Impermanent Loss on Solana, No Calculator: The 8-Second Rule

📅 Market analysis for October 3, 2026 · data as of 14:00 UTC · powered by live Wealthville Scores

A 2x move costs a 50/50 LP 5.7% before fees—burn that into your head.

The 8-Second Mental Model for IL

You don’t need a spreadsheet to reason about impermanent loss. For any 50/50 pool (AMM or CLMM while you’re inside the active range), use this rule:

• Square the price move. Divide by 8. That’s your IL percent for small moves. Example: a 20% move → 0.2² = 0.04; 0.04 ÷ 8 = 0.5% IL.

This approximation is tight up to ~20–30% moves. For bigger shocks, remember anchors (below). If you want the exact formula later, it’s IL = 2√r/(1+r) − 1, where r is the new price divided by entry price, but you don’t need it to make decisions on the fly.

Five Anchors to Know Cold

Memorize these. They’re symmetric for up or down moves of the same magnitude (1.5x is the same IL as 1/1.5).

• ±10% move → ~0.11% IL (rule gives 0.125%)
• ±20% move → ~0.41% IL (rule gives 0.5%)
• ±50% move (1.5x) → ~2.02% IL
• 2x (or 0.5x) → ~5.72% IL
• 3x (or 1/3x) → ~13.4% IL
• 5x → ~25.8%; 10x → ~42.4% IL

These five give you immediate intuition: modest moves barely dent you; large trends crush you unless fees are real. That’s the whole game.

Apply It to Live Solana Pools

Let’s run the mental model on four actual pools you can click and verify. For fee math, use daily turnover ≈ 24h volume ÷ TVL, then multiply by the fee tier to estimate daily fee yield. Annualize by ×365. Fee tiers vary by pool; if you don’t know the tier, do a what-if at 5 bps and 25 bps. Official fee references: Raydium docs, Orca docs.

Stable-stable: USDC-USDD (Raydium CLMM)

Data today: TVL $500K, 24h vol $4K, fee APR 0.0%, farmer score 100/100, risk 80/100.

• IL intuition: Stables should hug r≈1 most days. A 1% wobble → 0.01²/8 = 0.0000125 = 0.00125% IL. Even a 5% depeg only implies ~0.031% IL while you’re within range.
• Fees vs IL: Turnover = 4,000 ÷ 500,000 = 0.8% per day. If fee tier were 5 bps, daily fee ≈ 0.008% × 0.05% = 0.0004% → ~0.146%/yr. At 25 bps, it’s ~0.73%/yr. Both are tiny, consistent with the displayed 0.0% fee APR.

Takeaway: IL is small on true stables. The problem is fees. On Solana, many stablecoin CLMMs haven’t had the throughput to pay. See our prior take: Why No Stablecoin LPs Pay Real Yield on Solana Now.

Bluechip–memecoin: SOL-Neiro (Raydium AMM)

Data today: TVL $219K, 24h vol $40, fee APR 0.0%, farmer score 100/100, risk 61/100.

• IL intuition: A typical memecoin pop is +100% to +200% vs SOL. That’s 5.7%–13.4% IL. If it 5x’s versus SOL, IL is ~25.8%. That’s the cost of systematically selling the winner as it runs.
• Fees vs IL: Turnover = 40 ÷ 219,000 ≈ 0.018% daily. Even with a 25 bps fee, daily fee ≈ 0.000045% → ~0.017%/yr. That’s basically zero. You’d be taking IL without a fee engine to pay you back.

Memecoin–stable: BOOP-USDC (Orca Whirlpool)

Data today: TVL $189K, 24h vol $0, fee APR 0.0%, farmer score 100/100, risk 39/100.

• IL intuition: Same anchors. A 50% move → ~2.0% IL; 2x → 5.7%. Inside your chosen CLMM range, the math mirrors a 50/50 AMM.
• Fees vs IL: With $0 volume, fees are literally zero regardless of fee tier. Fee APR reads 0.0%. If you’re posting liquidity here, your expected return is negative unless you have a very specific flow thesis (and timing).

Bluechip–microcap: SOL-TINY (Raydium CLMM)

Data today: TVL $154K, 24h vol $29, fee APR 0.3%, farmer score 100/100, risk 83/100.

• IL intuition: Treat in-range like 50/50. A 20% move in TINY vs SOL costs ~0.41% IL; a 2x run costs ~5.7% if you remain in range the whole way.
• Fees vs IL: Turnover = 29 ÷ 154,000 ≈ 0.019% daily. Even at 100 bps fee, that’s 0.00019%/day → ~0.07%/yr. The displayed 0.3% fee APR suggests sporadic bursts; sustained fee cover at current flow doesn’t pencil out.

Concentrated Liquidity: What Changes (and What Doesn’t)

Three rules keep you out of trouble on CLMMs (Raydium CLMM, Orca Whirlpool):

• While in range, use the same IL rule. The pool behaves locally like a 50/50 AMM around the current price. A 20% move before you hit an edge → ~0.41% IL.
• Edges arrive sooner on narrow ranges. A ±10% range hits its edge on a 10% move. A ±100% range gives you more room. Narrow ranges magnify fee density but make edge hits common.
• Beyond the edge, you’re stuck in the loser. Break up through your upper tick? You end up almost entirely in quote (e.g., USDC), missing further upside. Break down? You concentrate in the base (e.g., SOL or the volatile token) as it falls. From there, your PnL tracks that single asset until you rebalance back into range.

