Facebook Ads Cost Per Purchase Benchmarks for Construction

Introduction

Across all countries, Construction shows a high-cost, high-volatility pattern for Facebook Ads purchase outcomes. Cost Per Purchase (CPP) averaged $169 over the past 12 months, far above the global benchmark’s $49, with a dramatic March spike followed by a steady slide into October. The year opened elevated in December, surged into March, then cooled quarter by quarter, ending at the yearly low. This analysis is based on $3B worth of advertising data from our dataset, which provides strong directional benchmarks. This analysis explores ad performance trends for Construction across all countries compared to the global benchmark.

The story in the data

Construction CPP began at $129 in November 2024 and landed at $92 in October 2025, a 29% decline end to end. The high point came in March at $314—more than triple the starting level—while October marked the low at $92. Across the period, CPP averaged $169, ranging from $92 to $315.

Month-to-month shifts were pronounced. December jumped by $106 versus November, and February to March lifted another $161 to the peak. The sharpest pullback followed in April (−$123), after which costs normalized and drifted down in smaller steps through summer. Average absolute monthly volatility was $54, roughly 32% of the average CPP—21 times the global benchmark’s monthly swing of about $2.6 (near 5% of its average).

Seasonal and monthly dynamics

Seasonally, the rhythm was clear:

• Q4 2024 ran elevated, averaging $183, with December at $236.
• Q1 2025 held steady in January–February before a March breakout to $315, the period’s top.
• Q2 2025 retrenched to a tighter $169–$192 band (average $183).
• Q3 2025 compressed further, averaging $134 with three months clustered near $130–$137.
• Early Q4 2025 cooled sharply: October fell to $92, the low for the year.

This contour—strength into late Q4, a Q1/March crest, and a gradual step-down into Q3–Q4—is consistent with competitive cycles often seen in paid social. While CPC trends, CPM analysis, and CTR performance describe upper-funnel movements, the CPP lens here highlights the downstream cost required to convert purchases in Construction across all countries.

Country vs. Global

Construction’s CPP across all countries consistently sat above market. On average it was 3.4x the global benchmark (+242%). The gap was widest in March (6.0x: $315 vs. $52) and narrowest in October (2.1x: $92 vs. $43). By contrast, the global benchmark was flat to slightly positive over the same window: it started at $42.61 and finished at $43.33 (+2%). The global high was a modest $53.84 in February, with a $42.61 low in November—an $11 range versus Construction’s $223 range, underscoring how much more volatile Construction purchase costs were across all countries.

Closing

In sum, Facebook Ads benchmarks for Cost Per Purchase in the Construction industry across all countries show a pronounced March peak, broad seasonality, and substantially higher, more volatile country-agnostic ad costs versus the global benchmark. Understanding CPP benchmarks—alongside CPC trends, CPM analysis, and CTR performance—helps frame industry ad performance and compare country-specific ad costs to global patterns for Construction.
