DeFi Calculator: Your Free Educational Tool for Mastering Decentralized Finance

in #defi3 days ago

Are you curious about DeFi but hesitant to invest real money before understanding the mechanics? Or perhaps you're an experienced crypto investor looking to simulate different strategies before committing capital? Look no further — DeFi Calculator is here to help you navigate the complex world of decentralized finance with confidence.

Best of all? It's completely free, and you don't need to create an account. Just visit https://calculadoradefi.vercel.app and start exploring.

What is DeFi Calculator?

DeFi Calculator is an interactive web application designed to simulate various DeFi operations, allowing you to understand the potential risks and rewards before making real financial decisions. Built with modern web technologies (React, TypeScript, and Vite), this educational tool provides accurate calculations, interactive visualizations, and scenario analysis — all in a clean, intuitive interface.

Whether you're a complete beginner trying to grasp DeFi concepts or a seasoned trader planning your next move, this tool has something for everyone.

🎯 Key Features

1. Liquidity Pool Simulator

Ever wondered how liquidity providers make money in AMM (Automated Market Maker) protocols like Uniswap or PancakeSwap? This simulator gives you a complete understanding of the mechanics.

What you can do:

  • Configure custom token pairs (ETH/USDC, BTC/USDT, or any combination you choose)
  • Set pool parameters: token amounts, current prices, and fee tiers (0.01%, 0.05%, 0.3%, or 1%)
  • Calculate automatically: LP tokens received and total pool value in USD
  • Project earnings: See estimated returns per minute, hour, day, week, month, and year
  • Understand APR: Calculate Annual Percentage Rate based on daily volume and pool fees

The game-changer? Impermanent Loss analysis.

The simulator includes 7 pre-configured price scenarios that show you exactly what happens when token prices change:

  • Bear market scenarios (prices drop 50%, 30%, 20%)
  • Neutral scenario (prices stay the same)
  • Bull market scenarios (prices rise 20%, 30%, 50%)

For each scenario, you'll see:

  • The dreaded Impermanent Loss (IL) calculation
  • Fee earnings accumulated during the period
  • Net result: fees minus IL
  • Whether you're actually making money or losing value

Visualizations include:

  • Interactive charts showing earnings projections over time
  • Comparative graphs displaying all scenarios side by side
  • Detailed tables breaking down every metric

This feature alone can save you thousands of dollars by helping you understand when providing liquidity makes sense and when it doesn't.

2. Leveraged Trading Simulator

Leverage can multiply your gains — or your losses. Before risking real capital, simulate your leveraged positions with precise calculations.

Configure your position:

  • Collateral setup: Choose your collateral asset (USDT, USDC, DAI, etc.), amount, interest rate, and current price
  • Loan configuration: Select the asset to borrow (ETH, BTC, etc.), quantity, interest rate, and current price
  • Risk parameters: Set liquidation threshold, position duration (in days), and expected price change

Critical metrics calculated:

  • Health Factor (HF) — the single most important metric in leveraged trading:

    • 🟢 Low Risk: HF > 2.0 (safe zone)
    • 🟡 Medium Risk: HF 1.5-2.0 (caution advised)
    • 🟠 High Risk: HF 1.1-1.5 (dangerous territory)
    • 🔴 Critical Risk: HF < 1.1 (liquidation imminent)
    • ⚠️ Liquidation: HF < 1.0 (position closed by protocol)
  • Liquidation price: The exact price at which your position gets liquidated

  • Total cost: Interest on both collateral and borrowed assets

  • Net Profit/Loss: Your bottom line after all costs

  • ROI: Return on Investment percentage

Scenario analysis:

Test multiple price movements (bull and bear markets) to see how your position performs under different conditions. The simulator shows you exactly when you profit, when you lose, and when you get liquidated.

Visual aids:

  • Profit & Loss charts across different price variations
  • Color-coded risk indicators
  • Comparative tables for easy decision-making

This simulator teaches you the fundamentals of margin trading, risk management, and the importance of monitoring your health factor — lessons that could save you from liquidation in real trading.

3. Liquidity Pool Gains Projection

Plan your DeFi portfolio with precision using this advanced projection tool.

Features:

  • Manage multiple pools: Add as many liquidity pools as you want with individual parameters
  • Customizable inputs: Pool name, invested amount (USD), yield rate, and yield type (APR or APY)
  • Automatic calculations: Returns calculated for multiple time periods (minute, hour, day, week, month, year)
  • Individual & aggregated results: See performance per pool and combined totals
  • Visual comparisons: Interactive charts comparing returns across different pools and timeframes
  • Top performers: Automatic identification of your most profitable pools
  • Smart insights: Summary with key metrics like total invested, expected return, and ROI
  • Data persistence: Your pools are saved locally, so you don't lose your work
  • Import/Export: Back up your data or share configurations with others

This tool is perfect for DeFi portfolio management, allowing you to compare different liquidity provision strategies and optimize your capital allocation.

4. Yield Calculator (Coming Soon)

An advanced calculator for projecting yields across different DeFi protocols, with features like:

  • APY (Annual Percentage Yield) calculations
  • Protocol comparisons
  • Compound interest analysis
  • Auto-compounding simulations

Stay tuned for this powerful addition to the toolkit!

📊 Real-World Example

Let's walk through a quick example using the Liquidity Pool Simulator:

Scenario: You want to provide liquidity to an ETH/USDC pool on Uniswap.

  1. Input: 10 ETH at $2,000 each ($20,000 total)
  2. Input: 20,000 USDC at $1 each ($20,000 total)
  3. Select: 0.3% fee tier
  4. Estimate: $500,000 daily volume

Results:

  • Total pool value: $40,000
  • Daily earnings: $500,000 × 0.3% = $1,500
  • Your share (if you own 1% of pool): $15/day
  • Projected APR: ~13.69%

But wait — what if ETH price increases 20%?

  • Impermanent Loss: ~0.6%
  • Fee earnings over 30 days: ~$450
  • Net result: Positive (fees outweigh IL)

The simulator shows you all of this instantly, helping you decide if the position is worth it.
