How it works
What this estimate calculates
This TrueCost planning model multiplies monthly essential expenses by the number of months you select. Current eligible savings are subtracted to show the remaining gap, and the gap is divided by the planned monthly contribution to estimate time needed without assuming interest.
Assumptions to keep in mind
- Essential expenses remain constant throughout the selected coverage period.
- Only cash that is available for emergencies is counted as current emergency savings.
- The savings timeline excludes interest, withdrawals, taxes, and changes to monthly contributions.

Questions people ask
How many months of expenses should I choose?
There is no universal amount. Consider income stability, household size, insurance coverage, health needs, and how quickly you could reduce expenses or replace income.
Which expenses are essential?
Include costs you would still need to pay during an income interruption, such as housing, basic food, utilities, insurance, transportation, healthcare, and minimum debt payments.
Should investments count as emergency savings?
Count funds based on how quickly and reliably you could access them without an unwanted sale, penalty, or tax consequence. Long-term investments may not serve the same role as liquid cash.
Use the result as a starting point
Try a conservative scenario and an optimistic one. If the decision only works under one narrow set of assumptions, that is useful information. For a purchase, loan, tax, or investment decision, confirm the final figures with current documents and an appropriately qualified professional.
