SoFi's bank charter drives deposits to $40.2 billion in four years

SoFi's 2022 bank charter turned a funding disadvantage into a $40.2 billion deposit machine, reshaping the fintech lender's cost structure and profit trajectory.

SoFi Technologies' deposit base ballooned to $40.2 billion as of March 31, 2026, up from $1.2 billion exactly four years earlier, after the company secured a national bank charter through its acquisition of Golden Pacific Bancorp in February 2022. The low-cost funding source propelled net interest income to $2.2 billion in 2025, a 781% increase from $252 million in 2021.

"Deposits are considered extremely sticky, as they establish a bank's direct relationship with where customers park their money," the company said in its latest filings. SoFi's savings account pays a standard annual percentage yield of 3.1 percent, well above the national average, which has helped attract and retain capital.

Deposits now represent 94 percent of SoFi's $42.9 billion in total liabilities, compared with just 17 percent four years ago. The shift supported a net interest margin of 5.94 percent in the first quarter of 2026, a level that rivals traditional banks with decades-old branch networks.

Before obtaining the charter, SoFi relied on securitized debt, warehouse facilities and convertible notes to fund its lending operations — sources that are both more expensive and dependent on favorable capital market conditions. The charter eliminated that structural disadvantage, giving SoFi a cost of funding that competes with incumbent banks while maintaining a digital-only operating model with no branch overhead.

Deposit Growth Reshapes the Funding Base

SoFi received approval from the Office of the Comptroller of the Currency and the Federal Reserve in January 2022 to acquire Golden Pacific Bancorp, a community bank based in Sacramento, California. The deal closed the following month, and SoFi immediately began offering checking and savings accounts to its members.

The rapid deposit accumulation signals strong demand for a tech-enabled banking platform, the company said. Unlike peer fintech lenders that still depend on warehouse lines or loan sales to fund originations, SoFi now operates with a deposit-funded balance sheet similar to JPMorgan Chase or Bank of America — but without the physical branch costs those institutions carry.

Earnings Trajectory and Investor Implications

Management expects adjusted earnings per share to increase at a compound annual rate of 40 percent at the midpoint over the next three years. That growth trajectory, supported by the low-cost deposit base and expanding net interest margin, positions SoFi differently from most fintech companies, which typically trade on user growth rather than profitability.

SoFi shares trade on the Nasdaq under the ticker SOFI. The company's ability to sustain deposit growth while maintaining net interest margins above 5 percent will determine whether it can deliver on that earnings forecast. Traditional banks with comparable margins, such as regional lenders, typically trade at 10 to 12 times forward earnings — a valuation multiple that would represent a significant premium to SoFi's current level if the company executes on its guidance.
