A
loan on Aave grows every block as interest accrues. Repaying sends
back to Aave, which burns the matching amount of your debt. Pay part of it and your health factor rises; pay all of it and your collateral is free to withdraw. There is no penalty for repaying early and no minimum term.

Before You Repay

  • Have the USDC in your wallet. You repay from your wallet's balance, and a full repayment needs a little more than you borrowed, because interest has been accruing since.
  • Know what "all" means. Your debt keeps growing between the moment you look and the moment the transaction lands. Typing the number you saw can leave a few cents of debt behind. Repaying "all" instead tells Aave to clear whatever is owed in the block the repayment lands in.
  • Repaying doesn't return your collateral. Your supplied
    or other collateral stays on Aave until you withdraw it, which is a separate step.

Repaying By Hand

  1. Open Aave's app, connect your wallet and switch to the Base market.
  2. Find
    under Your borrows and choose Repay.
  3. Pick the maximum to clear the whole debt, or enter part of it.
  4. Approve
    for Aave, or sign the permit the app asks for, then confirm the repayment.

Repay With Plug

Use in App
The plug does one thing: it repays all of your
debt on the Aave Base market. "All" is worked out when the run lands, so it covers every bit of interest up to that block and leaves no dust behind. The approval happens inside the same run.
To pay down part of the loan instead, change "all" to an amount. The plug reads the wallet that runs it, so it works for whoever opens it. We simulated it as a real Base borrower holding enough
, and it cleared the whole loan in one run.

What It Costs

Aave charges nothing to repay beyond the interest already owed. In November 2026
borrowed on Aave's Base market cost 6.50 percent a year, variable, so every day the loan stays open adds about 0.018 percent of it.
Gas for the run was about 740,000, roughly a cent at Base's gas prices.
