About

Marketing directors often struggle to justify the ROI of grassroots programs like "My First Match." However, engaging a fan in childhood creates decades of recurring revenue. This calculator computes the Net Present Value (NPV) of a fan by projecting their spending habits over a lifetime, adjusted for inflation. It allows clubs to quantify the long-term asset value of a single loyal supporter, transforming abstract fandom into concrete financial data essential for strategic planning.

Formulas

The calculation uses the Net Present Value formula to discount future cash flows back to today's value:

LTV = T∑t=1 R_t(1 + i)^t

Where R is annual revenue (Tickets + Merch), i is the inflation/discount rate, and T is years of fandom.

Reference Data

Persona	Annual Ticket Spend	Merch Spend	Typical Duration
Casual Fan	$200	$50	10 years
Avid Supporter	$500	$150	30 years
Ultra / VIP	$1500	$400	45 years

Frequently Asked Questions

Money received in the future is worth less than money today due to inflation and opportunity cost. NPV provides a realistic current valuation of future revenue streams.

This is typically calculated as (Average Life Expectancy - Age at First Interaction). For a child of 10 and life expectancy of 75, this would be 65 years.

This simplified model assumes the "Inflation Rate" input acts as a net discount rate. If ticket prices rise exactly with inflation, the real value remains constant. If prices outpace inflation, you should lower the discount rate slightly to compensate.
