Staking + Lending: How to Calculate Your Blended Passive Yield
Most passive-income guides treat staking and lending as an either-or choice. In practice, experienced crypto holders do both: stake the assets they want to keep long-term, lend the stablecoins they want liquid. The result is a blended yield — one number that describes what the whole stack earns.
Calculating that number is simple arithmetic, but doing it honestly means accounting for validator commissions, platform fees, and the very different risks each side carries. A blended 5% that ignores a depeg scare is not the same as a blended 5% built on solid ground.
This post gives you the formula, a $20,000 worked example across three allocations, and the risk adjustments that turn a spreadsheet number into a real expectation.
The Blended Yield Formula
Blended APY is just a weighted average:
Blended APY = (staking weight × net staking APY) + (lending weight × net lending APY)
The word "net" does the heavy lifting. Start from the advertised rate, then subtract everything that leaks: validator commission (typically 5–10% of staking rewards), protocol or platform fees on lending, and any auto-compounding costs. A 3.55% gross staking APY with a 10% commission is 3.2% net. A 6.5% advertised lending APY with platform spread is often ~5.8% net. Always calculate with net figures — this is the same fee-drag discipline behind our laddered staking math, where every leak compounds against you.
Worked Example: $20,000 Across Three Allocations
Assume 3.2% net staking APY (ETH delegation after commission) and 5.8% net lending APY (USDC on a major protocol — check current rates on CoinGecko's DeFi pages and the protocol's own docs, e.g. Aave's official documentation). Here is what three different splits earn per year:
| Allocation (stake / lend) | Blended APY | Yearly income on $20k | Liquidity profile |
|---|---|---|---|
| 80% / 20% | 3.72% | $744 | Mostly locked, lowest income |
| 50% / 50% | 4.50% | $900 | Balanced: half liquid, half earning base yield |
| 20% / 80% | 5.28% | $1,056 | Mostly liquid, highest income — highest smart-contract exposure |
The 50/50 split is the popular default for a reason: $900 a year with half the stack withdrawable at any time. But notice the trade-off hiding in the last column — every extra point of yield comes from the lending side, which carries smart-contract and depeg risk that staking does not.
Key takeaway: Blended APY is (weight × net APY) summed across both sides — and "net" means after validator commissions and platform spreads, not the advertised headline rate.
Adjusting for the Risks Each Side Hides
A blended number is only useful if you haircut it for risk. On the staking side, the main drags are validator commission (already in the net figure), potential slashing events, and unbonding lock-ups that trap your capital during crashes — our staking vs lending safety comparison walks through these in detail.
On the lending side, the risks are different: smart-contract exploits, stablecoin depegs (a "5.8% APY" on a stablecoin that drops to $0.97 is not 5.8%), and utilization-driven rate swings — lending APYs can halve in a week when borrow demand dries up. A conservative approach: reduce the lending APY in your formula by 1–1.5 percentage points as a risk haircut, then decide if the blend still beats your target.
A quick risk-adjusted check
Take the 50/50 blend at 4.50%. Apply a 1-point haircut to the lending half: (0.5 × 3.2%) + (0.5 × 4.8%) = 4.00%, or $800/year on $20k. If $800 still meets your goal, the allocation is sound; if you needed the full $900, you were counting on luck, not math.
Key takeaway: Haircut the lending side by 1–1.5 points for smart-contract and depeg risk before you commit. A blended yield that survives the haircut is a plan; one that doesn't is a hope.

Conclusion
Staking plus lending is the most practical passive-income setup in crypto: staked assets for base yield, lent stablecoins for liquidity and a kicker. The math is a simple weighted average, but the honesty is in the inputs — net rates after all fees, plus a risk haircut on the lending side. Do that, and your blended APY is a number you can actually plan around.
