Facebook Ads Cost Per Purchase Benchmarks in Singapore

Introduction — the main story

Singapore’s cost-per-purchase profile ran hotter and much choppier than the global benchmark across the 12-month window. 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 All industries in Singapore compared to the global benchmark.

In plain terms: Singapore started the year with elevated costs (roughly SGD 71 in July 2025), peaked in September (about SGD 92), then fell steadily into a low-thirties trough by May–June 2026. The rhythm shows strong Q3/Q4 pressure followed by a sharp decline through early- to mid‑2026, with several abrupt month-to-month reversals.

The story in the data

Cost per purchase in Singapore averaged about SGD 59.3 over the period, ranging from a high of ~SGD 91.9 (September 2025) to a low of ~SGD 32.7 (May–June 2026). The series began at ~SGD 71.4 (July 2025) and finished at ~SGD 32.7 (June 2026), a decline of roughly 54% from start to end.

Notable moves: August→September 2025 climbed from ~SGD 80 to ~SGD 91 (+15%), while February→March 2026 jumped from ~SGD 40.9 to ~SGD 72.3 (+77%). The largest single drop came March→April 2026 (≈ −53%), and the sustained low in April–June 2026 held near ~SGD 32–34. Monthly volatility (standard deviation) was large — roughly SGD 21–22 — indicating swings equal to about 36% of the Singapore mean.

By contrast the global (baseline) median sat near SGD 49.9 across the same months, with a much tighter monthly standard deviation (~SGD 3.3). That baseline helps set the scale for comparison.

Seasonal and monthly dynamics

The pattern reads like a classic high‑pressure selling season followed by post-season cooling. Q3 (July–September 2025) showed the strongest lift, peaking in September. Q4 contained a softer dip and a brief rebound (November and December were mid-range). January–February 2026 were relatively subdued (~SGD 40 each), followed by a sharp spike in March and then a sustained decline through April–June 2026 into the low‑thirties.

This rhythm mirrors heavier competition and higher bid pressure in late summer and early autumn, then a pronounced taper and rebalancing in the first half of the next year — punctuated by an outlier spike in March.

Country vs. Global

Across the period Singapore ran above the global benchmark on average (+~19% vs the global median of ~SGD 49.9). The gap was most extreme in Q3–Q4 2025: Singapore traded at roughly 45–73% above baseline in July–October and still ~19–46% above in November–December. That advantage flipped in parts of 2026: January–February were ~18% below baseline, and April–June sat ~24–31% below global medians. Singapore’s cost-per-purchase trajectory was substantially more volatile than the global trend — roughly six to seven times the baseline monthly variability — creating wider gaps as much as +73% and as deep as −31% month-to-month relative to the baseline.

Facebook Ads benchmarks, CPC trends, CPM analysis and CTR performance narratives all find echoes here: Singapore’s country-specific ad costs for all industries displayed concentrated seasonal peaks and deeper troughs than the global average, producing a distinctive, stop‑start cadence for industry ad performance.

Understanding Cost Per Purchase benchmarks for All industries in Singapore provides a clear picture of how country-specific ad costs can diverge from global patterns and why Singapore’s year looked both uplifted and more volatile across this advertising cycle.
