Methodology
How currency.ae works
Everything here reflects exactly what the site does. Where a number carries a caveat, we state it.
Where the rates come from
Live rates are sourced from fastForex, a foreign-exchange data provider, and are mid-market rates — the midpoint of the interbank buy/sell price. This is a reference rate: it is not the price a bank or exchange will give you, which includes their margin.
Updated every 60 seconds
We fetch fresh rates and cache them at the edge for 60 seconds, so everyone who visits within the same minute sees the exact same numbers. The "updated X seconds ago" indicator counts from when we received the data.
How any pair is calculated
We hold every rate as "units per 1 US dollar" and derive any pair by a single division. The dirham is not treated specially — AED is one currency among many, and USD is only the common anchor the maths pivots on. So AED→EUR, GBP→INR, or any other pair is computed the same, honest way.
The 1-day change
The green/red change figure compares the current rate to the previous trading session's close. Because FX markets are shut on weekends and holidays, "yesterday" is often frozen — so we look back over recent days and use the most recent session that actually moved. It's an honest "vs previous close", not a fabricated daily wiggle.
History & the timing verdict
Each pair's chart shows up to 365 daily observations, subject to provider availability — each the provider's daily closing rate (UTC-based), so weekend and holiday gaps are normal — with the live "now" point appended from the 60-second feed. Above it, a one-line verdict describes the selected range (7 days, 30 days, or 1 year) in plain language, by these rules:
- Held steady / pegged — the rate barely moved across the window.
- Little changed this week — a quiet 7-day window with no meaningful net move (we won't dress up noise as a trend).
- At its strongest / weakest — the rate currently sits at the high or low of the window.
- Up / down X% — a genuine move, stated as a plain percentage.
The chart's vertical scale never exaggerates: a change under about half a percent renders as a near-flat line, so the picture always agrees with the words.
The cost of exchanging money
Our Typical costs calculator shows what an amount is worth at the mid-market rate, then what you would typically receive once a bank, exchange house, or card adds its margin. It applies a typical proportional margin (the "spread") to the mid-market value — cost = amount × margin — so the estimate stays honest at any amount.
Spread vs. all-in cost. Widely-quoted figures — for example the World Bank's finding that banks are the most expensive way to send money, around 13–15% — are all-in costs on a small (about USD 200) transfer, where a flat fee dominates the percentage. That is not the proportional spread our calculator applies, so we don't use those headline numbers as the margin; we use the typical spread and note that small transfers cost more once flat fees are added on top.
These are the typical, illustrative ranges we use — not quotes, and not tied to any named institution:
- Bank — about 2–4%. Banks are consistently the costliest channel in the World Bank's Remittance Prices Worldwide, and the ACCC's 2019 foreign-currency inquiry documented that banks add a large, often opaque margin over the mid-market rate.
- Exchange house / transfer — about 1–3%. Money-transfer operators average well below banks in Remittance Prices Worldwide, and UAE exchange houses are typically leaner still — the UAE is among the least expensive places in the world to send money from.
- Card abroad — about 1–3%. A card's foreign-transaction fee is commonly around 1–3%; its existence and structure are described in the US CFPB's Consumer Credit Card Market Report. Cash advances cost far more — the CFPB's cash-advance data shows a typical 30% APR charged from day one — and accepting "pay in your home currency" (dynamic currency conversion) adds a further ~7.6% on average (up to ~12.4%), per the Norwegian Consumer Council's study.
As a public benchmark, the UN Sustainable Development Goal 10.c targets remittance costs of under 3% and the elimination of any corridor above 5% — a bar the global average (still above 6%) has yet to meet. It is the neutral frame for why the honest mid-market number matters. See UN SDG 10.
These are typical ranges for orientation, not a quote for any specific transaction, and we name no institution. We review them when the World Bank's figures update. Ranges last reviewed: 25 July 2026.
Crypto data
The crypto section — the market table, each coin's profile, and the AED↔crypto side of the converter — is separate from the fiat rates above and sourced from CoinGecko. One important honesty note: our "no markup, mid-market" promise applies to fiat only. A cryptocurrency has no single interbank midpoint, so for crypto we show the real market price as reported by CoinGecko — sourced and timestamped — never a mid-market or markup-free claim.
- Source & refresh cadence. A scheduled worker pulls the top ~250 assets by market capitalisation from CoinGecko roughly every two minutes into a cached snapshot. Every visitor is served from that one cached copy — the page makes no per-visitor call to CoinGecko — and each snapshot carries the timestamp shown on screen.
- Fresh price on interaction. When you use the AED↔crypto converter we additionally fetch a single fresh price for that one coin directly, so a conversion reflects the up-to-the-moment number rather than the cached snapshot.
- 7-day trend. A coin profile's sparkline is CoinGecko's real 7-day price series (hover for date & price), shown alongside the actual 24-hour and 7-day percentage moves. This is real history — unlike gold, which our fiat provider gives us no series for.
- Market cap, volume & supply. Market capitalisation, 24-hour trading volume, circulating supply and the all-time high are shown as reported by CoinGecko, each carrying the snapshot's timestamp.
- AED conversion. Crypto values are quoted in AED natively from CoinGecko (with USD alongside), the same dirham-first way the rest of the site works.
- My Portfolio is private to your device. The optional portfolio tracker is entirely client-side: your holdings and the cost basis you enter live only in your browser's local storage and are never sent to us. There is no account. Profit/loss is calculated on your device from the live price against the cost basis you typed — we never see your positions. (See Privacy.)
- CBDCs are shown for reference, with no price feed. Central bank digital currencies such as the Digital Dirham are listed for education only. Their value is definitional (one Digital Dirham is one dirham; the e-CNY is a digital form of the yuan), so we attach no market price, chart, or percentage move to them — we label them plainly rather than imply a live market that doesn't exist.
Honest disclosures
These are the caveats we make in the product, gathered in one place:
- Gold is a tokenized proxy, not official spot. Our gold figure comes from PAXG (Pax Gold) — a token redeemable 1:1 for a troy ounce of LBMA-certified gold — quoted against USDT (≈ USD). We label it as tokenized gold and show it under its own code, PAXG. We never present it as official XAU spot. USDT is designed to track the US dollar but may trade slightly above or below it.
- Gold shows a live price, not a chart. Our fiat data provider supplies daily history for currencies only, so tokenized gold (PAXG) shows a live price but no chart; the history section says so — naming the asset on screen — rather than showing an empty frame. Crypto is different: the crypto assets carry a real 7-day price trend sourced from CoinGecko — see Crypto data below.
- Pegged pairs are shown as fixed. Where two currencies are pegged (for example the dirham to the US dollar, or two Gulf currencies that both peg to the dollar), we label the rate as effectively fixed and explain it, instead of implying a live market movement. Pegs differ in kind — some are hard pegs, others are managed regimes — and because we derive cross-rates from provider data, a pegged rate may vary slightly rather than sit at an exact round number. Why the dirham is pegged to the dollar →
- Reference rate, not a transaction rate. Everything here is for information. Rates are not an offer to transact and will differ from what a bank or exchange quotes. See Terms.
