Burn is the sum of what repeats
A company's burn is, overwhelmingly, its recurring costs: payroll and contractors, cloud and infrastructure, software, rent, insurance. One-off purchases come and go, but the recurring base is what sets the pace the bank balance drains. Total it here and divide your cash by it to see how many months that buys.
Mixed billing is handled for you — a yearly contract is spread across the months it covers — so monthly and annual costs sit on the same monthly scale.
How this fits into your recurring money
Runway is the most consequential recurring-money question a business asks, and the answer is set almost entirely by costs that repeat. Trim the recurring base and every dollar of cash stretches further; let it creep and runway quietly shortens, often without anyone noticing which line did it.
That's the work Recurrings does for a business: every recurring charge in one place, the duplicate tools and unused seats surfaced, and each renewal dated — so the levers that actually move burn are visible before the next invoice, not after.
The math
monthly burn = Σ ( cost × times billed per year ) ÷ 12 annual run-rate = monthly burn × 12 runway (months) = cash in the bank ÷ monthly burn
Each cost is normalized to a monthly figure, summed into monthly burn, and annualized for the run-rate. Runway divides your cash by monthly burn — a rough count of how many months you can operate at today's spend, before any new revenue.
This is gross burn (total recurring spend). If you have revenue, your net burn — and real runway — will be better than the figure here.
Common questions
What counts toward burn?
Your recurring operating costs — payroll and contractors, cloud and infrastructure, SaaS, rent, insurance. This is gross burn (total spend); if you have revenue, net burn is this minus what comes in.
How is runway calculated?
Cash in the bank divided by monthly burn — roughly how many months you can operate before the cash runs out at today's spend, ignoring new revenue. It's a planning estimate, not a forecast.
How do I extend runway?
The fastest lever is usually recurring cost: cut unused SaaS, right-size cloud and seats, and renegotiate the big contracts at renewal. Small recurring savings compound into months of runway.
