Choose the calculator that matches the decision you are making, then enter current, documented assumptions rather than optimistic targets. Save the inputs with the result so another person can reproduce the estimate. Compare a conservative, expected, and ambitious scenario, and check which assumptions change the answer most. These tools provide directional estimates, not legal, tax, investment, or accounting advice. Validate material decisions with the appropriate specialist and with your own operational data. Revisit the calculation after implementation to compare the forecast with actual cost, time saved, revenue, or conversion performance.
