What should I budget for uptime monitoring?

Most founders budget nothing for uptime monitoring until their site goes down at 2 AM and they find out about it from a customer.

That is an expensive way to learn. Gartner research from 2014 put the average cost of IT downtime at $5,600 per minute, a figure that has only grown as businesses run more revenue through their digital products. For a SaaS company or e-commerce store, even 30 minutes of undetected downtime can wipe out a week's worth of margin.

The good news: meaningful monitoring does not cost much. Here is what the market actually looks like, and how to decide what you need.

Monitoring costs fall into four rough buckets depending on how much coverage you need.

The biggest price jumps come from check frequency and alert routing. Checking your site every 5 minutes means you might not know it is down for nearly 5 minutes. Checking every 30 seconds means you know within half a minute. For a business processing $10,000/hour in orders, that difference matters more than the $60/month price gap between tiers.

Western DevOps agencies that manage monitoring as part of a retainer typically charge $2,000–$5,000/month. That covers more than just uptime checks — you get a team handling incident response, alerting configuration, and infrastructure maintenance. It is worth it for companies with complex infrastructure and no internal ops capacity. For most early-stage startups, a $40/month tool and a reasonable alert setup gets you 80% of the same protection.

Free monitoring is genuinely good enough for pre-launch and early traction stages. Tools like UptimeRobot and Freshping offer free tiers that check your site every 5 minutes and send email alerts. If you are processing fewer than 100 transactions a day and have not yet found product-market fit, starting here makes sense.

The limits show up fast once you start taking revenue seriously.

Free tiers typically check from a single location. If your monitoring server goes down, you might get false alerts, or worse, no alerts at all when the real outage happens. Paid tiers check from multiple data centers in different regions simultaneously. If three locations all report your site is down, you can be confident it actually is.

SMS and phone call alerts are almost always paid features. Email alerts are fine for a solo founder who checks their phone constantly. A team with rotating on-call responsibilities needs phone calls for 3 AM outages, or someone sleeps through it.

BetterUptime, StatusCake, and Pingdom all offer solid paid tiers in the $20–$80/month range. Datadog and New Relic cover monitoring as part of broader infrastructure observability suites, more powerful, but pricing starts around $15/host/month and scales with usage. For a startup running 3–5 servers, Datadog's infrastructure monitoring runs roughly $45–$75/month before add-ons.

This is the number that should drive your monitoring budget, not the tool pricing.

Downtime has two direct costs: lost revenue during the outage and the customer trust eroded by it. The revenue math is straightforward. If your app generates $50,000/month, that is roughly $70/hour. A 3-hour outage costs you about $210 in direct revenue. Not catastrophic on its own.

The trust cost is harder to quantify but larger. A 2022 study by Ombud found that 88% of users are less likely to return to a site after a bad experience, and an outage is one of the worst experiences a user can have, particularly if they were mid-transaction.

For B2B SaaS companies, downtime triggers SLA credits. A contract promising 99.9% uptime allows for 8.7 hours of downtime per year. If you blow past that, you owe customers credits, often 10–25% of their monthly fee for each additional hour of downtime. At $5,000 ARR per customer, with 50 customers, one bad incident outside your SLA window can cost $12,500–$31,000 in credits before you count churn.

The useful formula: divide your monthly revenue by 720 (hours in a month). That is your hourly revenue. Any monitoring plan that costs less than one hour of revenue per month is a reasonable investment, assuming it would have caught the last outage before your customers did.

A monitoring setup that actually protects a revenue-generating business covers four things.

Uptime checks confirm your site or API responds correctly, not just that a server is running. A server can be online while your app returns errors on every request. Uptime checks should hit a real URL and verify the response, ideally a page that requires your database to respond, not just a static file.

Alert routing gets the right person notified through the right channel. Email for low-urgency issues during business hours. SMS or phone call for anything that goes down during peak hours or overnight. Most paid tools include integrations with Slack, PagerDuty, and Opsgenie so alerts land where your team already works.

A public status page is worth more than most founders realize. When your service is down, your first 50 support tickets will all be "is your site down?" A status page you update in real time cuts that volume dramatically and signals professionalism to customers. BetterUptime and Statuspage.io both offer hosted status pages starting around $10–$30/month as add-ons.

Response time monitoring catches degradation before it becomes an outage. A page that loads in 8 seconds is not "down," but it is losing you customers. Studies by Google found that pages loading in under 3 seconds see 32% lower bounce rates than those taking 5 seconds. Response time alerts let you investigate slow performance before users abandon the flow entirely.

A complete setup covering all four typically costs $50–$100/month for a startup with 5–10 services to monitor.

Four signals tell you the free or starter tier is no longer enough.

Revenue dependency is the most straightforward. Once your monthly revenue exceeds roughly $5,000, the cost of a 2-hour undetected outage, in both direct revenue and customer goodwill, exceeds the annual cost of a $50/month monitoring plan. The math stops being a debate.

Team size changes what alert delivery you actually need. Solo founders can get away with email alerts. Once you have two or more people sharing on-call responsibilities, you need a plan that supports multiple alert contacts and escalation policies. Most starter tiers cap you at one or two alert recipients.

Check frequency is where the numbers get concrete. Five-minute check intervals mean your average detection time for an outage is 2.5 minutes. At 1-minute intervals, it drops to 30 seconds. For a checkout flow processing $200 in transactions per minute, the $20/month gap between a 5-minute and 1-minute plan pays for itself in the first incident.

SLA commitments make monitoring mandatory. If you have signed contracts with uptime guarantees, you are legally obligated to detect and respond to outages quickly. Monitoring is no longer optional infrastructure, it is risk management. A professional tier plan with documented incident response history also helps in due diligence conversations if you raise a round.

Starting on a free plan is sensible. Staying on a free plan past $10,000 MRR is a false economy.
