What this tool does
Set a planning target by multiplying monthly essential expenses by a chosen number of months, then estimate the remaining gap and saving time.
How to use it
- Enter essential monthly expenses rather than all discretionary spending.
- Choose how many months you want the fund to cover and enter savings already reserved.
- Add a planned monthly contribution to estimate the number of whole months to the target.
Formula and method
Target = essential monthly expenses × months of coverage. Gap = max(target − current savings, 0). If a contribution is entered, months to goal = gap divided by the monthly contribution, rounded up.
Worked example
Essential expenses of 2,500 for six months create a 15,000 target. With 5,000 saved, the gap is 10,000; contributing 500 per month takes 20 months without interest.
Common uses
- Setting a first emergency-savings milestone
- Testing different coverage periods
- Turning a savings gap into a monthly plan
Limitations
The chosen coverage period is a planning assumption, not a universal recommendation. The estimate ignores interest, inflation, taxes and withdrawals and does not assess job stability, insurance, dependants or access to credit.
FAQ
What counts as essential expenses?
Include costs you would still need during an income interruption, such as housing, basic food, utilities, insurance, transport and minimum debt payments.
Does the time estimate include investment growth?
No. It divides the current gap by the contribution and deliberately assumes no interest or market return.
