Annual vs monthly subscription: compare the team cost

A tool costs $20 per seat each month or $192 per seat paid annually. For six people, twelve monthly payments cost $1,440 and the annual plan costs $1,152. The annual saving is $288, or 20%, if the team uses all seats for a full year.

When this helps

An annual discount looks attractive, but your team may not need the tool for twelve months. Compare the same number of seats and the same service level, then check how many months of use justify paying upfront.

How to calculate it

Enter the monthly price per seat, the actual annual charge per seat and the seat count.
Multiply the monthly price by twelve and by the seat count. Compare it with the total annual prepayment.
Divide the annual per-seat charge by the monthly per-seat price to find the usage threshold in months.

Inputs and formulas

Copy these lines into Sumico or use the interactive example below. Decimal values in expressions use a dot.

# Annual or monthly plan
monthly = $20
annual = $192
seats = 6

monthlyTotal = monthly * 12 * seats
annualTotal = annual * seats
saving = monthlyTotal - annualTotal
Saving percent: saving / monthlyTotal * 100
Months to match: annual / monthly

Read the result

For six seats, annual prepayment is $1,152 instead of $1,440 over twelve months, saving $288 or 20%. The price threshold is 9.6 months: with whole monthly billing periods, the annual plan first becomes cheaper at month 10.

The calculation in Sumico

Change an assumption

Change annual = $192 to annual = $216. Annual team spend becomes $1,296, the full-year saving falls to $144 or 10%, and the threshold rises to 10.8 months. The annual plan first becomes cheaper at month 11.

Assumptions and limits

Assume identical features, stable seat counts, no refunds and no taxes or extra fees. The annual amount is the real yearly charge, not an advertised monthly equivalent. This comparison ignores the time value of money. If you use the tool for fewer months than the threshold, monthly payments are cheaper under these assumptions.

A common question

What if the annual price is shown as a monthly equivalent?

Multiply that equivalent by twelve to get the actual annual per-seat charge before entering it as annual. Otherwise you would compare one month with a full year.
