How Does Block Make its Money?
Block, Inc. (formerly Square) operates two main ecosystems: Square — a payment processing and business management platform for merchants — and Cash App — a consumer finance app for peer-to-peer payments, banking, investing, and Bitcoin. The company also owns a majority stake in the buy-now-pay-later platform Afterpay (now integrated into both ecosystems) and operates TIDAL, a music streaming service, and TBD, a Bitcoin-focused open developer platform.
Revenue Breakdown
| Segment | 2024 | 2023 | YoY Growth |
|---|---|---|---|
| Cash App | $15.18B | $12.65B | +20.0% |
| Square | $7.48B | $7.06B | +5.9% |
| Blockchain (TIDAL, TBD) | $0.34B | $0.30B | +13.3% |
| Total Net Revenue | $24.12B | $21.92B | +10.0% |
Important note on Bitcoin revenue: Block reports Bitcoin sales through Cash App as revenue, with the Bitcoin purchase cost recorded separately. This inflates the top-line significantly. Gross profit is a much better measure of Block’s actual economics.

Cash App — 58% of Gross Profit
Cash App has 57 million monthly active users and generates revenue from:
- Bitcoin trading: Users buy and sell Bitcoin within Cash App. Block earns a spread (~2%) on each transaction. Bitcoin revenue was ~$11B in 2024, but gross profit was only ~$0.37B (thin margin).
- Cash App inflows (peer-to-peer): Free P2P transfers drive user acquisition. Monetization comes from:
- Cash App Card: A Visa debit card linked to Cash App balances. Block earns interchange fees when users spend.
- Instant deposit fees: Users can instantly transfer Cash App funds to their bank for a small fee (~1.5%).
- Cash App Borrow: Small personal loans ($20-$200) with flat fees.
- Afterpay/BNPL: Integrated buy-now-pay-later at checkout, earning merchant fees.
Square — 38% of Gross Profit
Square provides merchants with payment hardware and software:
- Payment processing: Square takes ~2.6% + $0.10 per swipe/tap transaction. Payment processing generates the bulk of Square revenue.
- Software subscriptions: Restaurants (Square for Restaurants), retail (Square for Retail), and appointments-based businesses pay monthly SaaS fees for point-of-sale software.
- Square Banking: Business loans and savings accounts for Square sellers.
- Hardware: Square Terminal, Square Register, and Square Reader — sold near cost as an on-ramp to the payments ecosystem.

Key Financial Metrics
- Gross Margin: 36.9% — Low because Bitcoin pass-through revenue inflates the denominator. On a gross-profit basis, which excludes Bitcoin cost, margins are much healthier.
- Operating Margin: 6.9% — Block has been steadily improving operating efficiency under its “Rule of 40” framework, targeting gross profit growth rate + operating margin ≥ 40.
- Gross Profit Growth: +18.5% — The most important metric for evaluating Block. Gross profit strips out Bitcoin pass-through and reveals the underlying business growth.
- Cash App Gross Profit per User: ~$90/year — Up from ~$72 in 2023, showing improving monetization of the user base.
Where Does Block Spend its Money?
- Bitcoin Purchases (~$11B): Buying Bitcoin to fulfill customer orders on Cash App. This is a pass-through cost, not a true operating expense.
- Product Development (~$2.9B): Engineering for Cash App, Square, Afterpay integration, and Bitcoin/blockchain projects.
- Sales & Marketing (~$1.4B): Cash App acquisition (referral bonuses, brand campaigns), Square seller outreach.
- G&A (~$1.5B): Legal, compliance, and corporate overhead. Block has ~13,000 employees after a 2023 workforce reduction.
- Transaction & Loan Losses (~$0.5B): Chargebacks, fraud, and defaults on Cash App Borrow and Square Loans.
What to Watch
- Cash App monetization — Growing gross profit per user from $90 to $120+ would validate the financial super-app thesis. The Cash App Card, Borrow, and Afterpay are the key levers.
- Square seller growth — Square is growing slowly (~6%) and facing competition from Clover (Fiserv), Toast, and Shopify Point of Sale. Reaccelerating Square growth is a management priority.
- Bitcoin strategy — Block holds 8,211 Bitcoin on its corporate balance sheet (~$800M+). The company also invests in Bitcoin mining hardware. The strategic commitment to Bitcoin carries both upside and reputational risk.
- Afterpay integration — Block paid $29B for Afterpay in 2022 (widely considered an overpay). Integration into Cash App and Square is progressing, but BNPL competition from Klarna and Apple is intense.
- Operating leverage — Block’s 2024 operating income more than doubled. If the company can sustain 15%+ gross profit growth while holding expenses roughly flat, margin expansion should accelerate.
