Wood & Paper Manufacturing calculator

Dryer Energy Cost Calculator

Drying is one of the most energy-hungry steps in wood and paper manufacturing, and the dryer often runs long enough that its electricity bill dwarfs the rest of a line. This calculator converts a dryer's connected load, runtime, and blended electricity rate into total energy cost and, critically, cost per unit dried. Kiln operators, energy managers, and plant controllers use it to benchmark dryer efficiency, price drying into a per-board or per-ream cost, and spot when a schedule change or off-peak run would save money. Because dryer cost is driven by kilowatt-hours consumed, it makes the trade-off between faster cycles and lower energy immediately visible.

What this calculator does

  • Estimate dryer energy cost for wood and paper manufacturing using production-ready inputs so teams can budget energy cost, compare equipment settings, or include electricity in the quote.
  • Use it when dryer energy cost in wood and paper manufacturing is being quoted and energy is a real chunk of the wood and paper manufacturing cost stack.
  • It computes total dryer energy cost by multiplying connected load, runtime, and electricity rate, then divides by units processed to give cost per unit and reports kWh used and hourly cost.

Formula used

  • Total dryer energy cost energy cost = dryer energy cost connected load × dryer energy cost runtime × blended electricity rate
  • Energy cost per unit = total energy cost ÷ units processed during runtime

Inputs explained

  • Dryer energy cost connected load:
  • Dryer energy cost runtime:
  • Blended electricity rate:
  • Units processed during runtime:

How to use the result

  • Use it to price drying into product cost, compare dryer runs, or evaluate off-peak scheduling and load-reduction projects.
  • It assumes the dryer draws its full connected load for the entire runtime, so a dryer that cycles heaters or modulates fans will show a higher figure than it actually consumes.

Current U.S. benchmarks

  • As of Apr 2026, industrial electricity averages 8.7 cents per kWh across the U.S. (EIA), up 5.5% from a year earlier. State averages range widely, so plants should confirm against their own tariff.
  • The producer price index for lumber and wood products stands at 280.994 (BLS, May 2026), up 4.2% from a year earlier. Quotes priced off last quarter's material cost miss this move.
  • The producer price index for paperboard and containers stands at 276.831 (BLS, May 2026), up 8.8% from a year earlier. Quotes priced off last quarter's material cost miss this move.
  • The U.S. has 13,899 wood product manufacturing establishments employing about 432,255 workers (Census County Business Patterns, 2023).

Common questions

  • How do you calculate dryer energy cost? Multiply connected load in kW by runtime in hours by the electricity rate per kWh. A 12 kW dryer running 8 hours at $0.12/kWh uses 96 kWh and costs $11.52 for the run.
  • What is the energy cost per unit here? Dividing the $11.52 run cost by 1,000 units processed gives about $0.0115 per unit. That per-unit number is what you fold into product cost or compare across drying schedules.
  • How much energy does the dryer use? At 12 kW for 8 hours the dryer consumes 96 kWh. Multiplying that by the $0.12 rate is what produces the $11.52 total, and it is the figure to track for demand and efficiency.
  • What is a good dryer energy cost per unit? It depends heavily on product and moisture removal, but the goal is a stable or falling per-unit cost. If cost per unit climbs while the rate holds, either throughput dropped or the dryer is running longer than the load requires.
  • Connected load vs actual draw: does it matter? Yes. This tool uses connected load for the whole runtime, which is a worst-case estimate. If your dryer modulates or cycles, use an average measured kW to avoid overstating cost.
