Your numbers and contact details reach Darikoda by email and are used to build your leak map. Nothing else, and no marketing list. Read the privacy notice.
Choose one cost to investigate first.
A high fuel figure calls for a check of deliveries, issues and machine use. Idle hours call for a look at the delays and assignments behind them.

What does the calculator estimate?
It applies your chosen rates to annual fuel spend, idle machine hours, breakdowns and, for construction and civils, money tied up in payment certificates. Each result shows its calculation.
Which figures should I use?
Use your fleet size and diesel spend, then adjust the rates to match your records. The starting values are examples you can change.
What happens when I send my numbers?
Darikoda uses them to start a conversation about the costs you want to investigate. The free 30-minute audit helps identify the records and practical steps to focus on first.
Patterns described here are drawn from extensive field audits and industry research across Ghana's mining, construction, roadworks, and quarry sectors. No specific operator is named or identifiable.
