A decision-oriented matrix
| Type | Examples | Useful question |
|---|---|---|
| Fixed essential | rent, minimum payment | Can the contract or timing change? |
| Fixed optional | subscriptions, memberships | Is the value used every month? |
| Variable essential | groceries, medicine, transport | What is a safe minimum? |
| Variable optional | entertainment, impulse buys | What limit protects the goal? |
Include infrequent bills
Annual insurance, maintenance, gifts, and seasonal costs are not unexpected merely because they are not monthly. Divide a reasonable annual estimate by 12 for the baseline or maintain a separate cash calendar.
Prioritize changes by total impact
Look for a high amount, low value, and low cancellation cost. Do not begin with spending that protects health, employability, or prevents a larger cost. Renegotiating one recurring contract may improve runway more sustainably than many tiny restrictions.
Test one category at a time
Use category mode in Cash Years and enter realistic averages. Record current runway, then change one category. The difference shows the time value of that decision instead of an abstract savings percentage.
The CFPB spending assessment recommends reviewing several months and accounting for miscellaneous and less frequent expenses. Apply local obligations and protections separately.
