Gym Revenue Loss Calculator
Estimate how much money your gym loses every month to members who renew late, stop coming without telling you, or never clear their dues.
How Much Are You Leaking?
Adjust the sliders below to see how much silent non-renewals and untracked dues could be costing your gym.
You could be losing about ₹22,500 every month (₹2,70,000 a year)
This is an estimate based on the numbers you entered.
How is gym revenue loss calculated?
The calculator multiplies your active members by your average monthly fee, then by the share of members who renew late or churn silently: members × monthly fee × leak %. For example, 150 members paying ₹1,000 with a 15% leak means about ₹22,500 lost every month, or ₹2,70,000 a year.
What leak % should I enter?
Count how many members renewed late, left without telling you, or still owe fees last month, and divide by your active members. If you don't know, start with 15%. Use 5% if you follow up every member on time, and 30–40% if you rarely know who has paid.
How can a gym stop losing revenue to missed renewals?
- Send members an automatic reminder before their plan expires.
- Give every payment an instant invoice so members always know their plan end date.
- Lock app access when a plan lapses and unlock it automatically on renewal.
- Track attendance so you spot members who have stopped coming before they churn.
