Why does my subscription charge change from month to month?

A subscription can charge a different amount from the price you remember for several reasons: currency conversion, a card fee, tax added at checkout, a price increase, a change of plan partway through a billing period, or the end of a trial or introductory price. Each section below covers one, and the last one shows how to check a charge.

Why is my subscription charge different every month?

If the listed price hasn't changed, the service may bill you in a different currency from your card's, and each charge is converted at the exchange rate when it goes through. Exchange rates move, so the amount on your statement can change a little every month.

Visa says that since April 2021 it has applied the exchange rate available when a payment is authorized, or the rate when the transaction is processed if it can't use that one. The CFPB's credit card contract definitions say the rate on the date the card network processes a transaction may differ from the rate on the day you made it or the day it posts to your account. Visa also says your bank may not use Visa's rate to bill you and may add fees for foreign transactions.

Say a tool costs €10 a month and your card is in US dollars. If the rate is $1.08 per euro one month and $1.12 the next, you are charged $10.80 and then $11.20, even though the price in euros never changed.

Google Play can also bill you in a currency you don't expect. Google says it charges you in the currency of your home country if possible, based on the home address you added. If that isn't possible, it charges a different currency, which for people outside the United States usually means US dollars. Google shows the currency before you complete the purchase.

Why was I charged a foreign transaction fee on a subscription?

Your card issuer may charge one when you pay in a foreign currency or buy from a business based in another country, and that includes buying online from home. In its guide to prepaid card fees, the CFPB says this fee, sometimes called a currency conversion fee, is usually a percentage of the transaction rather than a flat fee.

Paying in US dollars doesn't always avoid it. For credit cards, the CFPB's official commentary on Regulation Z counts fees on purchases from a foreign merchant, including through the merchant's website, as foreign transaction fees whether the purchase is in a foreign currency or in US dollars. In its example, the card network may charge 1% and the bank may add 2%, for 3% in total.

Using that 3% as an example, the $11.20 charge above would cost $0.34 more (3% of $11.20 is $0.336), for $11.54 in total. Your own card's fee may be different, so check what your card issuer charges.

Some sites offer to charge you in your own currency instead of theirs, so the merchant does the conversion. The EU's consumer guidance says paying in the merchant's local currency is often the cheapest option, and that the extra fees often make paying in your home currency more expensive, even though you see the exact amount right away. In the EU, a trader or website that offers this must tell you exactly how much extra it will cost, which should be shown as a percentage mark-up over the European Central Bank's latest exchange rates, and you can always say no. Visa notes that if the merchant converts the payment, the rate from Visa's exchange rate calculator doesn't apply.

Why is my subscription charge higher than the listed price?

Tax may be added at checkout. Whether a listed price already includes sales tax or VAT depends on where you live and who sells the subscription:

App Store: Apple's developer glossary says the customer price includes the taxes Apple collects and remits, except in the United States and Canada, where sales tax is added to the amount billed.
Google Play: Google says you always see the tax on the checkout screen before you complete a purchase. For apps, the developer is responsible for charging tax in most locations, while Google charges the VAT for customers in the UK and EU. Where Google is the seller in the US, sales tax depends on your state's tax laws and is based on your legal address.
In the EU: the EU's consumer guidance says you have to be clearly informed of the total price, including all taxes and additional charges, when you buy goods or services.
A service's own website: check whether its pricing page says prices include tax, then compare that with your receipt.

If you have moved, update your address. Google says you can update your home address so you're charged in your home currency, and where Google is the seller in the US, it bases sales tax on your legal address. An out-of-date address can mean a different currency or tax from what you expect.

Can a subscription raise its price without asking me?

On the App Store and Google Play, yes, within limits: a smaller increase can take effect after advance notice, while a larger one needs you to agree first.

