A bounded scenario, not a cash forecast. Enter operating cash flows only and verify whether financing, taxes, one-time costs, or owner draws belong in your assumptions.
Planning estimate only. Platform fees, taxes, payment costs, and policies can change; verify current terms before pricing.

How this calculator works
Formula
Starting cash is updated month by month by adding modeled revenue and subtracting modeled expenses; each may compound by its entered monthly change. Runway is the first month ending cash reaches zero or below.
Worked example
$10,000 starting cash with $2,000 monthly revenue and $3,000 monthly expenses reaches zero at month 10 when both remain constant.
Assumptions to verify
- Revenue and expenses change at constant monthly rates after month one.
- Financing, taxes, owner draws, and one-time cash flows are excluded unless included in inputs.
- A result beyond the horizon means only that cash stayed positive during the modeled months.
Frequently asked questions
Is this a forecast?
No. It is a bounded scenario using constant assumptions.
What does beyond the horizon mean?
Cash remained above zero during the selected months; it does not mean unlimited runway.
What is operating break-even?
The first modeled month in which revenue is at least expenses before financing and excluded cash flows.
