Should You Rely on PayPal's Conversion Rate for Your Business?

Straight answer: No, not for anything above a few hundred pounds. PayPal's currency conversion rate typically runs 3 to 4 percent worse than the mid-market rate you see on Google, and it adds up fast if you invoice international clients regularly. Keep PayPal as a payment option at checkout because customers trust it, but route the actual money conversion through something cheaper.

Two different questions hiding in one phrase

"PayPal's conversion rate" gets typed into Google by two completely different people, and they're both looking for something specific.

One group means the currency exchange rate PayPal applies when it converts a payment from dollars into pounds, or euros into shekels, or whatever crosses your account. The other group means the percentage of website visitors who buy something when PayPal sits on the checkout page as a payment option. Both matter to a small business, and I've been burned by one and helped by the other, so I'm covering both here.

The currency conversion rate: the number PayPal doesn't shout about

Here's the bit that catches people out. When someone pays you in a currency you don't hold, PayPal converts it for you automatically, and it does not use the mid-market rate, which is the actual rate banks trade at with each other and the one you see if you Google "USD to GBP" at nine in the morning.

PayPal adds a margin on top, and it's stated in their user agreement, but nobody reads that. From what I've tracked across dozens of invoices over the past few years, that margin sits at roughly 3.5 to 4 percent above the mid-market rate for most currency pairs. Some months it's closer to 3 percent, some months closer to 4.5, depending on the currency and how PayPal is feeling that week.

Let's do the maths, because a vague warning is useless without numbers.

• Say a US client pays you $8,000 for a project.
• The mid-market rate that morning is 1 USD to 0.79 GBP, so $8,000 should become 6,320 GBP.
• PayPal applies its own rate, which comes out closer to 0.758 after the markup.
• You receive 6,064 GBP.
• That's a difference of 256 GBP, gone, on one invoice.

I know this because it happened to me almost exactly like that with a US speaking client a couple of years back. I'd quoted in dollars, they paid through PayPal because it was easiest for their finance team, and I only noticed the gap when I compared what landed in my account against the rate I'd seen on my banking app that same morning. Nobody at PayPal tells you this at the point of payment. There's no pop-up saying "you're about to lose 4 percent." It just happens quietly, invoice after invoice, and most small business owners never check.

What to do instead

You don't have to stop using PayPal entirely, and I still send and receive invoices through it for smaller amounts because the convenience is real. If you've never set one up, I've written a full walkthrough on how to invoice someone through PayPal that covers the actual steps.

But for anything over a few hundred pounds, here's what I do now:

1. I open a multi-currency account with a provider like Wise Business or Revolut Business, which lets me hold USD, EUR and GBP separately without forcing a conversion.
2. When a client insists on paying via PayPal, I ask them to send it in their own currency rather than converting to mine, then I withdraw that currency into my Wise account instead of letting PayPal auto-convert it.
3. I only convert the money when the rate looks reasonable, sometimes waiting a day or two if there's no urgency, which you can't do if PayPal converts it the second it lands.
4. For repeat clients paying regularly, I now ask for bank transfer directly into my multi-currency account, cutting PayPal out of that particular transaction altogether.

The difference on a $5,000 invoice is usually somewhere between 150 and 200 pounds. Multiply that across a year of international invoicing and it stops being a rounding error and starts being a proper chunk of profit you were leaving on the table.

The uncomfortable bit nobody wants to say out loud

Here's where I'll be blunt, because most advice on this topic stops at "use Wise instead" and leaves it there. The truth is more complicated than that, and it's this: dropping PayPal entirely, even knowing what you now know about the currency markup, is often the wrong call for a small business selling to consumers.

Why? Because PayPal at checkout does something Wise and bank transfer never will, it makes strangers trust you enough to hand over their card details. If you run an ecommerce store or sell digital products, the payment method itself influences whether someone buys at all, and PayPal's brand recognition still beats almost every alternative for a first-time buyer who's never heard of your business.

So the honest position isn't "ditch PayPal," it's "use PayPal to win the sale, then get the money out through something cheaper before it converts." Treat PayPal as a trust signal on your storefront and a payment collection tool, not as your currency exchange provider. Those are two separate jobs, and PayPal only does one of them well.

