The cheapest way to buy Bitcoin in Singapore

What all-in cost really means

Most fee comparisons in Singapore stop at the trading fee, the percentage a platform puts in large type. That figure is rarely the biggest part of what you pay. To know what a Bitcoin purchase really costs, you have to add up every point where money leaks between your bank account and the coins arriving where you want them.

There are four places it happens. First, getting SGD in: free by PayNow on most licensed platforms, but not always by FAST, and expensive by card. Second, the trading fee itself. Third, the spread, the gap between the price you pay and the true market price, which instant-buy screens tend to widen quietly. Fourth, getting things out: a network fee if you withdraw coins to your own wallet, and a fixed fee when SGD goes back to your bank.

One cost you can ignore: since 1 January 2020, buying and selling digital payment tokens has been exempt from GST in Singapore, according to IRAS. So there is no tax line on the bill.

Maker, taker and the instant-buy markup

On an order-book exchange, everyone’s buy and sell orders sit in a queue. If you place an order that matches one already waiting, you “take” liquidity and pay the taker fee. If you place a limit order that waits in the queue for someone else to match, you “make” liquidity and pay the maker fee, which is usually lower.

The difference is small in percentage terms but adds up. Coinbase’s Advanced trade lists 0.4% maker against 0.6% taker. CEX.IO’s low-volume tier is 0.15% maker and 0.25% taker. OKX’s global spot schedule is around 0.08% and 0.10%; we could not confirm the exact OKX SG schedule, so check it in the app.

Instant-buy screens work differently. You see one all-in price and press buy. The platform fills your order and prices in a margin. Coinbase’s simple trade uses a spread of around 0.5% on top of a fee. Gemini’s standard app lists a 1.49% fee plus a 1% convenience fee, nearly 2.5% before you have done anything else. Many platforms have both screens: the cheapest Bitcoin on Coinbase or Gemini is usually on their advanced view, not the home screen.

The published fees we used

Every number in the examples below comes from a platform’s own fee page or, where marked, a secondary source, checked on 20 October 2026. We left out anything we could not confirm, such as Crypto.com’s app spread, rather than estimate it.

Independent Reserve

Trading 0.50% at entry, falling to 0.02% with 30-day volume. PayNow deposit free up to S$200,000; FAST free from S$1,000, otherwise S$2.50; FAST withdrawal S$1.50.

OKX SG

Around 0.08% maker / 0.10% taker on the global spot schedule (Singapore schedule not confirmed). PayNow deposits and FAST withdrawals free.

Coinhako

0.6% on SGD spot trades, 0.5% on recurring buys, 0% on USD stablecoin pairs. SGD withdrawal around S$2 and GrabPay funding 2.8%, both from secondary sources.

Coinbase

Simple trade spread around 0.5% plus a fee; Advanced 0.4% maker / 0.6% taker. FAST and PayNow deposits.

Gemini

Standard app 1.49% plus 1% convenience fee; ActiveTrader has its own volume tiers. PayNow free; SGD withdrawal S$3.

CEX.IO

0.15% maker / 0.25% taker at low volume; card payments 2.99% to 4.99% (third-party data). Not MAS-licensed; no PayNow.

Worked examples: S$100, S$1,000 and S$10,000

Here is what each route costs on the published fees, at three sizes. We assume a free PayNow deposit unless the route says otherwise, and we show the fee and markup only. Order-book routes also carry a small spread, typically much smaller than the fee on a liquid pair like BTC/SGD, but it moves with the market, so we have not added a number for it.

On S$100, the absolute amounts are small, and convenience can reasonably win. But notice the Independent Reserve FAST row. A S$2.50 fixed fee on a S$100 deposit is 2.5% of your money, five times the trading fee. Fixed fees punish small amounts; the cure is simply to use PayNow there.

On S$1,000, the spread between routes becomes real money. The cheapest order-book route costs about a dollar; the convenience-fee app costs about S$25, and a card purchase S$30 or more before the trading fee. That gap is the price of one tap, and on a purchase you might repeat every month, it is worth an extra minute to avoid.

On S$10,000, percentages dominate everything. The difference between 0.10% and 0.6% is S$50, and between an order-book route and a 2.49% app it is around S$240. At this size, check whether your platform’s volume tiers apply, consider splitting the order into a few limit orders to avoid slippage, and remember that card routes don’t work anyway: new CEX.IO customers face daily and monthly card limits well below that. For purchases from S$50,000 upwards, an OTC desk may beat the order book; our OTC guide explains how quotes work.

Run your own numbers

The calculator below uses editable assumptions for five typical routes. Change the fee and spread to match the screen in front of you, set a fixed fee if your deposit method has one, and see where the money goes.

If you are planning to invest a fixed amount every month, run the numbers on the monthly amount, not the yearly total, because fixed fees apply to each purchase. Our recurring-buy guide has a calculator built for that.

Seven ways to pay less

1. Fund with PayNow. It is free on OKX SG, Independent Reserve and Gemini, and it avoids the fixed FAST fee some platforms charge on small deposits. Our PayNow guide compares every platform’s deposit rules.

2. Use the trading screen, not the buy button. On platforms with both, the advanced view almost always costs less. It looks intimidating once and then it is just another screen.

3. Place limit orders. A limit order at or near the current price usually fills quickly on BTC/SGD, often at the maker rate, and it caps the price you pay.

4. Avoid cards when you can. Locally issued credit cards are blocked on licensed platforms anyway. Debit card and international card routes cost several percent, which is more than a year of trading fees on most order-book exchanges.

5. Batch your withdrawals. Every withdrawal to your own wallet costs a network fee, and every SGD withdrawal to your bank may cost S$1.50 to S$3 depending on the platform. Moving coins out once a quarter instead of after every purchase can save more than shaving a basis point off trading fees.

6. Look at stablecoin pairs. Coinhako lists 0% fees on its USD stablecoin pairs. Converting SGD into a stablecoin still costs the normal SGD trading fee, so this mainly helps if you already hold USDT or USDC, or move between stablecoins and Bitcoin often. Check which pairs qualify in the app. Our stablecoin guide covers XSGD and network choice.

7. Use recurring-buy pricing where it is cheaper. Coinhako charges 0.5% on recurring buys against 0.6% on its standard SGD trades. Small, but on a monthly plan it compounds.

When cheapest isn’t the whole story

A few dollars’ saving is worthless if the platform is the wrong one. A MAS licence means your assets sit in a statutory trust, separate from the company’s own money, and there is a Singapore regulator to complain to. Check any platform in the list of MAS-licensed crypto exchanges before you chase its fee schedule, and be very wary of any “exchange” that someone you met online insists is cheaper. Our scams guide explains why fake platforms often advertise unusually low fees.

International platforms can still make sense. CEX.IO, for example, has operated since 2013 with regulated entities in the US and UK, and it accepts cards when you need speed or want coins that local platforms don’t list. It is not licensed by MAS, so Singapore protections don’t apply, and its card fees make it a convenience choice rather than a cheap one.
