The Authentication Rate
In the online payment universe, the authentication rate acts like a goalkeeper. It ensures that those attempting to pay are really who they claim to be. This is where the famous 3DS comes into play.
3D Secure (3DS) adds an extra layer of security, usually through additional verification (or double authentication), like validating the transaction through a banking app. It's a crucial step to ensure that the person using the credit card is the legitimate owner.
3DS identification is a primary source of payment failure, so it's essential to minimize its impact while limiting fraud. The authentication rate measures the effectiveness of this process: the higher it is, the more confident you can be that the transactions on your site are legitimate. A good authentication rate stops fraudulent attempts while allowing secure payments.
For the examples in this guide, we assume that 100% face a 3DS request. You can learn more about 3DS exemption later in the section “How to Improve My Conversion Rate”.
The authentication rate is calculated by dividing the number of successfully authenticated payments by the total payments that required authentication.
For instance, the fictional e-merchant ABC notices that out of 100 payment attempts, 95 pass authentication. Therefore, its authentication rate is 95%.

The Authorization Rate
This rate represents the proportion of transactions that are not only successfully authenticated but also approved by card networks (e.g., Visa, Mastercard, or Carte Bancaire). Your payment service provider (PSP) acts as a middleman between you and the consumer's card. It transfers payment information to the appropriate card network and returns to you to confirm or deny the payment.
A payment can be refused by card networks for several reasons, such as insufficient funds, incorrect card information, expired card, credit limit exceeded, suspicious activity or fraud, or technical issues.
A high authorization rate is a positive sign. It indicates that most transactions are not only secured by 3DS but also accepted by card networks, leading to successful transactions and a smooth user experience. It's crucial for customer trust and the efficiency of online payment operations.
To calculate this rate, start by examining the total number of transactions given the green light after the 3DS authentication step. This number is then divided by the total number of transactions submitted to the card networks after authentication.
For example, let's take the fictional e-merchant ABC again. Out of its 95 authenticated transactions, 92 are approved, resulting in an authorization rate of 96.8%.

The Conversion Rate
The conversion rate represents the payment attempts that end in success. It's perhaps the most important and representative indicator of your performance. It reflects the proportion of successful payments compared to the total number of payment attempts.This rate takes EVERYTHING into account: 3DS identification, blocked/erroneous transactions, and even expired payments, where the customer may have just hesitated a bit too long. And to keep things simple and clear, we don't apply user deduplication – each payment attempt counts, to give you a complete and clear picture of your customers' journey.To calculate this rate, take the total number of successful payments
and divide it by the total number of payment requests. The result is a percentage indicating how effective you are at converting attempts into successes.A high conversion rate is like defeating the final boss in a game: it means you've mastered the art of turning visitors into satisfied buyers. In the e-commerce game, this is one of the keys to winning.For instance, the fictional e-merchant ABC, out of the 100 payment transaction, 94 are converted after authorisation and authentification, yielding a conversion rate of 94%.

The Acceptance Rate
This rate is similar to the conversion rate but with an important distinction: it includes user deduplication, meaning it only considers the final outcome for each unique customer, not every individual attempt.
This metric offers an overview of the overall success of payments but doesn't provide a detailed picture of individual challenges or obstacles customers face during each payment attempt. Therefore, while useful, the acceptance rate doesn't always give complete visibility into the customer journey, unlike the conversion rate.
For example, continuing with the fictional e-merchant ABC, imagine that 3 out of the 92 authorized customers couldn't complete their purchase initially due to insufficient funds. They then decide to use Klarna to pay in three installments without fees, and the purchases are completed. The acceptance rate will record 97.8%, reflecting the final success of the customer in making a payment. However, the conversion rate in this case would be 94.6%, as it considers the customers' two attempts separately. The result is the same, but the conversion rate gives a better understanding of your customers' experience and journey.

Better Differentiating the 'Fab Four'
The authentication, authorization, and conversion rates all represent key moments in the customer journey. It's easy to confuse or not distinguish between the conversion rate and the acceptance rate. The acceptance rate will always be higher as it doesn't show each client's attempt. The conversion rate gives you better visibility into your consumers' payment journey.
If you are looking for a payment partner to help improve your performance, choose one that is transparent and will support you in your growth and in analyzing your performance.
