Trampoline Park ROI Calculator: Return on an Indoor Park
Work out the return on a trampoline park — both the total ROI and the annualized rate — from what you invested to build it and the net profit plus equipment resale it returned over the years you ran it.

How This Calculator Works
Enter your total startup investment (trampolines and attractions, build-out, lease, safety systems, POS), the total returned (net profit over the period plus any equipment resale), and the number of years. The calculator returns total ROI, the annualized rate, and net profit.
The Formula
Return on Investment
V_start = amount invested, V_end = amount returned; annualized ROI = (V_end / V_start)^(1/n) − 1
Worked Example
Invest $200,000, take out $360,000 of net profit over 5 years, and that's an 80% total ROI — about 12.5% a year annualized. Trampoline parks earn from admissions (often time-based jump passes), birthday parties and group events, and concessions. But they're capital-intensive (a large leased space full of attractions), carry high fixed costs (rent, substantial staffing for safety, and notably high liability insurance), and face equipment wear and a novelty curve — so the headline ROI must absorb significant ongoing costs.
Key Insight
Trampoline parks are a high-capital, high-fixed-cost experience business with a specific risk profile that shapes the return. Revenue leans on admissions plus the high-margin extras that drive the model — birthday parties, group/corporate events, and concessions — so parks compete hard for party bookings and memberships to fill weekday and off-peak capacity. The cost structure is demanding: rent for a large warehouse-style space, heavy staffing (safety monitors are essential), and liability insurance that is among the highest for any leisure business given the injury risk — a non-negotiable, significant line item. Equipment wears out (trampolines, padding, and attractions need regular replacement for safety and appeal), and the novelty factor means parks must refresh attractions to sustain repeat visits. As with other experience businesses, annualize the multi-year return to judge it fairly, and make sure the net profit you enter has already subtracted rent, staff, insurance, and maintenance — gross admissions look impressive but the fixed costs take a heavy cut. Location, party/event sales, membership programs, and rigorous safety/insurance management separate a profitable park from a money-loser.
Frequently Asked Questions
How is trampoline park ROI calculated?
Net profit (returned minus invested) divided by the amount invested, times 100. $200,000 in and $360,000 out is an 80% total ROI; over 5 years that's about 12.5% annualized.
How does a trampoline park make money?
From admissions (often time-based jump passes), birthday parties and group/corporate events, memberships, and concessions. The high-margin extras — especially parties and food — drive profitability, which is why parks compete hard for event bookings and work to fill off-peak capacity.
Why is insurance such a big factor?
Because the injury risk is significant, trampoline park liability insurance is among the highest for any leisure business — a major, non-negotiable fixed cost. Rigorous safety systems and trained monitors both protect guests and help keep insurance manageable. It's central to the cost structure.
What should 'total returned' include?
Net profit over the whole period — admissions, party, and concession revenue after rent, staff, insurance, and maintenance — plus any resale value of equipment. Using gross revenue overstates the return; the large space, heavy staffing, and insurance take a substantial cut.
Why annualize the return?
Because total ROI ignores time. An 80% return over 5 years is only about 12.5% a year. Annualizing puts the park on equal footing with other investments and businesses, the fair way to judge whether the large build-out investment paid off given the effort and risk.

Methodology & Review
ROI is net profit as a percent of the amount invested; annualized ROI converts the total return to a yearly compound rate. The amount returned should be net profit over the period (admissions and concession revenue after rent, staff, insurance, and maintenance) plus any resale of equipment.