A quick way to bound max pain after you’re out-of-range:

• Up-move beyond the upper tick: pretend you’re 100% in quote. HODL appreciates with the winner; you don’t. Your underperformance grows roughly with the further price increase.
• Down-move beyond the lower tick: pretend you’re 100% in base. If price keeps falling 50%, 75%, 90%, your LP is effectively long that path the whole way down, while HODL had half in the safer side.

That’s why range selection must start with an honest view of expected directional volatility. Don’t set a ±10% box on a coin that routinely gaps 40% overnight and then wonder why you wake up out-of-range (we’ve all done it once).

Fees vs IL: The Two-Number Break-Even You Can Do Mentally

You only need two inputs to decide if an LP is sane for you today:

1. Turnover = 24h volume ÷ TVL (as a percent). This approximates how much of the pool churned today.
2. Fee tier (in bps). Multiply turnover × fee tier to get daily fee yield. Multiply by 365 to annualize.

Then compare that fee yield to your expected IL, using the 8-second rule and your view of how often certain moves occur.

• If you think a 20% move happens monthly in a volatile pair, that’s ~0.41% IL × 12 ≈ ~5.0%/yr IL cost in expectation. Your fees need to exceed ~5%/yr net for this to make sense (plus a margin for being out-of-range part of the time).
• If you think a 2x event happens once a quarter in a memecoin vs SOL pool, that’s 5.7% × 4 = ~23%/yr expected IL from those runs alone. That requires serious fee density. Most pools won’t come close.

Now check the four pools above. With turnover at 0–0.8% daily and many fee tiers far below 25 bps in practice, none of them support a fees-first LP thesis at current flow. The displayed fee APRs (0.0% to 0.3%) back that up.

When to LP, When to Walk Away

Here’s the contrarian view: Most Solana LPs don’t need a better calculator— they need restraint. If the pool isn’t showing sustained turnover and fee capture, the 8-second rule tells you IL will dominate your PnL. The “APR” banner won’t save you if it’s just a backfilled blip or an emission you can’t bank at exit.

• LP when you see consistent flow at a known fee tier and your range matches price behavior (and you can babysit it). Emphasis on consistent.
• Don’t LP thin pools hoping for flow tomorrow. Tomorrow’s flow is not yours today. You warehousing inventory for free is altruism, not a strategy.

Your Pocket Cheat Sheet

• The rule: IL ≈ (price move squared) ÷ 8 for moves ≤20–30%.
• Anchors: 10% → 0.11%; 20% → 0.41%; 50% → 2.02%; 2x → 5.72%; 3x → 13.4%.
• CLMM twist: Same IL in-range; out-of-range you’re stuck in the loser until rebalance.
• Fees quick-test: Daily fee ≈ turnover × fee tier. Annualize ×365. Compare to expected IL.
• Reality check: If fee APR < expected IL, you’re subsidizing traders. Close or widen.
• Sanity linkbacks today: USDC-USDD, SOL-Neiro, BOOP-USDC, SOL-TINY.

FAQ

What exactly is impermanent loss?

It’s the underperformance of a 50/50 liquidity position versus simply holding the two assets, given a price change. In a constant-product pool you continuously sell the rising asset and buy the falling one, so trending markets make you lag HODL. The classic formula is IL = 2√r/(1+r) − 1, where r is the price ratio after the move.

Does concentrated liquidity reduce IL?

Not inherently. While you’re in-range, your IL per move is the same as a 50/50 AMM around the current price. Concentration boosts fee density if flow crosses your range. Once price leaves the range, you become fully one-sided and can underperform HODL quickly if the trend continues.

How do I estimate fee APR without a dashboard?

Two steps: (1) daily turnover = 24h volume ÷ TVL, (2) daily fee ≈ turnover × fee tier (in %). Annualize by ×365. Example: turnover 1% and 20 bps fee → 0.2 bp/day → ~0.73%/yr. Compare that to expected IL from the moves you think will happen.

Is IL zero on stablecoin pairs?

No. It’s small when the peg holds (e.g., 1% move → ~0.00125% via the rule), but not zero. The bigger issue on Solana’s stable pools lately is insufficient volume to generate meaningful fees. Without fees, even tiny IL makes the trade unattractive.

How do I handle memecoin blow-offs in this model?

Use the anchors. A 2x run implies ~5.7% IL; 3x is ~13.4%. If you expect that kind of move frequency, your pool must be printing double-digit fee APRs and your range must be where the trades actually happen, or you’ll underperform HODL by a lot.

Should I hedge IL?

You can, but you’re then running an active basis/option strategy (short gamma in the pool, long gamma via options or futures). On Solana, instrument depth and costs matter. For most LPs, a fees-first selection and disciplined range management beat complex hedges.
