How do I enter a cash flow that has a cost-of-living adjustment (COLA)?

Last published on: September 03, 2025

Income Lab allows you to enter cash flows with the following three inflation treatments:

  1. Adjusted for inflation: cash flows that are adjusted over time to account for inflation. These are sometimes called "real" cash flows.
  2. Not adjusted for inflation: cash flows that remain at the same dollar amount over time, with no adjustments. These are sometimes called "nominal" cash flows.
  3. Custom: cash flows that are adjusted annually by a fixed percentage.

If you have a cash flow with a cost-of-living adjustment (COLA), choose the third option. When you do so, a new field called Custom % will appear in the details of this cash flow. Simply fill in the annual percentage COLA rate and you're all set!

When you're entering a cash flow with a COLA, please use the following rules for filling in the amount and begin monthbegin year fields.

Cash Flow Beginning Point is...   Amount  Begin Year / Begin Month
 In the Future  Anticipated first amount  Date of first anticipated receipt
 In the Past  Last amount received  Date of last payment received


NOTE: Income Lab assumes that all COLAs take effect in January.
