AI Subscription Stack Cost Calculator
Every AI tool sells you on itself, never on the total. Add each subscription you pay for and see what the whole stack actually costs you per month and per year. Nothing uploaded.

AI subscription stacking and cost management
How to calculate true cost-per-use
Cost-per-use is monthly cost divided by actual uses per month. If you subscribe to ChatGPT Plus for $20 and use it 200 times per month (about 6-7 times per day), cost-per-use is $0.10. But if you subscribe for $20 and only use it 5 times per month, cost-per-use is $4. Most people overestimate their usage. If you haven't used a tool in 2 weeks, you're probably paying for convenience, not value. Track actual monthly usage: check your dashboard, count the prompts, sum feature use requests - then calculate exact cost-per-use. Cancel tools where cost-per-use exceeds the value to you.
Annual vs monthly plans and cost optimization
Annual plans typically save 15-25% vs monthly, but only if you actually use the tool the entire year. Buying annual Midjourney ($120/year) and using it once is $120 per use. Buying monthly ($10) and canceling after one month is $10 per use. For tools you're still evaluating, buy monthly. For tools you use multiple times per week, annual plans pay for themselves within 2-3 months. Mixed strategy: use monthly for experimental tools (e.g., new specialized AI), annual for core tools (ChatGPT, Claude, Midjourney if you're a heavy creator).
FAQ
Why do I have so many inactive subscriptions?
Most people accumulate subscriptions over time and forget about them. A common scenario: subscribe to ChatGPT Plus for $20, then try Claude Pro ($20), then add Midjourney ($10), then a specialized tool ($50+). Within a year, it's easy to have 5-10 subscriptions, many used rarely or never. Add them all up with uses-per-month: if you pay $150/month but only use ChatGPT daily and Claude weekly, most of your stack is waste.
What's a reasonable cost-per-use threshold?
It depends on the tool and how often you use it. ChatGPT at $20/month used daily (200 uses) = $0.10 per use. Midjourney at $10-120/month used for 5-10 images (10-20 uses) = $1-12 per image. This calculator flags cost-per-use above $5 as high. If you're paying more than $5 per actual use on a tool, you're either using it very rarely or paying for a tier you don't need.
Should I buy annual subscriptions if offered?
Only if you're certain you'll use the tool for a full year. Annual plans usually offer 15-25% discounts but lock you in. If you're experimenting with new AI tools, stick to monthly. Once you've confirmed daily or weekly use, upgrade to annual. This calculator shows the monthly-equivalent cost of annual plans, so you can compare fairly.
