Enter a product's ramp-up, plateau and peak revenue, a market-entry delay, and how much of the peak revenue the delay permanently costs. The tool computes the revenue lost against the no-delay baseline — split into the loss from the late start and the loss from the permanently lower plateau a delayed entrant reaches.

The plateau loss is your own judgement from the field: 0 % means the product still reaches full peak revenue despite arriving late; 10 % means it settles permanently at 90 % of peak.

Weeks are whole numbers. Use a comma or a period for decimals; do not use thousands separators.
