Measuring Real APY vs Incentive APY in Mixed Vault Portfolios

By Alex Assoune Jan 16, 2026

When building a passive income portfolio using stablecoins and LP tokens in yield aggregators, it’s easy to get distracted by high APY numbers. Many vaults advertise double-digit yields, but the reality can be very different once you understand real APY vs incentive APY.

This guide will help you decode the numbers, measure real returns, and optimize your mixed vault portfolio for consistent passive income.

What Is APY?

APY (Annual Percentage Yield) represents the return you can earn over a year, assuming rewards are reinvested.

Simple APY: Just the interest rate without compounding
Compound APY: Includes reinvested rewards, showing the full effect of compounding

In crypto yield aggregators, APY can come from multiple sources—some sustainable, some temporary.

Real APY vs Incentive APY

1. Real APY

Comes from actual yield-generating activity:
- Lending interest
- Trading fees from AMMs
- Liquid staking rewards
Usually more stable and sustainable
Example: USDC vault earning 8% from lending interest → Real APY = 8%

2. Incentive APY

Comes from reward tokens distributed by protocols
Often temporary and may decrease as incentives are diluted
Can make APY look much higher than what is sustainable
Example: LP vault gives 10% from fees + 15% in reward tokens → Advertised APY = 25%
But the real yield depends on token market value, which can fluctuate

Why Differentiating APY Matters

Avoid Overestimating Returns
High APY from incentives can collapse quickly, leaving your portfolio underperforming.
Risk Management
Incentive-heavy vaults often involve LP tokens or volatile assets, increasing risk.
Tax Planning
Incentive tokens may be taxable upon receipt, affecting net returns.

Step 1: Identify Sources of APY in Your Vaults

Check your aggregator dashboard for:

Breakdown of interest vs token rewards
Compounding frequency
Historical performance charts

Example: Tulip Protocol dashboard (tulip.garden) shows LP vaults with:

7% stablecoin yield
12% incentive token yield

Step 2: Convert Incentive Tokens to Real Yield

Estimate the USD value of your reward tokens
Factor in token price volatility
Deduct any swap fees if reinvesting

Formula for real APY from incentives:

Real Incentive APY = (Reward Token USD Value / Deposit USD Value) * 100

Example:

Deposit: $5,000
Rewards: 50 REWARD tokens valued at $10 each → $500
Real Incentive APY = $500 / $5,000 * 100 = 10%

Step 3: Combine Stablecoin and LP Vault APYs

If you have a mixed portfolio:

Asset	Allocation	Real APY	Weighted Yield
USDC Vault	50%	8%	4%
SOL/USDC LP Vault	50%	12%	6%
Portfolio APY	100%	—	10%

Weighted yield = allocation % × real APY of each asset

This gives a realistic estimate of your portfolio’s passive income.

Step 4: Monitor APY Over Time

Incentive APY is dynamic; it may decline as token emissions reduce
Real APY may fluctuate with LP fees or lending rates
Use portfolio trackers like Zerion or Debank

Tip: Check monthly or weekly to rebalance between stable and LP assets.

Step 5: Optimize for Real Passive Income

Rotate Incentive Tokens into Stable Assets
Convert volatile reward tokens into stablecoins for predictable yield.
Rebalance Between Vaults
Shift allocation toward higher real APY vaults when incentives fade.
Avoid Chasing High APY Alone
Focus on risk-adjusted yield, not just advertised numbers.

Tools to Track Real vs Incentive Yield

Aggregator Dashboards: Tulip, SoraLabs, Beefy
Portfolio Trackers: Zerion, Debank, ApeBoard
Spreadsheet Tracking: Record deposit, rewards, USD value, and fees

Common Mistakes to Avoid

Chasing the Hottest Vaults
- Temporary incentives can create APY illusions
- Solution: focus on real yield history
Ignoring Fees and Slippage
- Reinvesting reward tokens may cost you
- Solution: calculate net APY after fees
Not Adjusting for Volatility
- LP tokens can reduce real returns if impermanent loss occurs
- Solution: combine with stablecoins and diversify

Example Scenario: Mixed Vault Portfolio

Portfolio: $10,000 total

$5,000 in USDC stable vault (Real APY 8%)
$5,000 in SOL/USDC LP vault (Real APY 12%, Incentive APY 15%)

Calculation:

Stable vault contribution: $5,000 × 8% = $400
LP vault contribution: $5,000 × 12% = $600
Portfolio Real APY = ($400 + $600) / $10,000 = 10%

Even though the LP vault shows 27% APY advertised, the real portfolio yield is 10%, reflecting both stable yield and risk-adjusted LP returns.

Final Takeaways

Real APY vs Incentive APY matters for predicting actual passive income
Incentive-heavy vaults are high-risk, high-reward, suitable for a smaller portion of your portfolio
Stablecoins provide predictable, low-risk yield, ideal for portfolio foundation
Regular monitoring and rebalancing ensure optimal income over time
Use dashboards and trackers to measure performance in USD-equivalent terms, not just APY percentages

By understanding the difference between real and incentive APY, you can make informed decisions, reduce risk, and optimize your passive income in crypto yield aggregators.
