AI App MaintenanceCost Estimator

Calculate your true monthly maintenance cost. Compare DIY vs freelancer vs retainer. See what “no maintenance” actually costs you.

How to Estimate Your AI App's Monthly Maintenance Cost

  1. 1Describe your app — estimate your monthly maintenance costs by answering 5 questions about app type (SaaS vs. internal tool vs. e-commerce vs. consumer app), active user count, integration complexity (number of third-party APIs and payment providers), hosting environment (serverless vs. container vs. VPS), and security requirements (compliance needs, PII handling). These five factors determine your baseline maintenance load and cost tier.
  2. 2Select maintenance needs — indicate how often you expect bugs to surface (daily, weekly, rarely), how quickly fixes need to be deployed (same day, within a week, no SLA), and whether you need ongoing feature additions in addition to bug fixes and security patches.
  3. 3Choose your maintenance model — compare the true cost of three options: DIY (your time at an estimated hourly value), freelancer (per-hour rates with typical response times), or a monthly retainer (predictable flat fee). The calculator shows total cost including hidden costs like security incident response.
  4. 4Review your estimate — get a monthly cost range broken down by category (bug fixes, security patches, dependency updates, feature work, emergency response). The estimate includes hidden costs most founders miss: the $2,000–10,000+ cost of a single unpatched security incident and emergency downtime response.