Apple: Apple notifies you before an increase by email, push notification and a message in the app. A developer can raise the price without your agreement only if the increase is no more than about US$5 and 50% of the price (US$50 and 50% for yearly plans), where the law allows it, and no more than once a year. Above that, or where the law requires it, you must opt in. If you don't, the subscription doesn't renew at the next billing period.
Google Play, opt-in increases: you must agree to the higher price before it takes effect, with at least 30 days to respond. If you don't agree, the subscription is canceled before the first charge at the higher price.
Google Play, opt-out increases: in certain countries, a developer can raise the price without your agreement after a notice period of at least 30 or 60 days, depending on the country. The increase can be no more than 50% of what you pay now or 17 US cents a day, whichever is greater, and a plan can have only one in 365 days in each country. At least 30 days before, the app must show you a notice with your current and new price, the date the new price starts and how to cancel.

If you don't want to pay the new price, cancel before it takes effect. See how to cancel an Apple subscription or how to cancel a subscription on Google Play. When a renewal notice arrives, the FTC says to read it closely to confirm the rate is what you expected, and to call the company right away if it isn't or if the notice doesn't say how much you'll pay.

Why was I charged an odd amount after changing plans?

Switching plans partway through a billing period can lead to a prorated charge: the unused part of your old plan is credited, and you pay the difference or your next billing date moves.

On Google Play, Google says that depending on the subscription, you may pay the full price of the new plan or the price difference, and that the app's developer can tell you how the rest of your current plan is credited. Google's developer documentation shows how much this can vary. In its example, a subscriber on a $2 monthly plan that renews on the 1st switches on April 15 to a $36 yearly plan. Depending on the method the developer chose, the subscriber is charged:

$0.50 right away, the difference for the rest of April, then $36 on May 1.
Nothing extra right away, then $36 on May 1.
$36 on April 26, because the $1 credit for the unused half of April covers 10 days of the new plan.
$36 right away, with about 10 days added to the first year for the unused half of April.

On the App Store, Apple's developer guidance says an upgrade takes effect right away and you get a refund of the prorated amount of your original subscription. A downgrade waits until your next renewal date, then renews at the lower level and price. So an upgrade can show up as a new charge plus a partial refund.

Changing plans can also end an older, lower price. On Google Play, when a developer changes a price, subscribers who were paying the previous price keep paying it until they change plans or the developer moves them to the current price.

Why did my subscription price go up after the first few months?

A free trial or introductory price may have ended. On the App Store and Google Play, once the offer period is over, the subscription renews at the standard price.

One example in Apple's developer guidance is $1.99 a month for three months on a plan that normally renews at $9.99 a month. Once the three months are over, the subscriber is billed the standard renewal price, so in that example the fourth charge is $8.00 higher. On Google Play, the first billing period begins when a trial ends, and you are charged the amount in your subscription terms. The FTC notes that an automatic renewal might charge more than you paid the last time if you first had a promotional rate.

Before you cancel to get a deal back, know two things:

Google says promotional discounts tied to a subscription are lost when you cancel it.
The FTC says you can sometimes cancel and resubscribe for a better promotional rate. If you do, note exactly when the new promotion ends and how much you'll be charged after it.

To catch a trial before it turns into a paid plan, see how to avoid being charged after a free trial.

How do I check what I should be paying?

Compare three things: the charge on your statement, the receipt from whoever billed you and the price you signed up for.

Open the charge in your card's app or online statement. Look for an amount in another currency, an exchange rate and any separate foreign transaction fee. If those details aren't there, ask your card issuer which currency the charge was in and what fees it added.
Find the receipt. Google Play sends a confirmation email with your order information when you buy. To see your order history, go to play.google.com, click your profile icon, then Payments & subscriptions, then Budget & order history. For Apple, sign in at reportaproblem.apple.com to see your purchases, and if you only know the amount, search for it. Apple may group several purchases and subscriptions into one bill, so one charge can cover more than one item.
Check the price you signed up for in the confirmation email from the day you subscribed or on the plan page of your account. If a renewal notice shows a different rate, contact the company before the renewal date.
Turn every price into a monthly and a yearly figure so plans with different billing cycles compare fairly. The subscription cost calculator does this for you.

If you're not sure what you pay for, start with how to find all your subscriptions. Subskim, a free subscription tracker, keeps each subscription in the currency it bills in and converts your totals into your main currency.
