Overhead Cost Calculator 2025: Fixed, Variable, Allocation — Control Indirect Costs

Overhead eats profit. Our overhead cost calculator totals fixed & variable indirect costs, computes rates, and allocates to products or departments.

In 2025, with remote work and AI, overhead is evolving — but still critical.

Overhead Types

Fixed Overhead

Rent, insurance, admin salaries — don’t change with production.

Variable Overhead

Supplies, utilities, maintenance — vary with activity.

Overhead Rate Formula

Rate = Total Overhead ÷ Allocation Base

Bases: Direct labor hours, machine hours, units produced, direct labor cost.

Why Overhead Matters in 2025

High overhead kills margins. Low overhead wins tenders. Track monthly.

How to Use the Calculator

  1. Enter fixed overhead (rent, insurance)
  2. Input variable overhead (supplies, indirect labor)
  3. Add allocation base (hours, units)
  4. Click “Calculate” — see total, rate, per unit

Reduce Overhead in 2025

  • Remote Work: Cut rent
  • Cloud: Pay-per-use
  • Outsource: Admin, IT
  • AI: Automate billing, HR
  • Zero-Based Budget: Justify every cost

Overhead vs COGS

COGS = direct materials/labor. Overhead = indirect. Use COGS tool.

Overhead Rate Benchmarks

  • Manufacturing: 20–40% of direct costs
  • Retail: 15–25%
  • Services: 30–60%

2025 Trends

  • Hybrid Overhead: Mix fixed/variable
  • Real-Time Tracking: IoT sensors
  • Sustainability: Green overhead
  • AI Prediction: Forecast variable costs

Common Mistakes

  • Under-absorbing overhead
  • Wrong allocation base
  • Mixing fixed/variable
  • Ignoring depreciation