Now the other conversion rate: does PayPal help you sell more?

This is where the second meaning comes in, and it's worth understanding if you're deciding whether to keep PayPal on your checkout page at all.

Cart abandonment studies consistently show that a limited or unfamiliar payment method is one of the top reasons people bail at checkout. Baymard Institute's research on checkout usability has repeatedly found that missing preferred payment options sits among the top five reasons for abandonment, and PayPal remains one of the most recognised names globally, even in markets where local alternatives exist.

Whether that translates into a meaningfully higher conversion rate for you depends heavily on where your customers are. What counts as a strong conversion rate in the US looks different from Germany or the UAE, and if you're benchmarking your own numbers, it's worth reading through what a good conversion rate looks like by country before assuming your checkout is underperforming.

If you're trying to improve on-site conversion rather than worrying about currency, the payment method is only one lever. I've written before about tactics for boosting conversions that go well beyond which payment button you show, and if your checkout involves any kind of form, there's real money sitting in fixing the form itself, which I cover in ways to optimise online form conversion rates.

The bit people forget: PayPal has fees on top of the currency markup

The currency conversion rate isn't even PayPal's only cost. There's a standard transaction fee on top, usually around 2.9 percent plus a fixed fee per transaction for most business accounts, and that's before any currency conversion happens at all. Stack the transaction fee and the FX markup together on an international invoice and you can be looking at 6 to 7 percent gone before the money even reaches your bank account.

If you're running a business with several payment tools, subscriptions and processors stacked together, it's worth stepping back occasionally and checking whether the total cost of your setup still makes sense. I did exactly that audit last year and found tools I was paying for monthly that I'd stopped using entirely. If you want a framework for doing that yourself, I wrote about it in whether your marketing tech stack is costing more than it should.

A quick way to check if you're losing money

You don't need to trust my numbers, check your own. Next time you receive a payment through PayPal in a foreign currency, do this before you spend the money:

• Note the exact amount you were paid in the original currency, and the exact amount that landed in your account after conversion.
• Search the mid-market rate for that currency pair on the day the payment was processed, not today, the actual date.
• Multiply the original amount by the mid-market rate to see what you should have received.
• Compare it to what you got.

If the gap is under 1 percent, don't bother changing anything, it's not worth the hassle for occasional small payments. If it's running 3 percent or more, which is the norm, and you're doing this regularly, that's a business cost you can fix in an afternoon by opening a multi-currency account.

So, should you rely on it?

For collecting payments from customers who trust the brand, PayPal earns its place, and there's a reasonable case that it improves your checkout conversion rate simply by being familiar. For converting the money into your own currency, no, don't rely on it, because the markup is consistent, undisclosed at the point of sale, and entirely avoidable once you know it's there. Use PayPal for the trust. Use something else for the maths. Colour, layout and psychological cues on your checkout page matter too, and if you've never tested how something as simple as button colour affects buying decisions, it's a smaller but real lever worth reading about in using colour psychology to increase traffic and conversion.

Frequently asked questions

How much does PayPal mark up its currency conversion rate?

Typically 3 to 4 percent above the mid-market rate, though it varies by currency pair and can drift higher for less common currencies. PayPal states its methodology in the user agreement, but the actual markup isn't shown to you at the point of payment.

Is there a way to avoid PayPal's currency conversion fee entirely?

Yes. Ask clients to pay in their own currency rather than yours, hold that currency in a multi-currency account like Wise Business or Revolut Business, and convert it manually when the rate looks fair, or convert it through your own bank instead of letting PayPal do it automatically.

Does keeping PayPal on my checkout page improve conversion rates?

For many stores, yes, particularly with first-time customers who don't recognise your brand yet. PayPal's familiarity reduces the perceived risk of entering payment details, which is one of the more common reasons people abandon a cart, though the size of the effect varies by market and audience.

Should small businesses stop using PayPal altogether?

No, that's usually overcorrecting. Keep it as a payment option for the trust it brings at checkout, but stop letting it convert your foreign currency automatically, and move larger international invoices to bank transfer or a multi-currency account instead.
