalty is a percentage, so the result is in the same currency.

How this is calculated
Royalty due = gross value × royalty rate. Net proceeds = gross value − royalty − any separate statutory levy (for example, Tanzania's 1% clearing-house inspection fee is shown on its own line, not folded into the royalty). Where a jurisdiction uses a profit- or price-based formula — South Africa (0.5%–5% refined / 0.5%–7% unrefined), Zambia copper (4%–10% by price), and Burkina Faso and Zimbabwe gold — no single flat rate applies, so the tool shows the statutory band and asks you to enter your effective rate. A missing rate is never treated as 0%.

Frequently asked questions
How is a mining royalty calculated?

A mineral royalty is charged as a percentage of the gross market or sale value of the mineral. This calculator multiplies the gross value you enter by the royalty rate for your country and mineral, then shows the royalty due and your net proceeds after it. Where a separate statutory levy applies, such as Tanzania's 1% clearing-house inspection fee, it is shown as its own line.

Are the royalty rates current?

The rates are planning-grade defaults drawn from each country's Mining Code or Finance Act and are shown with a review date. They change at budget and several countries use price- or profit-based sliding scales, so always confirm the current rate with the official source shown before you rely on it. It is not legal or tax advice.

Which countries and minerals are covered?

It covers 18 African mining jurisdictions — Ghana, Tanzania, South Africa, Zambia, DR Congo, Zimbabwe, Botswana, Namibia, Nigeria, Kenya, Mali, Burkina Faso, Egypt, Sierra Leone, Côte d'Ivoire, Liberia, Madagascar and Gabon — across gold, diamonds, copper, cobalt, coltan and other minerals. The mineral list changes with the country you pick.

Why does it ask me to enter the rate for some countries?

Where a country uses a profit formula or a price-linked sliding scale — South Africa, Zambia copper, and the gold scales in Ghana, Zimbabwe, Mali, Burkina Faso, Côte d'Ivoire, Egypt and Gabon — no single flat rate applies, so the tool shows the statutory band and asks you to enter your effective rate rather than guessing. A missing rate is never treated as zero.
