Software change cost worksheet
Calculate a first-year estimate from your own figures. Amounts are illustrative inputs, not published vendor prices.
Enter all fields, using 0 where a cost does not apply. Calculations stay in this browser tab.
What the figures mean
First-year new cash outlay = setup + 12 × new monthly charges + transition overlap. Internal effort = hours × hourly cost. First-year net cash change = new cash outlay − 12 × (retired charges + other avoided cash expenses).
Simple cash payback = (setup + overlap) ÷ positive net monthly cash saving. Training effort is shown separately. If monthly savings do not exceed the new recurring cost, there is no simple cash payback under these inputs. The calculation assumes a full year at the entered run rate and excludes tax, financing, growth and discounting.
Time released does not automatically become cash saved. Include only cash expenses that actually stop in the savings inputs, and avoid counting the same saving twice.
