Build, Buy & Migration Calculators

The decisions that get made once and paid for repeatedly: writing software instead of buying it, moving a workload between platforms, and carrying technical debt whose interest is paid in engineering hours.

Which one do you need?

Build vs Buy Software Calculator
Compare building software in-house, including maintenance that never stops, against licensing it, with present values, a break-even year and overrun cost.
Cloud Migration Payback Calculator
Compare on-premises and cloud run rates, add the one-off migration cost, and get the payback period, five-year net position and discounted NPV of the move.
Technical Debt Interest Calculator
Price the drag technical debt puts on delivery each year, compare it with the cost of paying it down, and get the payback period, NPV and cost of waiting.
Fully Loaded Engineering Hour Calculator
Turn an engineer's salary into the true hourly cost a build-versus-buy case needs: benefits, overhead, and only the hours actually available for project work.
