Maintenance Calculator.com
Maintenance cost and interval calculator bridging the gap between free spreadsheets and full CMMS platforms.
Manufacturing MaintenanceFrom $199/mo

Overview
Register your equipment fleet, calculate optimal PM intervals, and project annual maintenance cost across all assets — a persistent, multi-user calculation engine for the planner who needs 'what should my intervals be and what will this cost next year?' not a full work-order CMMS.
The problem
Managers calculate intervals and budgets from OEM manuals, tribal knowledge, and Excel — producing inconsistent schedules, surprise repairs, and costly reactive cycles. Free calculators have no asset registry; full CMMS tools are overbuilt and overpriced.
Key features
- Asset registry (category, location, purchase date, replacement value, OEM interval)
- Automated PM due-date calculation (days/hours/cycles) with override
- Status indicators (on-track / due-soon / overdue)
- PM history log with technician and notes
- Per-asset annual maintenance cost estimate (labor + parts)
- Fleet-level cost rollup by site and category
- Cost-as-%-of-asset-value vs. industry benchmark
- PM schedule calendar and compliance summary report
Benefits & outcomes
- Project next year's maintenance cost across the whole fleet
- Replace the interval-and-budget spreadsheet
- Prevent premature asset replacement
- Build an OSHA/CSA-ready compliance trail
