PakistanBig 4 vs Shift, live.

› Adjust the loaded-cost assumption
A salary isn't the real cost. This adds benefits, payroll taxes, PTO, software, recruiting and overhead — typically 25–40% on top of base pay.
In-house salary defaults are indicative market benchmarks, not quotes — type over every figure with your own data. Savings depend on your actual scope; the calculator is a planning tool, not an offer.
