Any two plan quotes
When does a lower
percentage pay off?
Compare a monthly charge and a percentage of sales. Use the same currency for every amount.
Same modeled platform cost at
$3,500.00
in monthly product sales.
Above this amount, Plan B costs less. Below it, Plan A costs less.
At your product price, this is approximately 121 sales per month. An exact tie may fall between sales.
The formula
Revenue = (monthly B − monthly A) ÷ ((rate A − rate B) / 100)
The calculator compares platform fees only. It assumes payment processing and any per-transaction fixed charges are identical on both plans, so those charges cancel out. It cannot compare plans with different fixed fees per order or different included services.
If one plan is cheaper both per month and per sale, there is no positive crossover. Equal percentage rates also have no crossover unless both monthly charges are identical.
For annual subscriptions
Divide an annual subscription by 12 only when you want an average monthly cost comparison. You may still have to pay the entire year upfront. A low monthly equivalent does not remove that cash requirement.
