Score one feature. See the math.
Enter a rough annual lift and cost. We'll compute NPV, FVI, and payback live. Save the scenario to your workspace when you're ready.
$
How much value does this feature create per year? (revenue, saved cost, or both)
$
Rough one-time investment: engineering time + design + rollout.
How many years of lift do you count? 3 is the CFO-friendly default.
70%
Haircut applied to expected lift when computing FVI.
NPV (undiscounted)
$400,000
$450,000 lifetime lift − $50,000 build cost
FVI (confidence-weighted)
6.30
Higher = better. Score >1 means the confidence-adjusted lift beats the cost.
Payback
4 months
How long until annual lift covers the build cost.
