Picking how to restructure a five- or six-figure pile of student debt isn’t something you want to rush. And in 2026, with interest rates bouncing around and the federal repayment system having gone through its biggest overhaul in years, getting this decision right can genuinely mean tens of thousands of dollars in your pocket — or not — over the life of your loan.
Here’s the thing, though: refinancing isn’t a one-size-fits-all marketplace. The three names that keep coming up — SoFi, Earnest, and Splash Financial — aren’t just competitors offering slightly different rates. They’re built on completely different models. SoFi operates like a full-blown digital bank with a massive ecosystem wrapped around it. Earnest runs on an algorithm that cares more about your cash flow habits than your credit score. And Splash Financial doesn’t lend you money at all — it shops your application around to a network of credit unions and community banks behind the scenes.
This guide breaks down how each one actually works, what they’ll really cost you, and which one fits which kind of borrower.
First, Understand the Plumbing: Direct Lenders vs. Marketplaces
Before we get into rates and numbers, it helps to understand what’s actually happening when you hit “submit” on each platform.

Same Brand Same/Partner of Credit Unions Bank or Credit Union
(e.g. MOHELA) & Community Banks (Terms vary by match)With a direct lender — SoFi or Earnest — you’re dealing with one company from start to finish. They approve you, they fund the loan, and they (or a closely tied partner like MOHELA) service it afterward. The upside here is consistency: one app, one dashboard, one set of policies you can actually learn.
With a marketplace like Splash Financial, things work differently. Splash doesn’t have its own pile of cash to lend you. Instead, it takes your information and quietly shops it to a network of smaller credit unions, regional banks, and institutional investors. Why does that matter? Because a small credit union somewhere in Ohio with extra capital sitting around might offer a rate that a giant like SoFi simply wouldn’t bother matching. Competition between lenders works in your favor here.
SoFi: The All-in-One Ecosystem for High Earners
SoFi has been around long enough that it doesn’t really think of itself as a “student loan company” anymore. With a full banking charter under its belt, it’s positioned itself as more of a complete financial hub for people already doing pretty well — or expecting to soon.
Who Gets Approved
SoFi doesn’t publish a hard credit score cutoff, but let’s be honest about what the data shows: if you’re under 700, your odds drop fast unless you’ve got a cosigner with serious financial standing. They also want to see stable income — either an existing job or a signed offer letter starting within 90 days.
The Numbers (2026)
- Fixed APR Range: 3.99% – 9.99% (this already factors in the 0.25% autopay discount and an extra 0.125% off if you’re a SoFi Plus member with direct deposit)
- Variable APR Range: 5.74% – 9.99%, tied to the 30-day SOFR
- Repayment Terms: Fixed options only — 5, 7, 10, 15, or 20 years
- Fees: None. No origination fee, no prepayment penalty.
What You’re Really Paying For: The Perks
Here’s where SoFi makes its case, even if the rate isn’t the absolute lowest on paper. Refinance with them and you unlock:
Free access to a Certified Financial Planner. Not a one-time call — ongoing, unlimited consultations as part of being a member.
Genuinely solid unemployment protection. Lose your job through no fault of your own, and SoFi will pause your principal and interest payments in three-month chunks, up to a full year total. While that’s happening, their career team actually helps — resume reviews, interview prep, the whole thing.
Reward points that pay down your loan. Use their checking, savings, or investing products, and the points you rack up can go straight toward extra principal payments on your student loan.
The Honest Pros and Cons
What’s good: the perks are genuinely valuable, the app ties everything together nicely, the unemployment protection is one of the best in the industry, and they lend nationwide.
What’s not: your term options are limited to those five fixed lengths, the credit and income bar is high, and if you needed a cosigner to get approved, there’s no path to release them later.
Earnest: Built for People Who Actually Budget
Earnest’s whole pitch from day one has been that your credit score is a lagging indicator — it tells you where you’ve been, not where you’re going. So instead, they dig into how you actually manage money day to day.
Who Gets Approved
This is where Earnest opens the door wider — they’ll work with credit scores as low as 650, which puts them within reach for a lot of recent grads who haven’t built up a long credit history yet. But don’t mistake “lower score requirement” for “easy.” Their algorithm looks at your savings cushion, whether you’re regularly overdrafting your accounts, and whether your income comfortably clears your fixed monthly costs.
The Numbers (2026)
- Fixed APR Range: 3.95% – 9.99% (includes the 0.25% autopay discount; if you’ve got an advanced degree and a balance over $100k, you might unlock rates as low as 3.52%)
- Variable APR Range: 5.88% – 10.24%, with caps that depend on your term — 8.95% for terms of 10 years or less, 9.95% for 11-15 years, and 11.95% beyond that
- Repayment Terms: This is the big one — up to 180 different month-by-month options between 5 and 20 years
New for 2026: Refinancing Before You Even Graduate
As of this year, Earnest rolled out something genuinely useful for students who’ve already landed a job. If you’ve got a signed offer letter for a position starting after graduation, you can refinance up to six months before you actually finish school. On top of that, they’ll honor your existing grace period for up to nine months — meaning you can lock in today’s rate before you’ve even started your first paycheck.
“Precision Pricing” — Their Signature Move
Most lenders make you pick from a handful of standard term lengths — 5 years, 10 years, 15 years, and so on. Earnest flips that around. Know that you can comfortably afford exactly $435.50 a month? Type that number in, and their system will calculate the exact term — say, 11 years and 4 months — that gets you there while minimizing how much interest you pay overall.
