Slash Fee Calculator
Slash publishes two plans and six fees. The per-transaction numbers are small; the $25/month is the decision. This works out which plan is cheaper for the volume you actually send.

Free $0/mo · Pro $25/mo
Labels read Free / Pro. International wires cost the same on both plans, so they cannot change the verdict.
Monthly cost, side by side
Pro covers its cost at 25 same-day ACHs, 5 domestic wires or 5 FedNow payments a month, and saves money above that. Those are the only published prices it moves, so if most of your volume is international wires, the $25 buys you nothing.
- Stablecoin payments: Free swaps between USDSL, USDC and USDT; on/off-ramp fees described as "low" with volume discounts, no rate given.
- Global USD: No fee, FX spread or minimum published.
- Treasury: Yield is variable; the advertised figure assumes $500k+ in deposits. No fee schedule.
- Bill Pay: No pricing published.
- Invoicing: No pricing published; the FAQ asks the question and does not answer it.
- Working Capital: Underwritten per business. No public formula.
- Global Cards: No issuance or membership fee published. Platinum card notes only that "monthly membership fees may apply".
The published rate card, in full
Six fees sit on the two plan cards, and the comparison table underneath them carries a seventh. Pro zeroes three of the six and leaves the rest alone, which is what makes the upgrade decision a count rather than a rate.
The seventh is a one-off rather than a rail: a standard physical card costs $5, listed in the comparison table below the plan cards rather than on the cards themselves. Virtual cards stay unlimited and free on both plans, so the $5 only applies if you actually want plastic.
What the $25 actually buys
Slash Pro is unusually easy to evaluate because it moves three of the numbers on the plan card and none of the others. Same-day ACH goes from $1 to zero, domestic wires from $6 to zero, outgoing FedNow and RTP from $5 to zero. The international wire stays at $25 and the card foreign transaction fee stays at 1%. Slash also describes Pro as unlocking advanced, industry-specific capabilities, so the upgrade is not purely a fee change, but those three rows are the only published prices it touches.
So the question is a count, not a rate. 25 same-day ACHs a month, or 5 domestic wires, or 5 FedNow payments, and the subscription has covered its cost; every payment beyond that is a saving. A contractor paying a handful of suppliers is usually below that line; an agency running payroll and vendor payments through one account is well above it.

Assumptions and limits
Slash pricing: common questions
How much does Slash cost?
Slash publishes two plans: Free at $0/month and Pro at $25/month. On Free you pay $1 per same-day ACH, $6 per domestic wire and $5 per outgoing FedNow or RTP payment. Pro sets all three to $0. International wires are $25 on both plans, and the card foreign transaction fee is 1% with a $0.40 minimum on both. A standard physical card is $5 either way; virtual cards are unlimited and free.
Is Slash Pro worth $25 a month?
It depends on one thing only: how many domestic payments you send. Pro zeroes same-day ACH, domestic wires and FedNow and leaves every other published price alone, so it covers its cost at 25 same-day ACHs, 5 domestic wires or 5 FedNow payments a month, and saves money above that. Below that you are paying for a subscription you are not using; above it the saving grows with every payment.
What does Slash charge for a wire transfer?
A domestic wire is $6 on the Free plan and $0 on Pro. An international wire is $25 on both plans, and Pro does not discount it. Because the international fee is flat it is a heavy 5% on a $500 transfer and a negligible 0.05% on $50,000, which is the usual argument for batching cross-border payments rather than sending many small ones.
Does Slash charge a foreign transaction fee?
Yes, 1% with a $0.40 minimum on card spend in a non-USD currency, identical on both plans. The minimum is what bites on small purchases: a $5 charge abroad costs $0.40, an effective 8%. Above $40 the percentage takes over and the floor stops mattering.
What is the Slash instant deposit fee?
0.2% with a $50 maximum. The cap is generous: 0.2% only reaches $50 at $25,000, so any deposit above that is charged a flat $50 and the effective rate falls from there. On a $100,000 instant deposit the fee works out at 0.05%.
What does Slash charge for stablecoin payments?
Slash does not publish a rate. The stablecoin product page says swaps between USDSL, USDC and USDT are free and describes on/off-ramp fees as "low" with volume discounts, but names no number. We have deliberately left it out of the calculator rather than estimating. If stablecoin flow is central to your business, get the rate from Slash in writing before you model it.
Is Slash a bank?
No. Slash Financial, Inc. is a financial technology company, not an FDIC-insured bank. Its own disclosure names the bank: banking services are provided by Column N.A., Member FDIC, and deposits are insured through Column and the banks in Column’s sweep program. That structure is normal for US business banking platforms, but it is worth knowing where the insurance actually sits, because it flows through Column rather than through Slash.
Is the Slash card a credit card?
No, it is a charge card. The Slash Platinum Card is a Visa charge card issued by Column N.A., and Slash’s own footnote states that payment of the account balance is due in full daily. That is a meaningful difference from a business credit card with a monthly statement cycle: there is no float to speak of, so the card is a spend-management and cashback tool rather than a way to defer payment. Slash advertises cashback without publishing a rate, and the same footnote notes that monthly membership fees may apply.
Does Slash publish pricing for Treasury, Bill Pay or Invoicing?
No. Each has a product page and none carries a rate card; the FAQ lists the right questions without answering them. Treasury notes only that yields are variable and that the advertised figure assumes $500k+ in deposits. Those products are real, but their pricing is not public, so nothing on this page estimates them.
Opening a Slash account
The Free plan has no monthly cost, so the sensible order is to open on Free, watch a month of real payment volume, and upgrade only once the count crosses the breakeven.
