A luminous calendar ribbon connects available cash to future operating milestones.

What you will learn

  • Calculate a simple cash-runway estimate
  • Build a calendar with decision checkpoints
  • Separate forecast assumptions from available cash

Cash runway estimates how long your available operating cash can support the business at its current net cash burn. Use it to work backward from a cash constraint, not to predict when an investor will say yes. A useful fundraising timeline connects preparation, conversations, and fallback decisions to the same cash forecast.

Calculate the starting point

For a business spending more cash than it collects, divide available operating cash by monthly net cash burn. Use bank cash that is actually available to operate. Keep restricted funds and hoped-for investment separate. A profitable or unevenly collecting business needs a monthly cash forecast rather than a misleading negative or infinite runway number.

Simple runway = available operating cash ÷ monthly net cash burn
Net cash burn = operating cash paid out − operating cash collected

Worked example: one company, three scenarios

Illustrative startup: $360,000 of available cash, $70,000 of monthly operating payments, and $25,000 of collections. Net burn is $45,000, giving eight months at that unchanged rate. This excludes new financing and assumes no major one-off payment.

ScenarioMonthly net burnSimple runway
Base: $70K paid, $25K collected$45,0008 months
Slower collections: $70K paid, $15K collected$55,000About 6.5 months
Planned hire: $80K paid, $25K collected$55,000About 6.5 months

The two downside cases have the same simple result but different causes. A late customer payment may recover later; a hire can create an ongoing commitment. Put those cash movements into specific months before deciding how much time you have.

Build a backward calendar

CheckpointDecisionOwner and evidence
This weekReconcile cash, obligations, and collectionsFinance owner; bank and contract records
Preparation checkpointApprove the story, model, and materialsFounder; dated assumptions and ready documents
Conversation checkpointAssess actual investor next stepsFounder; meeting notes, not deck views
Fallback checkpointDecide which spending or funding alternatives to investigateLeadership; downside cash forecast

Choose your own checkpoint dates from the downside forecast and the work required. Do not treat the cash-exhaustion date as the date to begin looking for alternatives. Leave room for decisions, implementation, and delayed collections. No standard fundraising duration fits every company.

Your runway worksheet

As of: [date]
Available operating cash: [amount + source]
Next three months of payments: [by month]
Expected collections: [contract timing + confidence]
Large one-off obligations: [amount + date]
Base / downside minimum cash: [amount + date]
Next fundraising review: [date]
Fallback decision checkpoint: [date + owner]

Update the worksheet when cash assumptions change, not only when an investor meeting happens. Compare actual collections and payments with the prior forecast so the timeline remains an operating tool.
