Definition and method

What this calculator answers

The raise size that funds a runway horizon at the current monthly burn — sized against current cash on hand.

Cash needed for the chosen horizon

Cash needed = owner-selected runway months × monthly net burn entered. The horizon is a planning choice, not a standard funding period.

Worked example: your figures

The interactive result above is the worked example. Change any input and the same deterministic engine recomputes the answer; this page does not insert a generic example business or silently treat example values as a benchmark.

Frequently asked questions

What is the funding-need calculator?

Funding need = (monthly burn × months runway needed) − current cash. The dollar figure to bring forward to cover the runway target — what an investor, lender or your own planning lens should size the raise at.

Funding Need

How many months runway should I raise for?

There is no universal numeric benchmark for this decision. The right comparison depends on the industry, geography, business model, time period and exact metric definition. Use the business’s own history, economics and explicit target unless a verified benchmark matching that scope is available.

Funding Need

Should I add a buffer to the raise?

Yes — at least 10–25% buffer for under-writings or missed milestones. A raise that hits the runway target has no slack the moment a milestone slips or a month underperforms.

Funding Need

What about seasonal businesses?

Use the highest observed monthly shortfall over the rolling 12 months as a conservative owner-entered scenario, not as MarginKoala’s prediction. Compare that case with the recorded cash balance and known commitments before choosing a funding amount.
