- Expense
- 15000 USD
- Income
- 5000 USD
- Buffer
- 10 %
Example result: 10.8 months
The example is fixed while your live result above changes. Differences in display rounding do not change the underlying calculation.
How to use
Start with the most uncertain input
Compare three scenarios
Compare conservative, baseline, and optimistic cases instead of treating one result as a forecast.
Save and verify
Save the assumptions and update them when measured data becomes available.
About this calculation
How is this calculated?
Months = cash × (1 − buffer%) ÷ (monthly expenses − emergency income), when the spending gap is positive.
What does this estimate exclude?
When income covers expenses, the model shows that reserves are not needed for the entered recurring gap. One-off expenses and changing income are not forecast.
