Accra, Ghana//-The year-on-year inflation rate measured by the Prime Building Cost Index (PBCI) has increased to 5.1 percent in September 2026 from 4.6 per cent in August 2026.
By this, building costs were 5.1% higher than a year ago and 0.03% higher than in August 2026.
Plant and equipment costs went up 19.1% over the year and were the main pressure point.
The monthly change rate for September 2026 was 0.03 per cent.
In a press release, the Ghana Statistical Service explained that the index tracks the prices of key construction inputs such as building materials, labour, and equipment over time, indexed to the 2023 base year, which is set at 100.
“In simple terms, the PBCI shows whether it is becoming more expensive or cheaper to build compared to a previous period. PBCI is used by key stakeholders including investors, developers, contractors, and policy makers to negotiate contracts, adjust bids, budget effectively, and monitor inflation trends in the building sector”, it said.
