Collecting and reinvesting fees

Elena's LP position earns $5.95 a day, about 68% APR in a teaching example, but costs of $4.02 a day come first. How APR and APY differ, how to calculate breakeven APR and the coverage ratio, and a 5-minute weekly routine.

The APR formula

LP yield is measured in APR (annual percentage rate). The formula is simple:

APR = (daily income × 365) / capital deployed × 100%

Example:

Parameter	Value
Daily income	$5.95
Capital deployed	$3,200 USDC
APR	(5.95 × 365) / 3,200 = 67.9%

APR vs APY — what's the difference?

APR = annual yield without reinvesting (simple)
APY = annual yield with reinvesting (compounded)

67.9% APR with daily reinvesting = ~97% APY

The difference comes from "interest on interest" — reinvested money starts earning too.

Breakeven APR — the minimum threshold

Breakeven APR is the minimum LP yield needed for the strategy to be profitable. Think of it as your reference point: as long as you are above it, fees cover the insurance and debt costs. Drop below it, and you simply narrow the range or move to a more active pool (the table below gives you a concrete action for every situation).

A breakeven analogy

Same idea as a business: if a shop's revenue does not cover rent and salaries, the business is losing money. LP fees have to cover the insurance and debt costs.

Formula:

Breakeven APR = (daily insurance cost + daily debt cost) × 365 / LP capital × 100%

Calculation for Strategy B:

Cost component	Per day	Source
Options cost (theta)	−$3.25	Insurance premium
Debt interest	−$0.77	4,704 × 0.06 / 365
Total costs	−$4.02
LP capital	$3,200
Breakeven APR	(4.02 × 365) / 3,200 = 45.9%

Are we above breakeven?

Metric	Value	Status
Current LP APR	67.9%
Breakeven APR	45.9%
Coverage ratio	67.9 / 45.9 = 1.48x	Safe
Surplus	22.0% APR above the minimum

A coverage ratio of 1.48x means income is 48% higher than the minimum required. Even if income dropped by ~30%, it would still cover the costs.

Coverage ratio — how to read it

Coverage ratio	Assessment	What to do
>2.0x	Excellent	Reinvest the surplus
1.5x – 2.0x	Good	Monitor, hold steady
1.0x – 1.5x	Minimal	Consider adjusting the range
<1.0x	Losing money	Action needed!

The weekly income-collection cycle

Every week, collect your income and allocate it:

Collect LP fees — Orca SOL or Meteora SOL: claim the accrued income (the SOL and USDC portions)
Convert the SOL portion to USDC (or keep it as SOL) via Jupiter SOL — only if the pool pays fees in two tokens
Allocate according to the plan:
- SOL portion → extra collateral (lowers LTV)
- USDC portion → the Insurance Vault (saved up for the next options roll)
- Surplus → extra collateral (compounding effect)
Update your numbers in your own spreadsheet (the DeFi Risk OS platform will do this automatically once it launches)
Check the alerts — is LTV, the range, and the expiry all still normal?

Step 2 does not always apply

Since Q1 2026, Meteora DLMM SOL supports "quote-only fees": you can set all fees to accrue in a single token (USDC only, for example). When you do, the conversion step — along with its swap fee and slippage — disappears from the cycle entirely. The same release added one-click zap-in from a single token, so manually balancing tokens before entering is no longer mandatory either.

Orca Whirlpool SOL fees are still accrued in both tokens, so step 2 stays there. Before committing capital, check how your specific pool pays out fees.

How to allocate the income

Say you collected $41.65 in a week ($5.95 × 7):

Where it goes	Share	Amount	Why
SOL → Collateral	~40%	~$16.66	Lowers LTV, increases safety
USDC → Insurance Vault	~30%	~$12.50	Saved for the next options roll
Surplus → Collateral	~30%	~$12.50	Compounding effect
Total	100%	$41.65

Why not put it all back into the LP?

Reinvesting 100% into the LP would boost income, but it would also raise risk:

Adding to collateral lowers LTV → further from liquidation
The Insurance Vault saves up for the next options roll → the hedge never lapses
Only the surplus goes toward growth → a balanced strategy

This is not about maximizing profit — it is about safety.

The growth effect over time

Without reinvesting (income just piles up):

Month	Accumulated	LP capital	APR
1	$178.50	$3,200	67.9%
6	$1,071	$3,200	67.9%
12	$2,172	$3,200	67.9%

With reinvesting (~30% of income → LP):

Month	Accumulated	LP capital	Effective APR
1	$178.50	$3,253	69.0%
6	$1,135	$3,541	75.1%
12	$2,402	$3,920	83.2%

Effective APR — the income rate measured against the original $3,200 capital (the pool's APR stays at 67.9%; it is simply a larger capital base doing the work).

