Should I make a part in-house or buy it from a supplier?

It depends on volume and fully loaded cost, not sticker price. Make vs Buy Cost compares internal production cost against the supplier quote including your own overhead and tooling, and Make-Buy Breakeven Volume finds the annual quantity where the cheaper option flips. Add Total Landed Cost so freight, duties, and inventory carrying are counted on the buy side before you commit either way.

What is total landed cost and why does it differ from the quoted price?

Total landed cost is the delivered, all-in cost of a part, not just the supplier's unit price. Total Landed Cost adds freight, duties and tariffs, insurance, handling, and inventory carrying to the quote, which often erases the apparent savings of a low-cost distant supplier. Nearshore vs Domestic Cost applies the same logic to compare a nearby source against an offshore one on true cost.

How do I decide whether to nearshore or reshore production?

Compare full delivered cost and risk, not labor rate alone. Nearshore vs Domestic Cost and Regional Production Savings weigh labor, freight, and duty differences, while Plant Location Cost and Production Footprint Comparison evaluate where a site should sit. Layer in Network Resilience Score and Manufacturing Footprint Carbon Cost so lead-time exposure and emissions are part of the decision, not just the per-unit price.

How do I quantify the risk of outsourcing a critical part?

Score the exposure rather than assuming the supplier holds. Outsource Quality Risk estimates the cost of defects and returns from an external source, Supplier Capacity Risk flags whether the supplier can meet your peak demand, and Supplier Switching Cost captures what changing sources later would cost. Network Resilience Score rolls single-source and geographic exposure into one number so you can see concentration risk across the network.

When does bringing outsourced work back in-house pay off?

Insourcing pays off when volume, control, or risk reduction justify the capital. Insourcing Payback compares the equipment and ramp investment against the per-unit savings versus the supplier to find the payback period, and Make-Buy Breakeven Volume confirms your volume sits above the crossover point. Capacity Outsourcing Gap checks that you actually have or can add the internal capacity before you move the work back.

How do I compare single-site versus multi-site production networks?

Weigh cost against resilience and inventory. Dual-Site Production Cost and Production Footprint Comparison show the added overhead of running multiple plants against a single large one, while Network Inventory Impact captures how footprint choices change safety stock and working capital. Footprint Optimization Score and Network Resilience Score then rank configurations on combined cost, service, and risk so the trade-off is explicit.

Best calculators in this category

Make vs Buy Cost: Compute the fully loaded internal cost of making a part so it can be weighed against the buy quote.
Outsourcing ROI: Estimate outsourcing roi for make-buy, outsourcing and network design using production-ready inputs so teams can screen a capital project before a detailed business case.
Supplier Network Cost: Estimate the annual cost of managing a multi-supplier sourcing network beyond the price of the parts themselves.
Production Footprint Comparison: Compare the annual operating cost of a multi-site production footprint including the cost of changing it.
Total Landed Cost: Roll up the true delivered cost of goods including freight, duty, and clearance, not just the supplier price.
Nearshore vs Domestic Cost: Estimate the cost of shifting sourced volume to a nearshore supplier versus keeping it domestic.
Insourcing Payback: Estimate insourcing payback for make-buy, outsourcing and network design using production-ready inputs so teams can screen a capital project before a detailed business case.
Contract Manufacturing Comparison: Estimates the annual landed cost of routing a program to a contract manufacturer including piece price, the realistic share of volume shifted, and one-time transfer fees.
Capacity Outsourcing Risk Score: Estimate capacity outsourcing gap for make-buy, outsourcing and network design using production-ready inputs so teams can rank risks and decide which issue needs containment, controls, or escalation first.
Supplier Switching Cost: Estimates the one-time cost of moving parts to a new supplier including per-part requalification, the share needing full approval, and bridge inventory during cutover.
Dual-Site Production Cost: Estimates the annual cost penalty of running the same product across two plants from lost scale economies and duplicated tooling and overhead.
Network Resilience Score: Estimate network resilience for make-buy, outsourcing and network design using production-ready inputs so teams can rank risks and decide which issue needs containment, controls, or escalation first.
