Crypto loan rates can range from 0% (Sovryn Zero) to 12% (some retail platforms at high LTV) for what looks like the same product. The variation is not arbitrary. Five specific inputs drive every quote, and once you understand them you can compare any two lenders apples-to-apples and predict where the rate will land before you even apply.
Variable vs fixed: the structural divide
Every crypto loan is either variable-rate or fixed-rate, and the distinction matters more than the headline number.
Fixed-rate loans are typical of CeFi platforms — Ledn, Nexo, APX, Unchained. You sign at a specific rate, and that rate holds for the entire loan term. Predictable, but you cannot benefit from rate drops.
Variable-rate loans are the standard on DeFi protocols — Aave, Compound, Spark. The rate is computed algorithmically based on the protocol’s utilization rate, recalculating in real time. We covered the protocol mechanics in Top 5 DeFi Lending Protocols.
The five inputs that drive every rate
1. Loan-to-Value (LTV). The single biggest driver. Lower LTV means lower risk to the lender, which means lower rate. We walked through the LTV math in How to Calculate Your Crypto Loan LTV.
2. Term length. Shorter terms get lower rates on most platforms because the lender has less duration risk. A 3-month fixed loan typically prices 100-200 basis points below a 12-month loan at the same LTV.
3. Collateral asset. BTC and stablecoin collateral get the lowest rates because they are the most liquid. ETH is close behind. Lower-cap assets get worse rates.
4. Lender risk premium. Different lenders price risk differently based on their internal cost of capital, regulatory overhead, and target margin.
5. Market conditions. Macro interest rates matter. When the Fed funds rate is high, crypto loan rates drift up because lenders’ cost of capital rises.
How DeFi utilization curves actually work
For any DeFi pool, the rate is a function of utilization. The standard model has two regimes:
Below the kink. Up to ~80% utilization, rates rise linearly and gently. A pool at 50% utilization might charge 4% APR; at 75% utilization, 6% APR.
Above the kink. Above 80% utilization, rates rise much more steeply. A pool at 90% utilization might charge 25% APR. We covered protocol-level mechanics in DeFi vs CeFi Lending 2026.
APR vs APY: don’t get confused
For loans, the standard metric is APR — your effective annual interest cost without compounding. Compare APRs across lenders.
APY includes compounding effects and is typically used for yield products. The number to demand for any loan comparison is APR with all fees included.
Why Nexo at 1.9% is not Aave at 5%
- Nexo 1.9% requires: top-tier loyalty status, LTV under 20%, fixed-term commitment.
- Aave 5%: any LTV up to the protocol limit, no token requirement, variable rate that can rise.
For an apples-to-apples comparison, you have to match LTV bucket, term, and platform requirements.
Practical rate-shopping framework
- Decide your LTV target (lower is better; under 40% is conservative).
- List 5 lenders that cover your collateral asset.
- For each, find the rate for your specific LTV and term combination.
- Add origination fees, withdrawal fees, and any account requirements.
- Compute effective APR including all fees.
Frequently asked questions
Why are crypto loan rates so much lower than personal loan rates?
Because crypto loans are over-collateralized — you put up more collateral than the loan amount. Personal loans have no collateral, so the lender prices in default risk.
What is the difference between APR and APY on a crypto loan?
APR is the annual percentage rate without compounding. APY includes compounding. For loans, APR is the standard.
Can I negotiate a crypto loan rate?
On retail CeFi platforms, the rate is typically tier-based. For loans above $100K-$500K, some lenders open relationship-pricing discussions.
Why do DeFi rates change every block?
DeFi rates are governed by a utilization curve. As more borrowers tap the pool, the rate algorithm increases the rate to incentivize new deposits.
Why is Nexo as low as 1.9 percent while Aave shows 5 to 8 percent?
Nexo offers 1.9 percent only to top-tier loyalty members at very low LTV. Aave rates apply broadly without tier requirements.