Difference over a year: +$230 extra from the growth effect.

Once you understand this cycle, you can turn your weekly income collection into a system that grows itself — you decide deliberately how much goes to safety and how much to growth, instead of guessing.

The 90-day insurance renewal cycle

Every 90 days the options hedge needs renewing. That is what the Insurance Vault is for:

Accumulation:

Weekly USDC → Vault: $12.50
Over 90 days: $12.50 × 13 = $162.50

Insurance renewal cost: ~$150–$200
Coverage: ~81%–108%

The Insurance Vault = your options budget

The Insurance Vault is a dedicated fund that builds up from LP income and is used ONLY to buy options. It guarantees that the hedge never lapses.

If the Vault is full — the surplus goes to collateral. If the Vault is running low — increase the USDC share of your income.

What to watch — and what the platform will show

Once the platform launches, you will see these metrics in one place; until then, calculate them in a spreadsheet.

Metric	What it calculates	Purpose
Daily Carry	LP income − insurance − debt	Is today profitable?
Coverage Ratio	LP APR / Breakeven APR	Does income cover costs?
LTV	(Debt × 1.05) / (Collateral × price × 0.90)	Is the loan safe?
Vault %	Vault / Next renewal cost	Enough saved for insurance?
Days to renewal	Until nearest option expiry − 30d	When to renew?
LP Range %	(Price − Lower) / (Upper − Lower)	Where is the price in the range?

Where do the 1.05 and 0.90 in the LTV formula come from?

They are not the protocol's own calculation — they are this course's safety margin:

1.05 — a buffer for the debt interest that accrues between checks;
0.90 — a conservative haircut on the collateral value.

Kamino SOL works differently and without these weights, and the actual liquidation threshold depends on the collateral type, not on the protocol as a whole: for SOL collateral it is 0.75 (75%), for USDC collateral 0.90 (90%) — verified in September 2026. Our formula deliberately errs on the safe side: it reports a slightly higher LTV, so it warns you earlier than the protocol would. Kamino V2 runs many separate markets with different parameters — always check the numbers in the market where you actually open the position.

What happens when income drops?

LP income fluctuates — it depends on trading volume. That is not a surprise, it is a predictable variable: you have a prepared action for every market situation, so when volume drops you know exactly what to do:

Market situation	Expected APR	Coverage	What to do
High activity (bull/bear market)	70–100%+	>1.5x	Reinvest more
Normal activity	46–70%	1.0–1.5x	Standard cycle
Low activity (quiet market)	20–45%	<1.0x	Narrow the range
Minimal activity	<20%	<<1.0x	Close the LP, wait for better conditions

The APR ranges in this table are an illustration, not a forecast — a pool's actual APR moves daily and has to be checked live.

Volume is not the only variable — the fee tier can move too

The table above assumes the pool fee is fixed and only trading volume changes. Since May 2026 that is no longer true for every pool.

Orca SOL now has two kinds of pools:

Fixed fee — the fee stays constant (0.01% / 0.05% / 0.30% / 1.00%). APR moves with volume alone.
Adaptive fee — the effective fee is the base tier plus an adaptive component that rises with large price moves. In such a pool your fee APR moves for two reasons at once: volume and volatility.

So in an adaptive pool, an APR you extrapolated from a 0.30% tier will not match what you actually see. Orca's own documentation is explicit that adaptive fees do not guarantee a higher LP return — the higher fee arrives exactly when impermanent loss is also larger. Check which pool type you are choosing before you commit capital.

LP income can swing anywhere from 20% to 100%+ APR. The coverage ratio is the dial on your dashboard: above 1.0x, income covers costs. Below it, you already have a prepared move (narrow the range or switch pools), so you manage the situation instead of reacting in a panic.

Platform in development

Once the DeFi Risk OS platform launches, it will calculate your LP yield, breakeven APR, and coverage ratio automatically

For now, all of this is done by hand, as shown in the lesson.

Next module: Module 5 — Options. We will start with the anatomy of an option and work up to the Put/Call strategies that protect our portfolio.

Calculate the compound effect with a real fee APR

The compound effect becomes real once you calculate it with actual market numbers. Takes about 10 minutes — paper, a calculator, and the Orca page.

All calculations here are on paper — we are not opening real positions. Always look up the fee APR live on the page, since it changes constantly.

This is learning, not investing — use only small amounts you treat as tuition.

You just calculated the breakeven APR and coverage ratio for your own position — for most investors these numbers stay some abstract idea, but you already have them under control.