The Honest Pros and Cons
What’s good: the term flexibility is unmatched anywhere else, the 650 credit floor opens doors for newer grads, you can skip one payment per year without penalty, and the pre-graduation refinancing option is genuinely rare in this space.
What’s not: there’s no cosigner release option here either, and variable rate loans simply aren’t available if you live in Alaska, Illinois, Minnesota, Mississippi, New Hampshire, Ohio, Tennessee, or Texas.
Splash Financial: The Marketplace With a Medical Specialty
Splash plays a different game entirely. By routing your application through a network of regional banks and credit unions — institutions that don’t have the marketing budgets of SoFi or Earnest — Splash can sometimes surface rates that simply aren’t available anywhere else.
Who Gets Approved
Since your application gets passed along to different lenders, the exact requirements shift depending on the match. But generally, you’ll have the best luck with a credit score around 700 or higher and a debt-to-income ratio that stays under 30%. U.S. citizens and permanent residents are eligible.
The Numbers (2026)
- Fixed APR Range: 4.24% – 10.49% (varies a lot depending on which credit union or bank you get matched with)
- Variable APR Range: 4.74% – 10.49% — and interestingly, the starting point here is often lower than what direct lenders offer, thanks to those local credit unions having cheaper capital to work with
- Repayment Terms: 5, 7, 8, 10, 12, 15, 20, or 25 years
- Funding Limits: None. Splash can handle even very large balances.
Where Splash Really Shines: Medical Residents
If there’s one thing Splash does better than anyone else, it’s this. Medical residents, fellows, and dental practitioners — people carrying enormous six-figure debt loads while earning resident-level salaries — get access to a program that lets them refinance their full balance and pay just $100 a month for the entire length of their residency or fellowship, plus up to six months after they start practicing. Interest still builds during this time, but critically, it doesn’t compound — so you’re not getting hit with interest-on-interest while you’re barely making minimum wage as a resident.
The Honest Pros and Cons
What’s good: one soft credit check gets you access to local credit union rates you’d never find on your own, the cash-back sign-up bonuses can hit $1,000 for larger balances, and the medical residency program is honestly one of the best deals in the industry for that specific group.
What’s not: your experience really depends on which lender you get matched with — terms, customer service, everything can vary. Cosigner release depends entirely on that match too, and sometimes you’ll be required to actually join a credit union to get the loan.
The Real Numbers: What Refinancing Actually Saves You
Let’s make this concrete. Say you’ve got $100,000 in private student debt, 10 years (120 months) left to pay it off, and you’re currently locked into a 7.50% rate.
Using the standard amortization formula:
M=P(1+r)ⁿ−1r(1+r)ⁿ
Where P = $100,000, r = 0.075/12 = 0.00625 monthly, and n = 120 payments — your current monthly payment comes out to $1,187.02. Over the full term, that’s $142,442.14 total, with $42,442.14 of that being pure interest.
Now here’s what happens if you refinance at today’s rates:
| Metric | Current Loan | SoFi / Splash (5.32% Fixed) | Earnest (4.95% Fixed) |
|---|---|---|---|
| Remaining Principal | $100,000 | $100,000 | $100,000 |
| Fixed APR | 7.50% | 5.32% | 4.95% |
| New Monthly Payment | $1,187.02 | $1,076.43 | $1,058.20 |
| Monthly Savings | — | +$110.59/mo | +$128.82/mo |
| Total Lifetime Interest | $42,442.14 | $29,171.60 | $26,984.00 |
| Total Net Savings | — | $13,270.54 | $15,458.14 |
Even the more “modest” rate cut here saves over $13,000 across the loan’s life. Not pocket change.

| Refinance Before Graduation | No | Yes (up to 6 months early) | No |
So Which One Is Right for You?
If you’re a high earner who values extras over a marginally better rate — go with SoFi. The CFP access and unemployment safety net alone can be worth more than a fraction of a percentage point in interest, especially if you’re the type who’ll actually use those benefits.
If you live and die by your budget spreadsheet — go with Earnest. Being able to dial in your exact monthly payment and have the term calculated around it is something no other lender offers. It’s also your best bet if your credit is still in the 650-690 range, or if you’ve got a job offer in hand and want to lock in a rate before you even walk across the graduation stage.
If you’re a medical resident, or you just want to see what local credit unions are offering without a dozen hard inquiries — go with Splash. The $100/month residency program is hard to overstate in terms of value, and even outside of medicine, Splash is good at surfacing rates you wouldn’t find searching on your own.
Quick Answers to the Questions Everyone Asks
Can I refinance federal loans with these companies? Yes — but think hard before you do. The moment you refinance federal debt into a private loan, it’s private for good. That means no more PSLF, no income-driven repayment plans, no federal safety nets of any kind. If there’s any chance you’ll need those down the road, don’t do this.
Will checking my rate hurt my credit? No. All three platforms start with a soft credit pull, which doesn’t affect your score at all. A hard pull only happens once you actually pick an offer and submit a full application.
Are there hidden fees — application fees, prepayment penalties, anything like that? Nope. All three are completely free of those. Pay your loan off in two years if you want, with zero penalty.
Can I refinance more than once? Yes, as many times as you want. If rates drop again next year after you refinance now, there’s nothing stopping you from doing it again to grab the better deal.
