SEZL vs SLM: Which Is the Better Buy in 2026?
Last updated August 2026
Short answer
SEZL and SLM are similarly sized, but SLM trades noticeably cheaper on forward earnings (7.73x vs 23.66x): the market is paying up for SEZL's profile and pricing SLM more conservatively, or for faster growth. Which you prefer comes down to the drivers you believe, and whether adding either over-concentrates what you already own.
SEZL vs SLM: the tie-breaker metrics
Same yardstick, side by side (as of August 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.
| Metric | SEZL | SLM | What it tells you |
|---|---|---|---|
| Market cap | $5.20B | $4.89B | Size. The larger name is the incumbent; the smaller has more room to grow and more to prove. |
| Forward P/E | 23.66 | 7.73 | Valuation on next year's expected earnings, the same yardstick for both. Lower is cheaper for that growth; higher means the market is paying up. |
| Trailing P/E | 36.93 | 7.24 | Valuation on the last 12 months. A big drop from trailing to forward means the market expects earnings to jump, so more growth is already in the price. |
| Beta | 6.72 | 0.95 | Volatility vs the market. Above 1 swings harder than the index; below 1 is steadier. Higher beta means bigger drawdowns to hold through. |
| Price vs 52-week range | 72% of range | 53% of range | Where today's price sits between the 52-week low and high. Near the high is momentum with less margin of safety; near the low is out of favor or a discount, depending on why. |
Reading it: SLM is the cheaper of the two on forward earnings, but cheaper is not the same as better. Pair the valuation with growth (how far the forward P/E sits below the trailing P/E) and risk (beta) before you decide.
Before you buy: how SEZL and SLM affect your concentration
The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. SEZL and SLM share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.
This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined SEZL and SLM exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker.

What does Sezzle (SEZL) do?
Sezzle Inc. is a technology-enabled payments company operating mainly in the United States and Canada. Its platform lets shoppers split purchases into interest-free or low-cost installments at the point of sale (Pay-in-Four, Pay-in-Five, and Pay-in-Two options), while merchants pay Sezzle a fee for the added conversion and basket size. The company also earns from consumer subscriptions (Sezzle Premium and Anywhere), late and account fees, and interchange, and it reports both positive and negative payment activity to credit bureaus, a differentiator from many BNPL peers.
What does SLM Corporation (SLM) do?
SLM Corporation, known as Sallie Mae, is a consumer bank built around private education loans. It originates and holds Private Education Loans for students and families to cover the gap between college costs and federal aid and scholarships, and it funds those loans primarily through retail deposits at Sallie Mae Bank. It is the dominant player in US private student lending, holding roughly a 64 percent share of the market and originating about $7.4 billion of loans in 2025. Its business model leans on a wide net interest margin (around 5.3 percent), disciplined underwriting with high cosigner rates, and a heavy program of loan sales and share buybacks to return capital.
SEZL vs SLM: how do they differ?
Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.
- SEZL drivers: Subscriber and frequency growth; Profitable, self-funded scaling.
- SLM drivers: Dominant, high-margin niche lender; Capital return through buybacks and loan sales.
Which fits which kind of investor
A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: Sezzle lends to consumers, so a weaker economy or rising delinquencies could push credit losses back toward the 3 to 4 percent of GMV range and compress margins quickly. For SLM, sLM's fortunes are tied to consumer credit, so a weaker job market for graduates could push charge-offs and provisions higher and compress earnings.
SEZL or SLM: which should you pick?
SEZL vs SLM: the full fundamentals
SEZL. Sezzle is profitable and growing revenue near 30 percent, which is unusual among BNPL pure-plays. At a recent trailing P/E in the low 40s, the shares carry a growth premium, so the valuation leans heavily on Sezzle sustaining rapid subscriber and volume gains while keeping credit losses low.
SLM. SLM trades at a low earnings multiple (roughly high single digits on a forward basis) and around or below book value, which is typical for a specialty consumer lender the market views as credit-sensitive. Net interest income was about $375 million in the first quarter of 2026 on a net interest margin near 5.3 percent. Figures are approximate and drawn from the most recent reported results as of July 2026.
Headline figures (approximate, MAY 2026): SEZL shows revenue (q1 2026) ~$135.5M (up ~29% YoY), net income (q1 2026) ~$51.3M (~38% margin), gmv (q1 2026) ~$1.11B (up ~37% YoY), diluted eps (q1 2026) ~$1.47; SLM shows market cap ~$4B, revenue (ttm) ~$2B, q1 2026 eps (gaap diluted) ~$1.54, 2026 eps guidance ~$3.10 to $3.20.

FAQ
What is the difference between SEZL and SLM?
+
Sezzle Inc. SLM Corporation, known as Sallie Mae, is a consumer bank built around private education loans. They show up together because they share investment themes, but they are different businesses, so the better fit depends on which thesis you are expressing.
Is SEZL or SLM the better stock?
+
Neither is universally better; they suit different views and risk levels. Walnut is informational, not investment advice. Compare what each does, the tie-breaker metrics above, and the risks, then decide which fits your thesis and what you already own.
Which is cheaper, SEZL or SLM?
+
On forward P/E (as of August 2026), SEZL trades at 23.66x and SLM at 7.73x, so SLM is the cheaper of the two on next year's expected earnings. A lower multiple is not automatically the better buy: a richer valuation can be justified by faster growth, and a lower one can reflect real risk. Weigh the multiple against how fast each business is compounding.
Should you own both SEZL and SLM?
+
Because they share themes, owning both concentrates you in that theme. That can be intentional (a focused bet) or accidental (less diversification than it looks). Walnut can show your combined exposure across both, and whether adding either over-concentrates you, before you buy.
What are the risks of SEZL vs SLM?
+
SEZL: Sezzle lends to consumers, so a weaker economy or rising delinquencies could push credit losses back toward the 3 to 4 percent of GMV range and compress margins quickly. Competition is intense and well capitalized, from BNPL peers like Affirm, Klarna, Afterpay, and Zip to credit-card issuers and big tech (Apple, PayPal) folding pay-over-time into existing products, which can pressure merchant fees and user acquisition costs. Regulatory scrutiny is rising, including a US Senate inquiry letter to Sezzle in late 2025 and the UK FCA's BNPL regime taking effect in mid-2026, adding potential compliance costs. The stock has also drawn short-seller allegations (notably a 2024 Hindenburg report) about lending practices and disclosure, and at a P/E in the low 40s the shares price in continued rapid growth, leaving little room for disappointment. SLM: SLM's fortunes are tied to consumer credit, so a weaker job market for graduates could push charge-offs and provisions higher and compress earnings. Regulatory risk is real, as proposed CFPB rules on private loan servicing could raise compliance costs, and student lending draws political attention. The business is concentrated in a single loan product, leaving little diversification if private student loan demand softens or policy changes reshape the market. Competition from fintech refinancers such as SoFi, plus rate and funding-cost swings, can pressure margins and volumes. The low valuation reflects these overhangs rather than an obvious mispricing.
