About

NLE Calc

This utility calculates the Recommended Weight Limit (RWL) and Lifting Index (LI) for single or multiple lifting tasks based on the NIOSH Lifting Equation. It helps assess physical stress to prevent low back musculoskeletal disorders.

Highlights
  • Calculates Recommended Weight Limit (RWL)
  • Calculates Lifting Index (LI)
  • Calculates Composite Lifting Index (CLI)
  • Based on Revised NIOSH Lifting Equation
  • Assesses physical stress for lifting tasks
Features
Read full description

The NIOSH Lifting Equation calculator (NLE Calc) is based on the Applications Manual for the Revised NIOSH Lifting Equation (Pub No. 94-110) and can be used to calculate the Recommended Weight Limit (RWL) and for single or multiple lifting tasks. The Lifting Index (LI) is an index of the relative physical stress for performing a single lifting task and the Composite Lifting Index (CLI) is an index of the overall physical stress for performing multiple lifting tasks. NIOSH recommends an LI and a CLI of 1 or less for protecting workers from physical stress related to development of low back musculoskeletal disorders. Please refer to the Applications Manual for the Revised NIOSH Lifting Equation publication for examples and details on how calculations are performed and what the results imply.

ReceptionRating · Positive reviews · Number of ratings

NLE Calc holds the better App Store score, 2.8 against 2.0. Both are backed by a comparable volume of ratings — 10 and 12 respectively. Written reviews complicate that: 0% of NLE Calc's written reviews are positive against 27% of Inclinometer's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

NLE Calc ships an update fortnightly, Inclinometer every 2 weeks. The most recent releases landed on November 3, 2026 and November 4, 2026 respectively.
