TL;DR

Burn rate is how fast you're spending money relative to what's coming in. If your expenses exceed your income by $5,000 a month and you have $25,000 in reserve, your burn rate implies 5 months of runway before cash runs out.

Key Points

✓

Gross burn rate = total monthly cash outflows; net burn rate = monthly outflows minus monthly inflows (the cash you're consuming net of revenue)

✓

Runway = cash on hand ÷ net burn rate; this tells you how many months of operation remain at current spending

✓

For freelancers, burn rate matters most during slow periods — knowing your monthly baseline expenses informs how much you need to earn to stay solvent

✓

Reducing burn rate extends runway: cut non-essential subscriptions, defer large purchases, reduce contractor spend during slow periods

Gross vs. Net Burn Rate

Gross burn rate is your total monthly operating expenses — what you spend each month regardless of revenue. Net burn rate is gross burn minus monthly revenue — how much cash you're actually consuming on a net basis¹. If your monthly expenses are $8,000 and you earn $6,000 in a given month, your net burn rate is $2,000. If you have $20,000 in cash reserves, your runway is 10 months at that rate. For most profitable freelancers and small businesses, the concern isn't net burn rate (since revenue exceeds expenses) but rather gross burn rate and Liquidity — how many months of expenses can you cover if revenue stops entirely? That's your true financial resilience.

Burn Rate for Freelancers

Freelancers typically think about burn rate in the context of slow periods or transitions — between clients, during a low-revenue month, or when starting a new business. Knowing your monthly baseline expenses (your gross burn) tells you the minimum you need to earn to stay solvent. If your fixed costs are $3,500/month (rent, subscriptions, insurance, debt service), and variable costs average $1,500, your gross burn is $5,000. To maintain a 6-month runway, you need $30,000 in accessible savings. This number is concrete and motivating — it's the target for your cash reserve. Many freelancers also track burn rate to evaluate whether their current client load is generating enough income to cover burn plus savings goals.

Using Burn Rate to Make Decisions

Burn rate supports several practical decisions: Should you take on a lower-rate client while searching for better work? Compare the revenue against your burn rate — partial coverage is better than nothing. Should you invest in new equipment or training? Calculate the impact on monthly burn and how many months it extends runway. Should you take unpaid time off? Burn rate tells you what it costs in cash. Should you hire a contractor? Add their cost to gross burn and recalculate runway. During periods of strong revenue, reducing gross burn by eliminating unused subscriptions or renegotiating vendor contracts builds the runway cushion that makes lean periods survivable.
