Personal inflation emergency fund target basics
Your essentials basket can inflate differently from averages. The risk is being under buffered relative to current costs. Modeling your own basket helps you see how a target might shift when essentials move.
Simple example: 2 to 3 percent over 12 months
Round numbers only, for illustration.
| Assumption | Monthly essentials today | Monthly essentials after 12 months | 6 month target today | 6 month target after 12 months |
|---|---|---|---|---|
| 2% | $3,000 | $3,060 | $18,000 | $18,360 |
| 3% | $3,000 | $3,090 | $18,000 | $18,540 |
This is simplified to show the direction; your numbers will differ based on your basket and inputs.
How to estimate your own essentials inflation
Model a personal basket for your essentials. Focus on the big items first—housing, groceries, utilities. Enter your own assumptions; this is not a forecast.
