Avios points calculator: how many points do you need?

Understanding how many points (and the cash) you need for British Airways flights

While BA is one of the less complex airlines for understanding how many points you need to take a reward flight, it’s still not the easiest calculation to make. I’ve made it easy by reviewing every single flight the airline makes, and storing the points and fee data for each one.

How does British Airways calculate the points needed for a flight?

BA uses a fixed table of points that’s based on the distance between the two cities. This makes it relatively easy to understand how many Avios you’ll need in each cabin.

There are some dimensions to that. Firstly (as mentioned below), the use of Reward Flight Saver, which allows you to use more points and pay less cash. On top of that, you have peak and off-peak reward pricing. This makes it cheaper on some dates and more expensive on others.

How to use the Avios Calculator

1. Select a starting city and destination in the boxes above
2. Click the “Calculate Avios” button
3. You’ll be presented with a table that breaks down the cabins on this route, and the peak and off-peak Avios needed
4. Click the “View All Avios/£ Options” button to see all the alternative points/cash options for that cabin

How do you calculate how many Avios you need?

You can use the calculator above to determine the baseline points you need from an airport to a destination on the British Airways route map. It returns the points you need for a single trip. The return trip will use exactly the same number of points; however, the taxes and fees will likely be different. It is usually much cheaper on the return flight due to high UK airport and government taxes.

If you have a 2-4-1 voucher, then this will reduce the points you need by half. I wrote a long article on the value of the American Express Companion (2-4-1) voucher. The Barclays cabin upgrade voucher will also help reduce the points you need; however, it works in a different way. Instead of needing the points for the cabin you are in, you instead pay for the points required for the cabin below. For example, if you are travelling in Business, you pay the Premium Economy rate.

Where does this data come from?

Since the Avios changes in December 2025 I’ve been finding and storing the updated points requirements for every flight that British Airways operates. These include the taxes and fees due, and across all four cabins: Economy, Premium Economy, Business and First. I did this manually by searching each route on peak and off-peak dates.

I’ve also stored the breakdown of all the available Reward Flight Saver options – so you can see how you could use more points to reduce the cash element, or use more cash to reduce the points needed.

What about the cash element of Avios redemptions?

In addition to the points required, British Airways will add a cash component to every redemption. That is partly to cover fees, such as those levied by airports or governments. In addition, there is a “carrier-imposed surcharge”. That is just a nice corporate term for BA adding a cost they retain. They are not alone in doing this; many other airlines do the same.

What BA do allow you to do is to reduce the cash element and use more Avios or visa versa. If you are points-rich, you can reduce the cash element. If you don’t have enough points, you can pay more cash. They call this mechanism Reward Flight Saver. You don’t need to do anything to activate it. When you get to the end of the process of booking an Avios flight, you’ll be given the option of using fewer points and paying more cash. You can see this in the screenshot below.

What is an Avios point worth?

I wrote a much longer article on the value of Avios points. On one hand, most people view their value as around 1p/point. On the other hand, the real value is the experience, and therefore for many there is little to no point in tracking the value of points.

I have had a number of redemptions recently, using both Avios and alternative airline frequent flyer currency, where it was a poor decision in terms of value per point. I chose to go ahead with them because I was going to get an exceptional experience: flying Emirates First, flying The Residence with Etihad and trying out the Singapore Airlines First suite on their A380.

Is there a good or bad Avios redemption?

You might be considering whether a flight is worth the points that it requires. That’s a more interesting question than what a point is worth. The answer, however, is deeply personal.

If you’re looking at going on holiday and you’re pretty agnostic about where you end up (beyond whatever criteria you might have, such as Europe, or the Far East) then really the most important factor is dates and availability. A good redemption is therefore one that fits with your dates and has reward seats for your whole party.

If you have a very specific route in mind, then a good redemption would be securing seats to that city. The dates may be less important.

Finally, you might have a much simpler goal in mind: to experience Business Class or First Class, and/or to have that on a specific plane type. The Singapore Airlines redemption, which used Amex Membership Rewards points rather than Avios, is a good example of this. We didn’t just want to fly First Class, we wanted to do that on their A380. That means a very specific route based on availability: Shanghai to Singapore. So although the value we got from the points was low, it was a good redemption because we got what we wanted.
