How Threshold-Triggered COLA Calculator Works?

The Threshold-Triggered COLA Calculator adds up inflation across periods. It pays a cost-of-living adjustment when that total reaches the trigger.

  1. Enter pay

    Type the salary or benefit in force before the trigger rule starts.

  2. Set the trigger

    Type the cumulative inflation that fires an adjustment.

  3. Enter inflation

    Type inflation for each period. The calculator keeps a running total.

  4. Read the schedule

    The output shows when the trigger fires, the COLA paid and pay after each period.

Threshold-Triggered COLA Calculator Formula

The Threshold-Triggered COLA formula pays accumulated inflation once the accumulated amount reaches the trigger.

Accumulated inflation

At = Πsince last COLA (1 + πk) − 1

Trigger rule

COLAt = At if At ≥ Trigger, else 0

Variables

At
Inflation accumulated since the last COLA
Trigger
Threshold that fires an adjustment

Worked example

With a 3% trigger, inflation of 1.8% and 2.4% accumulates to 4.24% in year 2, so a 4.24% COLA is paid in year 2 and the counter resets.

What is Threshold-Triggered COLA Calculator?

The Threshold-Triggered COLA Calculator is a tool that adjusts pay only after cumulative inflation since the last adjustment crosses a set trigger, such as 3%. Once triggered, the COLA pays the full accumulated inflation and the counter resets.

Trigger rules reduce the number of small adjustments and keep catch-ups tied to measured inflation.

What are the uses of Threshold-Triggered COLA Calculator?

There are 4 main uses of the Threshold-Triggered COLA Calculator.

  • Model trigger clauses

    Apply trigger rules from contracts and pension plans.

  • Compare trigger levels

    Compare 2%, 3% and 5% triggers.

  • Forecast adjustment timing

    Predict the year the next COLA fires.

  • Reduce admin work

    Payers test fewer, larger adjustments.
