Fee collection and reinvestment — interest on interest

The APR formula

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

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

Example:

ParameterValue
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 componentPer daySource
Options cost (theta)−$3.25Insurance premium
Debt interest−$0.774,704 × 0.06 / 365
Total costs−$4.02
LP capital$3,200
Breakeven APR(4.02 × 365) / 3,200 = 45.9%

Are we above breakeven?

MetricValueStatus
Current LP APR67.9%
Breakeven APR45.9%
Coverage ratio67.9 / 45.9 = 1.48xSafe
Surplus22.0% APR above the minimum
ℹ️
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.

The weekly income-collection cycle

Every week, collect your income and allocate it:

  1. Collect LP feesOrca/Meteora: claim the accrued income (the SOL and USDC portions)
  2. Convert the SOL portion to USDC (or keep it as SOL) via Jupiter
  3. 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)
  4. Update your numbers in the DeFi Risk OS platform
  5. Check the alerts — is LTV, the range, and the expiry all still normal?

How to allocate the income

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

Where it goesShareAmountWhy
SOLCollateral~40%~$16.66Lowers LTV, increases safety
USDC → Insurance Vault~30%~$12.50Saved for the next options roll
Surplus → Collateral~30%~$12.50Compounding effect
Total100%$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:

  1. Adding to collateral lowers LTV → further from liquidation
  2. The Insurance Vault saves up for the next options roll → the hedge never lapses
  3. 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):

MonthAccumulatedLP capitalAPR
1$178.50$3,20067.9%
6$1,071$3,20067.9%
12$2,172$3,20067.9%

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

MonthAccumulatedLP capitalEffective APR
1$178.50$3,25369.0%
6$1,135$3,54175.1%
12$2,402$3,92083.2%

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 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 situationExpected APRCoverageWhat to do
High activity (bull/bear market)70–100%+>1.5xReinvest more
Normal activity46–70%1.0–1.5xStandard cycle
Low activity (quiet market)20–45%<1.0xNarrow the range
Minimal activity<20%<<1.0xClose the LP, wait for better conditions
ℹ️
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.

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.
