Cheapest Way to Buy Bitcoin in 2025: Complete Cost Comparison
The difference between the cheapest and most expensive way to buy $1,000 of Bitcoin? Over $40.
The cheapest way to buy Bitcoin in the US is Kraken Pro with a limit order funded via ACH. Total cost: ~0.16% ($1.60 per $1,000). The most expensive common method is buying on Coinbase with a debit card: ~4.5% ($45 per $1,000).
The True Cost Formula
Most comparisons only look at trading fees. But your actual cost to buy Bitcoin includes multiple components:
Total Cost = Deposit Fee + Trading Fee + Spread
Deposit Fee
Cost to get USD into the exchange (ACH, wire, card)
Trading Fee
The explicit fee charged per trade (maker/taker)
Spread
Hidden cost: difference between buy/sell price
Why This Matters
An exchange advertising "0% trading fees" might still cost you 1-2% via spread markups. Always calculate total cost, not just the advertised fee.

Step-by-Step: The Cheapest Way to Buy Bitcoin
-
1
Create a Kraken account
Complete identity verification (takes 1-2 days). This is required for all US exchanges.
-
2
Link your bank account for ACH transfers
ACH deposits are free. Avoid debit/credit cards which add 2-5% fees.
-
3
Deposit USD via ACH
Takes 1-3 business days to clear. Plan ahead if you want to buy at a specific time.
-
4
Go to trade.kraken.com (Kraken Pro)
Don't use the basic "Buy Crypto" page—it has higher fees. Use the Pro trading interface.
-
5
Place a limit order (not market order)
Set your buy price slightly below the current price. This makes you a "maker" and gives you the lowest 0.16% fee.
-
6
Wait for your order to fill
Your limit order will fill when the market reaches your price. Total cost: just 0.16%.
Deposit Method Matters More Than Exchange Choice
Here's something most guides miss: your deposit method often costs more than the trading fee itself. Compare the costs:
| Deposit Method | Cost | Speed | Verdict |
|---|---|---|---|
| ACH Bank Transfer | Free | 1-3 days | Best Value |
| Wire Transfer | $0-$25 | Same day | Large Amounts |
| Debit Card | 2-3.5% | Instant | Emergency Only |
| Credit Card | 3-5% | Instant | Avoid |
Credit Card Warning
Most credit cards classify crypto purchases as "cash advances," adding an extra 3-5% fee plus immediate interest. A $1,000 Bitcoin purchase could cost you $50+ in fees before you even own the BTC.
Speed vs. Cost: What's the Trade-Off?
The cheapest method (ACH + limit order) takes 1-3 days. Here's how to think about the trade-off:
🐢 Cheapest (1-3 days)
ACH deposit → Wait → Limit order
Cost on $1,000: ~$1.60
Best for: Regular purchases, DCA strategy, long-term investors
🐇 Fastest (Instant)
Debit card → Market order
Cost on $1,000: ~$25-35
Best for: Emergencies only (market crash you want to buy)
What About Bitcoin ATMs, PayPal, and Cash App?
🏧 Bitcoin ATMs
Fees typically range from 5-15%. Convenient but extremely expensive. Only use if you have no other option.
Verdict: Avoid unless necessary
📱 PayPal / Venmo
~1.5-2.3% fees depending on purchase size. Convenient but you can't withdraw BTC to your own wallet.
Verdict: Okay for beginners, but limited functionality
💵 Cash App
~1.5-2.5% spread on Bitcoin purchases. Unlike PayPal, you CAN withdraw to your own wallet.
Verdict: Reasonable for small, casual purchases
📈 Bitcoin ETFs (IBIT, FBTC)
0.19-0.25% annual expense ratio. No trading fee if your broker offers free stock trades. But you don't own actual Bitcoin.
Verdict: Great for retirement accounts, but not real BTC ownership
Don't Forget Withdrawal Fees
If you're moving Bitcoin to your own wallet (self-custody), you'll pay a withdrawal fee. This varies by exchange and network conditions:
| Exchange | BTC Withdrawal Fee | Lightning Network |
|---|---|---|
| Kraken | ~0.00002 BTC (~$2) | ✓ Supported |
| Coinbase | Dynamic (network fee) | ✓ Supported |
| Gemini | 10 free/month, then dynamic | ✗ Not yet |
| Robinhood | Dynamic (network fee) | ✗ No |
Lightning Network Tip
If your wallet supports Lightning Network, use it for withdrawals. Fees are typically under $0.10 vs. $2-10+ for on-chain transactions.
Frequently Asked Questions
Is Robinhood cheaper than Coinbase for buying Bitcoin? ▼
Robinhood's spread (~0.30-0.40%) is comparable to Coinbase Simple's fees. For the cheapest option, use Kraken Pro or Gemini ActiveTrader, both of which beat Robinhood's hidden spread costs.
Can I buy Bitcoin with no fees at all? ▼
No. Every platform makes money somehow. "Zero fee" platforms like Robinhood use spread markups. The closest to free is Kraken Pro at 0.16% maker fees—on $1,000, that's just $1.60.
Is it worth saving 0.2% on fees? ▼
Depends on your volume. On $10,000/year of purchases, 0.2% = $20 saved. On $100,000, that's $200. For active traders buying/selling frequently, fee differences add up to thousands.
Should I just use a Bitcoin ETF instead? ▼
ETFs like IBIT (0.25% annual fee) are great for retirement accounts or if you don't want custody responsibility. But you don't own actual Bitcoin—you own shares of a fund that holds Bitcoin. You can't send it to a wallet or use it for payments.
The Bottom Line
The cheapest way to buy Bitcoin in 2025 is through Kraken Pro using ACH deposits and limit orders. Total cost: just 0.16% ($1.60 per $1,000).
The key factors: use free ACH transfers (not cards), use the "Pro" trading interface (not the simple app), and place limit orders (not market orders). Following these three rules on any exchange will cut your costs by 50% or more.
