What overseas subscriptions really cost in a yearCombine the monthly fee, FX markup and number of subscriptions to see how much the markup layer quietly adds across twelve months
Here's the answer up front: the yearly cost of an overseas subscription is monthly fee × (1 + FX markup%) × 12 × number of subscriptions. A monthly fee looks small, but the FX markup stacks month after month, then multiplies across the pile of subscriptions you hold, and the yearly gap is often bigger than you'd guess. This calculator presets no fee; the monthly fee, markup and count are all your input, and the tool just multiplies them cleanly, turning "a little each month" back into "a lot each year".

How to use it / where to look
This tool totals "a batch of same-price subscriptions" for the year. To mix different prices, run it once for each and add the results yourself. Here's how to fill the three fields:
- Monthly fee. The monthly price on the subscription page. Home or foreign currency is fine, but keep it consistent with how you think about the markup; if you enter a foreign monthly fee, the yearly figure comes out in that same order of magnitude.
- FX markup %. If the subscription bills in foreign currency and your card converts it, the card usually adds a conversion fee. Enter the percentage if you know it, such as 1.5; if it bills in home currency with no conversion, leave it blank or enter 0.
- Number of subscriptions. Enter how many similarly priced subscriptions you're totting up, or 1 to look at just one.
Run it once with markup at 0 and note the yearly figure, then enter your card's real markup and run it again. Subtract the two "yearly totals" and you have the money the FX markup quietly takes from your account over a year. With that number in front of you, it's easier to judge whether switching cards or methods to shed that layer is worth it.

Questions people ask
- An annual plan is usually cheaper than paying monthly. Does the tool account for that?
- This tool estimates the yearly ceiling as "monthly fee × 12". If the provider offers a cheaper annual price, compare using that directly; this result is best for seeing the order of magnitude of paying monthly for a full year, and how big a share the markup is.
- Is there a difference between leaving markup blank and entering 0?
- No; both calculate with no markup. Only enter a real percentage when you know your card charges a conversion fee and want to see how much it adds over a year. Check your card's fee terms for the figure, and don't borrow someone else's.
- Is this total the exact amount I'll be charged?
- No; it's a teaching estimate. The real bill also depends on settlement-date rate movement, price rises, free-trial periods, annual discounts and more. Go by the subscription's checkout page and your issuer's statement; this tool only helps you see the order of magnitude.
Note: this tool goes online for nothing and stores none of what you type; the calculation runs locally in your browser. The monthly fee, markup and count are your input, and the result is a directional estimate meant to show the order of magnitude for a year, not any provider's actual charge or a promise.
