Definition

Cumulative means increasing by adding one part to another over time.

Cumulative describes something that builds up gradually as more is added. Each new amount is combined with what came before, creating a total. It is often used for totals, effects, or results measured over a period of time.

Examples

  • The cumulative effect of stress can harm your health.
  • We tracked the cumulative sales for the entire year.
  • After three hours, the cumulative delay reached forty minutes.

Common mistake

Learners sometimes use cumulative for a single, one-time change instead of something that builds up over time.
