# Free Runway Calculator: How Many Months Until Cash Hits Zero?

> See how many months until cash hits zero from cash in the bank and monthly burn. Optional burn change, a month-by-month table, and the max burn for N months. Free, in your browser.

## Runway calculator

Enter cash in the bank and a monthly burn, or enter revenue and expenses. The example is $48,000 of cash and an $8,000 monthly burn.

When burn does not change, months of runway = cash ÷ monthly net burn. $48,000 ÷ $8,000 = 6 months. Net burn = expenses − revenue when you enter both. A blank burn-change field counts as 0%.

Month k burn = starting burn × (1 + monthly change)^(k − 1). The last partial month is the cash left ÷ the burn in that month. The table stops at 120 months if cash is still above $0.

Reverse mode: with no burn change, max monthly burn = cash ÷ months. With a monthly change rate g over N months, max starting burn = cash × g / ((1 + g)^N − 1).

The math runs in the browser. It does not upload the form and it does not cite anyone else's runway.

## Runway calculator FAQ

### How are months of runway calculated?

When burn does not change, months of runway = cash ÷ monthly net burn. Net burn = expenses − revenue if you enter revenue and expenses.

### What does reverse mode solve for?

The highest starting monthly burn that brings cash to $0 at the end of the number of months you enter. With no burn change, that is cash ÷ months.
