Frequently Asked Questions

How does the Burn Rate Calculator work?

Enter starting cash, monthly revenue and monthly expenses. The tool computes gross burn (total expenses), net burn (expenses minus revenue) and runway (cash ÷ net burn) locally, then shows break-even timing, funding needs and a 12-month cash projection.

Is the Burn Rate Calculator free to use?

Yes, it is completely free with no hidden fees, subscriptions, or usage limits. No sign-up or account required. With Burn Rate Calculator, re-run with your own inputs before deciding.

How accurate are the results?

Net burn and runway use exact division with monthly granularity and round to 2 decimals. Verify against bank statements and subscription renewals, since mid-cycle hires or annual prepayments shift runway by weeks.

Is my data safe when using Burn Rate Calculator?

Absolutely. All calculations happen locally in your browser. Your data never touches any server and is never stored or tracked. With Burn Rate Calculator, re-run with your own inputs before deciding.

What is burn rate for a startup?

Burn rate is how fast a startup spends its cash each month. Gross burn is total monthly expenses. Net burn is expenses minus monthly revenue. It shows how efficiently a startup manages its money.

What is the difference between gross and net burn rate?

Gross burn is your total monthly spending on all expenses. Net burn is what you actually lose each month after subtracting revenue from expenses. Net burn determines how many months your cash will last.

How is cash runway calculated?

Runway = current cash balance divided by net monthly burn. For example, $500,000 cash with $25,000 net monthly burn gives 20 months of runway. If revenue covers all expenses, net burn is zero and runway is infinite.

What is a healthy burn rate?

A healthy burn rate depends on your stage. Early startups should have 12-18 months of runway. Later-stage startups with revenue should aim to reduce net burn over time and work toward profitability. A burn rate above 50% of cash per year is generally risky.
