How to Use Production Function & Diminishing Returns Calculator

  1. Enter Initial Labor (L1) and New Labor (L2).
  2. Enter Initial Total Output (Q1) and New Total Output (Q2).
  3. Review MPL (ΔQ / ΔL) and Average Product of Labor (APL).

Short-Run Production Stages

Stage 1: Increasing marginal returns. Stage 2: Diminishing positive returns. Stage 3: Negative marginal returns.

Frequently Asked Questions

What is the Law of Diminishing Marginal Returns?
As you add more of a variable factor (e.g. labor) to fixed factors (e.g. machinery), the additional output produced per unit of labor eventually declines.
