How this is calculated
Royalty = gross × royalty%. Cost oil = min(recoverable costs, ceiling% × post-royalty revenue). Profit oil = post-royalty revenue − cost oil. Contractor profit = profit oil × contractor share; government profit = the rest. Tax = contractor profit × tax%. Contractor net = cost oil + contractor profit − recoverable costs − tax. Government take = royalty + government profit + tax. As a check, contractor net + government take + total costs always equals gross revenue.

Frequently asked questions
How does the Oil & Gas Revenue Calculator model a production-sharing contract?

It follows the standard PSC waterfall. First royalty is taken from gross revenue. From the revenue left after royalty, recoverable costs are recovered as cost oil, capped by a cost-recovery ceiling you set. What remains is profit oil, split between the contractor and the government by the share you enter. An optional profit tax is applied to the contractor's profit oil. The contractor's net is cost oil plus its profit-oil share, minus its costs and tax; the government take is royalty plus its profit-oil share plus tax.

What is cost oil and the cost-recovery ceiling?

Cost oil is the portion of production revenue a contractor keeps to recover its operating and capital costs. Most PSCs cap it — for example at 60% or 70% of post-royalty revenue — so not all costs can be recovered in one period. The tool recovers the lower of your recoverable costs and the ceiling you set, and carries the rest as unrecovered.

Are these real fiscal terms for my country?

No — every rate is your input. PSC terms differ by country, licence round and contract and are often confidential. Enter the royalty, cost-recovery ceiling, profit split and tax from your own contract or your regulator's model PSC. This is a planning model, not the terms of any specific agreement, and not tax or legal advice.

Is it free?

Yes, it is completely free with no signup and runs on any phone or computer. It is built for African oil and gas contexts but works for any set of PSC terms you enter.
