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.
What it costs to run and maintain this every year, after it ships.
How many years of lift do you count? 3 is the CFO-friendly default.
Haircut applied to expected lift when computing FVI.
Net benefit, before discounting
$400,000
$450,000 total benefit minus $50,000 build cost
NPV at 10%
$323,028
Future money is worth less than money today, so this is the number a CFO will ask for.
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.
