Understanding Prevailing Wage Trends and Analytics

A rate schedule tells you what labor costs today. Historical trend data tells you what it will cost in Year 3 of a multi-phase project — and that difference can determine whether your Pro Forma holds or bleeds.

Why Historical Rates Matter

Most prevailing wage tools stop at “what is the rate today.” For a contractor or owner estimating a 24-month project, that single data point is insufficient. NYC prevailing wage rates increase annually — sometimes modestly, sometimes significantly depending on negotiated CBA escalations.

Historical data enables three critical analytical tasks:

Forecasting future escalation for multi-year project budgets
Benchmarking one trade against others to identify labor cost anomalies
Validating whether a contractor's submitted rates have kept pace with published prevailing wages

How WageHound Calculates Trend Metrics

The WageHound Analytics dashboard aggregates all rate records by trade and job classification. For each trade, the system identifies the earliest and most recent rate records and computes the following:

Total Growth %

((Latest Rate − Earliest Rate) / Earliest Rate) × 100

Represents cumulative wage inflation from the first recorded rate to today.

Average Annual Growth %

Total Growth % / Number of Years

A simple linear annualization — useful as a baseline escalation assumption for budgeting.

Year-over-Year Change

((Rate Year N − Rate Year N−1) / Rate Year N−1) × 100

Shows the specific jump for each individual year. A spike year (e.g., post-pandemic CBA renegotiations) is immediately visible.

Interpreting the Benefit Package Breakdown

The Analytics page surfaces not just base wage trends but the full benefit stack — because total package cost is what actually hits your budget. In NYC construction, benefits often represent 40–60% of the total employer cost per hour.

What to look for in the breakdown:

Pension vs. Annuity split — Some locals have shifted contributions from defined-benefit pension toward annuity (defined-contribution) accounts over time. A growing annuity line with a stable or shrinking pension line signals this structural shift.
Welfare growth rate — Health insurance costs have historically outpaced base wage increases. A trade where welfare contributions are growing faster than base wages will see its total package escalate faster than the headline rate suggests.
Vacation & Holiday fund contributions — In some locals, vacation pay is accrued to a fund rather than paid weekly. This can create cash flow timing differences that affect contractor payment schedules and retainage calculations.

Applying Trend Data to a Pro Forma

The most practical application of wage trend data is building escalation assumptions into a construction pro forma. Here is a structured approach:

Step 1 — Establish your base year cost

Use WageHound's Cost Projection tool to calculate total labor cost at today's rates for your full hours schedule. This is your Year 0 baseline.

Step 2 — Apply trade-specific escalation rates

Use the WageHound Analytics page to pull the 3–5 year average annual growth rate for each trade in your project. Do not apply a single blanket escalation — electricians and laborers often have very different historical trajectories.

Step 3 — Model the escalation by phase

For a 3-year project, apply Year 1 rates to the first 12 months of work, then compound the escalation factor for Years 2 and 3. NYC prevailing wages update July 1 annually, so a project starting in Q1 will encounter its first rate increase mid-execution.

Step 4 — Add a contingency buffer

Historical averages are backward-looking. CBA negotiations can produce unexpected spikes. A 1–2% contingency on top of your modeled escalation is standard practice for long-duration projects.

Data Governance: What WageHound Tracks

WageHound focuses its trend database on Journeyman/Journeyperson classifications for the primary trend series. This is deliberate — Journeyman rates are the most consistently published benchmark across all trades and years, making them the most reliable apples-to-apples comparison over time.

Foreman and General Foreman rates are tracked in the full rate table but are excluded from aggregate trade trend calculations to avoid distortion from classification mix changes between years.

✓ Analytics Use Cases by Role

Owner / Developer: Use 3-year average growth to stress-test the labor line in your Pro Forma.
Estimator: Compare trade-by-trade escalation rates when selecting trade packages for GMP negotiations.
Project Manager: Cross-reference the YoY chart to identify if a CBA spike year falls within your project schedule.
Compliance Officer: Use benefit trend data to verify that fringe contribution rates in certified payrolls reflect the current schedule.
