The DeFi Lending Rate Comparison Calculator provides real-time comparison of supply (lending) and borrow rates across major DeFi protocols like Aave, Compound, and MakerDAO, helping users optimize yield or minimize borrowing costs.
공식
Net Lending APY = Supply APY + Reward Token APY - Gas Cost / Principal
- SA
- Supply APY (%) — Base interest rate earned by lenders
- BA
- Borrow APY (%) — Interest rate charged to borrowers
- RA
- Reward APY (%) — Additional yield from governance token incentives
- U
- Utilization (%) — Percentage of deposited assets currently borrowed
단계별 가이드
- 1Select the asset you want to lend or borrow (USDC, ETH, WBTC, etc.)
- 2Compare current supply rates and borrow rates across Aave V3, Compound V3, and others
- 3Factor in any additional governance token rewards (COMP, AAVE) that boost effective APY
- 4Account for gas costs on deposits, withdrawals, and reward claims to get net APY
풀어진 예시
입력
$50K USDC lending, Aave 4.2% supply + 0.3% AAVE rewards, Compound 3.8% supply + 0.5% COMP rewards
결과
Aave effective = 4.5%, Compound effective = 4.3% — Aave wins by 0.2% ($100/year on $50K)
입력
Borrowing 5 ETH, Aave borrow rate 2.8%, Compound 3.1%
결과
Aave saves 0.3% annually on the borrow = 0.015 ETH/year
피해야 할 일반적인 실수
- ✕Comparing raw supply rates without including reward token incentives
- ✕Not checking utilization rates — high utilization means rates will spike and you may not withdraw
- ✕Ignoring the difference between variable and stable borrow rates
자주 묻는 질문
Why do DeFi lending rates change constantly?
DeFi rates are algorithmically determined by supply and demand (utilization rate). When more people borrow, rates increase to attract more lenders. When borrowing decreases, rates drop. This happens in real-time, block by block.
Is DeFi lending safe?
Major protocols like Aave and Compound have billions in TVL and years of security track record, but risks remain: smart contract bugs, oracle manipulation, and liquidation cascades. Use only audited, battle-tested protocols.
