About
How It Helps
This calculator estimates burn rate and runway so you can understand how long current cash lasts under current operating assumptions.
Core fields are monthly expenses, monthly revenue, and cash balance. These drive net burn and runway duration.
Scenario inputs such as funding changes, growth assumptions, or cost cuts help model how runway shifts over time, not just in a single static month.
Use outputs as planning guidance for hiring pace, vendor commitments, fundraising timing, and break-even tracking.
FAQ
Frequently Asked Questions
What is the difference between gross burn and net burn?
Gross burn is total monthly operating spend. Net burn is gross burn minus monthly revenue.
How is runway calculated?
Runway is estimated as current cash balance divided by net monthly burn, expressed in months.
Can I use this for scenario planning?
Yes. Adjust revenue and expense assumptions to model cases such as hiring, budget cuts, or new funding and compare resulting runway changes.
