Batch Size Optimization Calculator
Calculate optimal manufacturing batch size using the EOQ formula. Balance setup costs against inventory holding costs for efficiency.
Free Scheduling Calculators
12 toolsMPS, MRP, shift planning, and changeover time calculators. Browse our free scheduling tools below — no sign-up required.
Changeover Time Calculator
Calculate total changeover time including teardown, cleanup, setup, and first-article inspection. Minimize lost production between runs.
Drum-Buffer-Rope Calculator
Calculate DBR parameters: drum rate from the constraint, buffer time before the constraint, and rope release rate. Apply TOC scheduling.
Master Production Schedule Calculator
Calculate MPS planned production by combining forecast, customer orders, inventory, and scheduled receipts. Drive material and capacity plans.
MRP Calculator
Calculate net material requirements using the MRP formula: gross requirements minus on-hand and receipts plus safety stock, offset by lead time.
Overtime Cost Calculator
Calculate overtime production costs with configurable multipliers. Compare standard vs. overtime cost per unit for manufacturing labor budget planning.
Production Run Length Calculator
Calculate production run length from batch quantity, cycle time, and setup time. Plan scheduling windows and resource allocation.
Production Schedule Calculator
Calculate production schedule by assigning jobs to available time slots based on run length and capacity. Plan daily and weekly output.
Second Shift Cost Calculator
Estimate the total cost of running a second shift including base labor, shift premium, overhead, and supervision for manufacturing planning.
Shift Planning Calculator
Compare production output across 1, 2, and 3 shift patterns. Calculate output per shift factoring in hours, efficiency, and production rate.
Third Shift Cost Calculator
Calculate the full cost of running a third (night) shift including base labor, night premium, overhead, and reduced efficiency for capacity decisions.
Weekend Production Cost Calculator
Calculate the true cost of weekend manufacturing runs including premium pay, overtime multipliers, utilities, and reduced staffing efficiency.
