Business Resilience Stress Test
A healthy plan should work on a good day. A resilient one should tell you what to do on a bad one. Use this tool to see how changes in revenue, costs, and funding timing affect your runway, then review the operational risks that could disrupt the business even when the spreadsheet still looks fine.
1. Test the numbers
Enter your current monthly figures, then create a downside scenario. The calculator compares your normal runway with the stressed case.
Suggested management trigger
2. Stress-test the real business
Money is only one failure point. Open each scenario and ask whether your business could keep delivering its minimum viable service if it happened tomorrow.
Cash and runway
Revenue is 40% below plan for six months.
Monthly burn, remaining runway, and the date cash reaches zero.
Freeze hiring, cut nonessential software or advertising, renegotiate contracts, and prepare an earlier fundraising process.
Fundraising delay
The next investment round is delayed by nine months.
Whether the company can survive without new equity.
Reduce burn, identify bridge financing, and move fundraising milestones earlier.
Customer concentration
The largest customer, responsible for 25% of revenue, cancels.
Revenue gap and the effect on staffing and supplier commitments.
Diversify the pipeline, limit concentration, use shorter commitments, and cross-sell smaller customers.
Demand collapse
Demand suddenly falls by 70%.
Minimum revenue required to operate and which costs are truly fixed.
Offer a lower-cost product, target adjacent customers, pause expansion, and renegotiate leases or vendor obligations.
Unit economics
Customer-acquisition cost doubles while conversion falls.
Whether a new customer remains profitable and how long payback takes.
Shift toward partnerships, referrals, content, retention initiatives, or lower bidding limits.
Cloud or payment outage
A core cloud provider or payment processor is unavailable for 24–72 hours.
Which services stop, expected recovery time, and lost transactions.
Create backups, status communications, manual payment alternatives, and a tested restore procedure.
Cyberattack
Ransomware or an account takeover blocks access to customer data.
Backup quality, decision authority, notification obligations, and recovery time.
Use MFA, offline or immutable backups, defined incident-response roles, and tabletop exercises.
Supplier disruption
A manufacturer, logistics partner, or key software vendor fails.
Inventory cover, alternate-supplier lead time, and cost impact.
Qualify backup suppliers, carry critical inventory, and reduce single-source dependency.
Key-person loss
A founder or critical team member is unavailable for one month.
Knowledge held by one person and approvals or access that cannot be delegated.
Document processes, store credentials safely, assign deputies, and cross-train staff.
Reputation shock
A viral complaint or product-safety concern causes cancellations.
Response time, refund exposure, and escalation process.
Prepare a response protocol, clear refund policy, spokesperson, and root-cause review.
Regulation or platform change
New rules or a platform algorithm change reduces reach.
Dependence on one platform, compliance cost, and available alternatives.
Build owned channels, audit data practices, and diversify sales channels.
Rapid growth
Demand doubles in 60 days.
Service capacity, inventory, quality control, response time, and working capital.
Set capacity limits, use waitlists, secure backup fulfillment, hire contractors, and protect quality.
Planning tool only. Results depend on the assumptions entered and should be considered alongside the company’s actual cash commitments, debt obligations, tax requirements, financing terms, and operating constraints.
