You do not need an account, and nothing is stored beyond the check itself. Read every result as a nudge, not a verdict: a single amber item will not sink a site, but a pattern of reds usually explains why visitors leave or Google holds you back. When you are ready to fix something, each finding links to a plain-language guide.
Every Downtime Cost Calculator plan includes Instant result cards, Plain-language fix notes, No signup required, Privacy-first processing as standard — provisioned by our India-based team, billed in INR with GST invoicing.
Downtime Cost Calculator — What You Get
The formula is deliberately transparent so you can audit it. Direct downtime cost = revenue per hour × hours down, where revenue per hour comes from your own numbers — monthly online revenue ÷ operating hours, or booked leads × conversion value for service businesses. Layer on the multipliers the calculator applies: wasted ad spend during the outage (budget burning on an error page), recovery labour, and the trust cost that shows up as reduced conversion for days after.
- eCommerce — peak-hour sensitivity multiplies the hourly figure sharply.
- Lead-gen — a missed form fill during business hours is a lost opportunity, not a delayed one.
- SLA math — the uptime percentage translates to real hours (below).
Run your numbers, then compare infrastructure on network status — the measured-uptime history is published there, and backup insurance on server backup solutions.
Who is this for?
Uptime percentages translated into real time, because the decimals hide hours: 99.9% ('three nines') = 8.76 hours down per year, or about 43.8 minutes per month; 99.5% = 43.8 hours a year; 99.95% = 4.38 hours a year. Read the SLA line against the formula and the honesty emerges: a store doing ₹1,00,000/month online loses roughly ₹138/hour at 99.9% uptime — before the ad waste and the post-outage conversion dip.
The conversion-rate impact deserves its own line: visitors who hit an error page once arrive pre-sceptical next time, which the calculator's trust multiplier estimates rather than pretends to know exactly. Choose the uptime target by revenue class, then verify the host publishes measured numbers — marketing decimals and measured hours are different documents.
