Amex to Avios
American Express Membership Rewards points transfer to Avios at 1:1, so 10,000 points become 10,000 Avios. Transfers are usually instant once your Avios account is linked, though Amex asks you to allow up to 72 hours. Periodic transfer bonuses of roughly 15 to 30 per cent are the easiest way to boost the rate.
ToolNectar to Avios converter
Nectar and Avios convert in fixed blocks: 400 Nectar points become 250 Avios, and 250 Avios become 300 Nectar. The rate is not symmetrical, so converting back and forth loses value each time. The converter runs both directions in those set blocks and shows what any balance becomes.
ToolWhat are Avios worth?
One Avios is typically worth about 1p, the working figure both the UK and US reference valuations settle near, so 10,000 Avios come to roughly £100. Weak via-hub economy redemptions land nearer 0.9p, while long-haul business can reach about 1.7p. The calculator converts any balance into pounds, dollars and euros.
ToolWhat are Marriott points worth?
A Marriott Bonvoy point is typically worth about 0.73 cents, where the published valuations cluster after the 2026 devaluation, so 50,000 points come to roughly $365. Low-category rooms land nearer 0.6 cents and high-end properties around 0.89 cents. The calculator converts any balance into dollars, pounds and euros.
ToolAvios calculator
The Avios calculator turns a year of card and everyday spending into the Avios it earns, values that total at the current typical rate, and shows how far it reaches on the reward chart. It needs no sign-up and no loyalty password, and answers in pounds, dollars and euros.
GuideHow to earn Avios
You earn Avios by flying and by spending. UK credit cards earn 1 to 1.5 Avios per £1 and Nectar converts at 400 to 250; in the US, Chase, American Express, Capital One, Bilt and Wells Fargo points transfer to Avios at 1:1. Hotels, car hire and other partners pay Avios too.
GuideHow to earn Marriott points
Marriott Bonvoy members earn 10 points per $1 at most of its hotels — 5 at Residence Inn, TownePlace Suites and Element — plus an elite bonus from 10% for Silver to 75% for Titanium and Ambassador. Marriott's co-brand cards earn up to 6 points per $1 at Marriott, and US Amex, Chase and Bilt points transfer in at 1:1.
ToolWhat are IHG points worth?
An IHG One Rewards point is typically worth about 0.55 cents, between published valuations of 0.5 and 0.6 cents, so 100,000 points come to roughly $550. Budget brands and cheap dates land nearer 0.45 cents, and better hotels or the fourth night free around 0.65 cents. The calculator converts any IHG balance into dollars, pounds and euros.
ComparisonAvios vs Amex Membership Rewards
Hold Membership Rewards until you have an Avios booking in mind. Amex points transfer to Avios at 1:1 and never expire while you keep an MR-earning Card, so they are the flexible form of the same value. Avios lapse after 36 months of inactivity and can only be spent in Avios programs.
ComparisonMarriott Bonvoy vs Hilton Honors
A Marriott Bonvoy point is worth more than a Hilton Honors point — about 0.73 cents against 0.4, per the published US valuations — so a Hilton balance has to be roughly twice the size to buy the same night. Both expire after 24 consecutive months of inactivity. Compare a specific night in cents per point, not balances.
ComparisonAvios vs AAdvantage miles
Avios and AAdvantage miles land close in value — about 1p per Avios against roughly 1.5 cents per mile — so the deciding factor is usually the cash charges, because a British Airways Avios reward adds carrier charges on top of tax. Avios expire after 36 months of inactivity; AAdvantage miles after 24.
