Subscription ROI Calculator

A subscription ROI (Return on Investment) analysis helps you determine whether a recurring service is providing real value relative to its cost. The key metric is cost-per-use, the amount you actually pay each time you use the service.

The core formula:

Cost Per Use = Monthly Cost ÷ Monthly Usage Frequency

If your cost per use is lower than what you would pay for the equivalent on-demand service, the subscription is worth keeping. If higher, you are overpaying for convenience.

Example analysis:

You pay $15/month for a streaming service.

• If you watch 30 hours/month: $15 ÷ 30 = $0.50 per hour: excellent value
• If you watch 2 hours/month: $15 ÷ 2 = $7.50 per hour: poor value vs. renting at $3–5/hr

Break-even usage:

Break-Even Uses = Monthly Cost ÷ Equivalent On-Demand Price Per Use

If a gym costs $50/month and a day pass is $12, you break even at:
50 ÷ 12 = 4.2 visits/month. If you go less than that, the subscription is not cost-effective.

Annual perspective:

Always calculate annual cost, not just monthly. A $12.99/month subscription costs $155.88/year. Many subscriptions “feel cheap” monthly but add up significantly when viewed annually. Five of them at $10 to $15 each is $600 to $900 a year, which is a figure most people would refuse if it arrived as one bill.

When to keep a subscription:

• Cost per use is significantly below equivalent on-demand pricing
• You use it consistently every month
• Canceling would be inconvenient (e.g., data or account features lost)
• The subscription provides something unavailable à la carte

When to cancel:

• Cost per use exceeds on-demand alternatives
• Usage has dropped below break-even for 2+ consecutive months
• You forgot you had it (subscription creep)

Subscription creep warning: in a 2022 C+R Research survey of 1,000 US adults, people guessed they spent about $86 a month on subscriptions. Walked through category by category, the same people came to $219. Most of the gap is services on autopay that nobody looks at, and 42% admitted paying for one they had stopped using.
