Facebook Ads Cost Per App Install Benchmarks for Public Administration

Introduction

The main story: app-install costs were generally moderate for much of the 12‑month window, then ended the period with a dramatic spike. The global COST_PER_APP_INSTALL benchmark averaged about $21.84 over the period, but values ranged widely — a low near $9.36 in December 2025 and a surge to $96.91 in July 2026. Volatility was notable, with a string of mid‑double‑digit month‑to‑month swings and one extreme jump at the end. 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 Public Administration in All countries available compared to the global benchmark. (Note: an industry‑specific time series for Public Administration / All countries was not supplied; the narrative below focuses on the available global COST_PER_APP_INSTALL baseline.)

The story in the data

The baseline series started at $9.95 in July 2025 and finished at $96.91 in July 2026 — nearly a tenfold increase from the opening month. Across 13 monthly medians the central tendency was about $21.8 per app install. The minimum occurred in December 2025 ($9.36) and the first clear peak appeared in February 2026 ($30.13). After a return to mid‑teens through spring (March–June 2026 averaged roughly $16–$19), July 2026 produced an outsized high of $96.91.

Month‑to‑month moves were frequent and sometimes sharp: typical increases of 20–30% in late‑2025 (July→August→September), a near 37% rebound into January, a 135% jump into February, and a 45% retreat into March. Including the July spike, average absolute month‑to‑month change was roughly 77%; excluding that final outlier the average swing settles nearer to 33%. Those figures underline a baseline that is usually bumpy and punctuated by rare but extreme shifts.

Seasonal and monthly dynamics

Seasonal rhythm is visible: a softer late‑year trough in December 2025 coincides with the period’s lowest CPI, followed by a Q1 lift that peaks in February 2026. Spring months (March–May) see stabilization in the mid‑teens, and early summer (June) holds steady before the abrupt July escalation. The pattern reads as a quiet Q4 trough, a Q1 rebound, a steadier Q2, and then an exceptional outlier at the start of Q3.

These monthly patterns suggest recurring periods of lower competition or pricing pressure (late Q4) and concentrated cost jumps in early Q1 and mid‑year — the latter of which produced the largest deviation from the baseline.

Country vs. Global

Because a specific Public Administration series for All countries was not provided, direct numerical gaps versus the global baseline cannot be calculated here. Using the baseline as the global reference point, the dataset shows how industry ad performance can swing between single‑digit to triple‑digit CPI values within a year. Descriptively, the baseline exhibits episodes of being both below‑average (December lows near $9–$12) and well‑above average (February and July peaks), illustrating how country‑specific ad costs and industry ad performance can diverge from an aggregate norm.

Understanding Facebook Ads Cost Per App Install benchmarks for Public Administration in All countries available helps advertisers evaluate volatility in country-specific ad costs and compare industry ad performance to broader CPM, CPC trends and CTR performance signals.
