ACH bank transfers are the cheapest way to move fiat into crypto, avoiding the 3-5% credit card fees most on-ramps charge. We compared Coinbase, MoonPay, Transak, and Simplex on ACH availability, fees, and speed. Coinbase wins for low fees and regulatory trust, while MoonPay leads for direct-to-wallet convenience.
Buying crypto with a credit card is convenient — but you're paying 3-5% extra for that convenience. ACH bank transfers (direct from your checking account) are the cheapest way to fund a crypto purchase, often costing 1% or less.
The catch? Not every on-ramp supports ACH. Some are built for card-only transactions. Here's a clear ranking of the best crypto on-ramps that accept ACH bank transfers, based on cost, speed, and ease of use.
| Product | ACH Fee (est.) | ACH Speed | Best For |
|---|---|---|---|
| Coinbase | ~1.5% | 1-3 days | Low fees + full exchange |
| MoonPay | ~3-4% | 1-2 days | Direct-to-wallet widgets |
| Transak | ~2-3% | 1-3 days | DeFi wallet integrations |
| Simplex | ~3-5% | 2-4 days | Global coverage |
Coinbase is the gold standard for ACH transfers in the US. It's a fully regulated exchange, not just a payment widget, which means you get a full trading platform alongside your on-ramp.
Why it wins: Coinbase charges roughly 1.5% for ACH purchases — significantly less than the 3.74% it charges for debit/credit card buys.3 You can deposit via ACH with no fee at all and then trade on the exchange, effectively bypassing on-ramp fees entirely.
Trade-off: You need to create an account and complete KYC (usually a few minutes). Funds settle in 1-3 business days before you can withdraw to an external wallet.
Best for: Anyone who wants the lowest fees and doesn't mind using a full exchange.
MoonPay is the most popular embedded on-ramp widget. You'll find it inside MetaMask, Ledger Live, and hundreds of other wallets. It supports ACH bank transfers in the US through its MoonPay Balance feature.
Why it ranks high: MoonPay prioritizes speed and simplicity.2 You can buy crypto and have it sent directly to your self-custody wallet without touching a centralized exchange. The UX is polished — enter an amount, pick your bank, confirm.
Trade-off: Fees are higher. For a $200 purchase, MoonPay takes around 7%.3 ACH is available but the fee spread is wider than Coinbase.
Best for: Wallet-first users who want crypto delivered directly to their address.
Transak is a direct competitor to MoonPay, commonly found in DeFi wallets and dApps. It supports ACH transfers in the US and offers competitive rates compared to card-only alternatives.
Why it's a solid pick: Transak supports bank transfers across multiple regions and integrates with 100+ wallets and apps. It also offers a "one-click buy" flow for returning users.
Trade-off: ACH availability varies by state and bank. Fees hover around 2-3%, which is better than MoonPay but higher than Coinbase.
Best for: DeFi users who want an embedded on-ramp without leaving their wallet.
Simplex is one of the oldest on-ramp providers and is known for its fraud-protection guarantee. It supports ACH in the US and has a wide global footprint.
Why it's included: Simplex is accepted by many exchanges and wallets as a payment processor. It offers a "no chargebacks" guarantee, which merchants appreciate.
Trade-off: ACH support is less emphasized than card payments. Fees can be higher (3-5%) and settlement times longer.
Best for: Users outside the US who still want bank-transfer support.
The biggest decision when choosing an ACH on-ramp is whether to use a full exchange (like Coinbase) or a direct-to-wallet widget (like MoonPay or Transak).
Full exchange route:
Total cost: ~1.5% + withdrawal fee. Best for larger purchases.
Direct-to-wallet route:
Total cost: ~3-7% all-in. Best for smaller, quick purchases.
Credit card purchases at on-ramps typically incur a 3-5% "convenience fee" passed through from Visa/Mastercard. ACH bypasses that entirely. For a $1,000 purchase, that's $30-50 saved.
The trade-off is speed: ACH takes 1-3 business days to clear, while credit cards are instant. If you need crypto immediately, a card might be worth the premium. If you're planning ahead, ACH is the smarter play.
