Personal inflation rate calculator
CPI is one basket. Your future is another. Build a sourced basket, set the weights, and compare the modeled rate with CPI at these assumptions.
Direct answer
A personal inflation rate is the weighted growth rate of the costs that matter to a specific life: housing, food and general CPI, healthcare, transportation, and education. Change the weights and source rows, and the rate changes. It is an educational measurement at these assumptions, not a prediction.
Modeled result
Weighted basket rate, at these assumptions.
General CPI baseline, at these assumptions.
Personal rate minus CPI, at these assumptions.
How to read it
CPI is useful because it gives the whole country a common yardstick. A personal inflation rate asks a narrower question: what happens when the basket is tilted toward the costs that define the future you are trying to afford?
The assumptions in the calculator come from the active source rows below. Change a source or a weight, and the modeled rate changes with it.
Use this result as a planning lens. For the underlying formulas and source discipline, read Methodology. To translate the rate into a target, use the required-return calculator. To see what a single cost may become, use the future-cost calculator. For a quick resource comparison, use the on-track checkup. The calculators hub lists every shipped calculator.

FAQ
A personal inflation rate is a weighted estimate of how fast the costs in a specific basket have grown at these assumptions. It can differ from CPI because the basket may emphasize housing, healthcare, transportation, or education differently.
No. The calculator uses sourced historical rate rows and editable weights to show an educational measurement at these assumptions, not a forecast or recommendation.
The calculator subtracts the CPI row from the weighted basket rate. A positive gap means the modeled basket has grown faster than CPI at these assumptions.
