Why subscription math is deceptive

Vendors price subscriptions to minimise the number on screen. $5/week sounds trivial; $260/year is more sobering. Quarterly billing hides the annual cost behind infrequent charges. This calculator converts any billing frequency into a consistent monthly and annual view.

Worked example. A $15/month subscription costs $180/year. A $5/week one costs $260/year — nearly 45% more, even though the weekly amount feels smaller.

The formula

Annual cost = amount × multiplier, where multipliers are: weekly × 52, monthly × 12, quarterly × 4, yearly × 1. Monthly equivalent = annual ÷ 12.

Subscription audit tip

List every subscription with this calculator and sort by annual cost. Most people find at least one forgotten service they no longer use. Cancelling even two mid-tier subscriptions often saves several hundred dollars a year.

Frequently asked questions

How do I convert a weekly subscription to an annual cost?

Multiply the weekly amount by 52. A $5/week streaming service costs $260 per year — more than most annual plans sold at a discount.

Why is the monthly equivalent different from what I actually pay monthly?

When billing is weekly or quarterly, the monthly equivalent is a calculated average (annual cost ÷ 12). Your actual bank statement will show different amounts depending on how many billing cycles fall in a given month.
