What is the Subscription Cost Calculator?
Streaming services, software tools, gym memberships and apps all add up — often quietly. The Subscription Cost Calculator lets you enter the monthly fee of each subscription and instantly see the combined total you pay every month and over a full year. Seeing the annual figure is a powerful budgeting wake-up call: a "cheap" $14.99 service is really $179.88 a year.
How to use it
Enter the monthly price of each subscription in the available fields. Leave any unused fields at zero. The calculator sums every fee to get your total monthly cost, then multiplies by 12 to project your yearly spend. Currency is up to you — just keep all entries in the same currency.
The formula explained
The math is simple but useful. First we add all monthly fees together: \( \text{Monthly} = f_1 + f_2 + \ldots + f_n \). Then we annualise it: \( \text{Yearly} = \text{Monthly} \times 12 \). Because the multiplier is constant, every dollar of monthly spend equals twelve dollars per year — a handy rule of thumb when deciding whether to keep a service.
Worked example
Suppose you pay $9.99 for music, $15.49 for video streaming, and $4.99 for cloud storage. The monthly total is $$9.99 + 15.49 + 4.99 = \$30.47.$$ Multiply by 12 and your yearly cost is $$30.47 \times 12 = \$365.64.$$ That single number makes it far easier to judge value than three separate monthly prices.
FAQ
Does it handle annual plans? Convert an annual plan to monthly by dividing its yearly price by 12, then enter that figure.
What about taxes or fees? Enter the actual amount billed (including tax) for the most accurate total.
Can I compare to my income? Yes — divide the yearly total by your annual income to see what percentage of your earnings goes to subscriptions.
