Software Development Partner TCO Calculator
Build a transparent project-cost scenario for an external software engineering partner, including delivery labor, rework allowance, management overhead and tooling.
Results
Engineering method
This is a budgeting model, not a vendor-price estimate. Direct labor is hours × rate. Rework is modeled as a percentage of direct labor. Management overhead is applied to direct labor plus rework, then tooling is added over the project duration.
TCO = direct labor + rework allowance + management overhead + project tooling.
