Are you encountering issues while buying or selling cryptocurrencies? Platforms like PancakeSwap and Uniswap occasionally display the "insufficient_output_amount" error, halting transactions. This guide explains the causes and provides actionable solutions to resolve the issue seamlessly.
Understanding the "Insufficient Output Amount" Error
This error typically arises due to low slippage tolerance or insufficient liquidity during transactions.
What Is Slippage?
Slippage refers to the difference between a token’s expected exchange value and the actual executed price. For example:
- You initiate a swap for 1 HERO using BNX tokens.
- Due to market fluctuations, you receive 0.9 HERO instead.
- Here, the slippage is 10%.
Causes of Slippage:
- Market Volatility: Rapid price changes between transaction initiation and completion.
- Low Liquidity: Limited token availability leads to price spikes.
Most platforms set default slippage tolerance below 1%, making transactions prone to failure. Adjusting this value mitigates the issue.
Fixing the Error on PancakeSwap
Method 1: Refresh the Page
- Simply reload PancakeSwap and retry the transaction.
Method 2: Incrementally Increase Slippage Tolerance
- Navigate to PancakeSwap.
- Select tokens in the "From" and "To" fields.
- Click Settings (gear icon).
- Under Slippage Tolerance, increase the value by 1% increments (e.g., 1.8% → 2.8%).
- Retry the transaction until successful.

Method 3: Set High Slippage (12–15%)
- Follow steps 1–3 above.
- Enter 12% or 15% in the slippage field.
- Ignore the "front-run" warning and proceed.
Note: Higher slippage may yield less favorable rates.
Fixing the Error on Uniswap
Method 1: Page Refresh
- Reload Uniswap and attempt the swap again.
Method 2: Gradual Slippage Adjustment

- Click the gear icon for settings.

Method 3: High Slippage (12–15%)
- Enter 12% or 15% in the slippage field.
- Confirm the swap.
