Fast enough for screening. Explicit enough to challenge.
Label assumptions
When a figure is unknown, keep it visible as an allowance and test a downside case instead of hiding uncertainty.
Save the evidence
A calculator result is only as durable as the comps, scope, term sheet, schedule, and documents behind its inputs.
Keep the original assumptions when the real bills arrive.
