MTBF, MTTR, preventive maintenance, and TPM calculators. Browse our free maintenance tools below — all calculators are instant, accurate, and require no sign-up.
Condition Monitoring ROI Calculator — Calculate the ROI of condition monitoring programs. Compare prevented failure costs against monitoring system investment and operating expenses.
Maintenance Backlog Calculator — Calculate maintenance backlog in weeks by dividing pending work hours by available maintenance capacity. Track and reduce your backlog for reliability.
Maintenance Cost per Unit Calculator — Calculate maintenance cost per unit produced by dividing total maintenance expenditure by production volume. Benchmark your maintenance cost efficiency.
Maintenance ROI Calculator — Calculate the return on investment for your preventive maintenance program. Compare avoided downtime costs against PM program expenses.
Mean Time Between Maintenance Calculator — Calculate MTBM by dividing total operating hours by maintenance events. Track equipment reliability and optimize maintenance intervals.
MTBF Calculator (Maintenance) — Calculate Mean Time Between Failures (MTBF) by dividing total operating time by number of failures. A key reliability metric for maintenance planning.
Planned Downtime Calculator — Calculate total planned downtime from preventive maintenance, changeovers, breaks, and meetings. Optimize your production schedule and reduce losses.
Predictive Maintenance ROI Calculator — Calculate the return on investment for predictive maintenance programs by comparing avoided downtime costs and extended equipment life against investment.
Planned Maintenance Cost Calculator — Calculate the total cost of planned preventive maintenance including labor, parts, and downtime value. Optimize your PM program budget.
Preventive vs Reactive Maintenance Calculator — Compare preventive maintenance costs against reactive maintenance costs. See the financial case for scheduled PM over unplanned emergency repairs.
Preventive Maintenance Cost Calculator — Calculate total preventive maintenance cost including labor, parts, and consumables. Budget PM programs and compare against breakdown repair costs.
Spare Parts Inventory Calculator — Calculate optimal spare parts inventory levels based on failure rate, lead time, and part criticality. Minimize stockouts without overstocking maintenance spares.
Spare Parts Inventory Cost Calculator — Calculate the true cost of spare parts inventory including carrying costs, obsolescence risk, and stockout penalties. Optimize MRO inventory levels.
TPM Score Calculator — Calculate your Total Productive Maintenance (TPM) score as a weighted average of the 8 TPM pillars. Benchmark your maintenance maturity level.
Total Productive Maintenance (TPM) Calculator — Calculate your TPM score from OEE, autonomous maintenance compliance, and PM completion rate. Benchmark your TPM program effectiveness.
Unplanned Downtime Calculator — Calculate unplanned downtime by subtracting planned downtime from total downtime. Quantify unexpected production losses from breakdowns and failures.
Unplanned Downtime Cost Calculator — Calculate the true cost of unplanned downtime including lost production, emergency repairs, expedited parts, and overtime. Justify reliability programs.
