How to use this calculator
- Type each price into Monthly subscriptions, separated by commas (for example 15.49, 11.99, 9.99).
- Convert yearly plans first: divide the annual price by 12 and enter the result.
- Set Return if invested instead to a cautious rate and choose the number of Years.
- Read the Monthly total and Yearly total, then compare Total over the period with Value if invested instead.
How the totals are calculated
The calculator adds all the prices you enter to get one monthly total, multiplies it by 12 for the yearly figure and by the number of months for the total over the period. That part is simple addition, but it is the number most people have never actually seen in one place.
FV = M · ((1 + r)^n − 1) / r- FV = value of the money if invested instead
- M = combined monthly subscription cost
- r = monthly rate, equal to (1 + annual return)^(1/12) − 1
- n = number of months (years × 12)
The investment figure treats the monthly total as a contribution made at the end of every month into an account earning a steady return. It uses the future value of an annuity, with the annual return converted to an equivalent monthly rate.
Example: five common subscriptions
Take five services at $15.49, $11.99, $9.99, $6.99 and $14.99 a month. Together they cost $59.45 a month and $713.40 a year. Over 10 years that is $7,134 spent.
If the same $59.45 were invested every month at 6% a year instead, it would grow to about $9,659 after 10 years. The gap between the two figures is growth you give up, which is the opportunity cost of keeping everything.
Spotting what to cancel
The goal is not to cancel everything, only to stop paying for things you no longer use. Go through each line and ask when you last opened it. Services you use weekly usually earn their place; those you forgot about rarely do.
Drop the $6.99 service from the example and the monthly total falls to $52.46; the invested alternative over 10 years becomes about $8,523. Removing one item you barely use is worth roughly $1,100 over a decade in this scenario.
Ways to pay less without losing what you value
- Rotate streaming services: subscribe for a month, watch what you want, cancel, and return later.
- Compare annual and monthly plans; annual billing is often cheaper but only if you will use it all year.
- Look for family or student plans and bundles before paying individual prices.
- Check your bank statements for small recurring charges you do not recognize.
- Put the saved amount into a goal with the savings goal calculator so the money does not simply disappear into other spending.
Putting the number in context
Compare the yearly total with your overall plan. Subscriptions belong in the "wants" part of a monthly plan, which you can lay out with the budget calculator. To see how a recurring amount grows over time in more detail, use the compound interest calculator.
Assumptions and limits
The tool assumes prices stay flat, which they rarely do; many services raise prices every year or two, so the real cost may be higher. The invested figure assumes a constant return with no taxes, fees or market losses, and returns are never guaranteed. Treat it as an illustration of opportunity cost, not a forecast or investment advice. Free trials that convert to paid plans, one-off purchases and usage-based charges are not included unless you add them as monthly amounts.
Frequently asked questions
How do I enter a yearly subscription?
Divide the annual price by 12 and add the result to the list. A $120 yearly plan is entered as 10.
How much do the average person's subscriptions cost?
It varies widely, so use your own list. Many households are surprised that a handful of small charges adds up to several hundred dollars a year.
What return rate should I use for the invested comparison?
Use a modest figure that you would be comfortable with over the long term. A lower rate gives a more conservative comparison, and 0% simply shows the total spent.
Does this include free trials?
No. Add a trial only once it becomes a paid plan, using its regular monthly price.
Is it worth cancelling a cheap subscription?
If you rarely use it, yes. A $7 charge is $84 a year, which is more than most people expect for something they do not value.
