Frequently Asked Questions

How is cost of living increase calculated?

The cost of living increase is based on the Consumer Price Index (CPI). To calculate it, take the CPI from the current year minus the CPI from the previous year, divide by the previous year's CPI, and multiply by 100. For example, if CPI went from 300 to 309, the cost of living increase is (309-300)/300 × 100 = 3%.

What is a typical cost of living raise in 2026?

The estimated 2026 Social Security COLA is approximately 2.8%. Private-sector cost of living adjustments typically range from 2-4% depending on industry and region. In high-inflation years, it can exceed 5-8%.

Should my raise match inflation exactly?

A raise that only matches inflation means your purchasing power stays flat — you're not getting ahead, just not falling behind. To build real wealth, your raise should exceed inflation by 2-3% or more. If your employer offers only a COLA match, consider negotiating for additional performance-based increases.

How much purchasing power do I lose if I don't get a raise?

At 3% annual inflation, a salary that stays flat loses about 26% of its purchasing power over 10 years. At 4% inflation, the loss is about 34% over 10 years. This is why regular cost of living adjustments are critical — even small gaps compound significantly over time.

What's the difference between a COLA and a merit raise?

A COLA (cost of living adjustment) is an across-the-board increase designed to maintain purchasing power — everyone gets the same percentage. A merit raise is performance-based and rewards individual contributions. Ideally, you should receive both: a COLA to keep up with inflation, plus a merit raise for your performance.

How do I ask for a cost of living adjustment?

Use CPI data from the Bureau of Labor Statistics or Statistics Canada to show the exact inflation rate. Frame the ask as maintaining your real compensation, not as a favor. Say something like: "With inflation at 3.5% this year, my current salary represents a real-terms pay cut. I'd like to discuss a cost of living adjustment to keep my compensation at its current purchasing power level."
