Liquidity Pool APR: How to Estimate LP Fee Yield

What a Liquidity Pool APR Actually Measures

Every DEX analytics page advertises an APR next to each pool, and it is easy to read that number as a yield you will simply collect. It is not. A liquidity pool APR is a projection of today’s fee rate annualized forward — it takes how much the pool earned in fees over the last 24 hours, expresses that as a fraction of the pool’s size, and multiplies by 365. It tells you what you would earn if today’s trading activity repeated every day for a year. It is a snapshot, not a promise.

Understanding how that number is built lets you sanity-check any pool’s advertised APR and estimate your own dollar fee income before you deposit. This guide breaks down the calculation from TVL, volume, and fee tier, shows why the volume-to-TVL ratio is the real driver of yield, and walks through reading the results. The liquidity pool APR calculator applies every step for any pool whose stats you can read off its analytics page.

The Three Inputs and the Formula

A pool pays fees to its liquidity providers out of every trade routed through it, split proportionally by each provider’s share. Three numbers determine the fee APR:

• TVL (Total Value Locked) — the total dollar value of assets in the pool. This is the denominator; a bigger pool splits the same fees across more capital.
• 24h Trading Volume — the dollar value of trades routed through the pool in the last day. This is what generates fees.
• Fee Tier — the cut the pool takes from each trade. 0.3% is Uniswap v2’s classic rate; concentrated-liquidity (v3) pools commonly range from 0.01% to 1%.

The calculation runs in three steps:

1. Daily fees = 24h volume × fee tier
2. Daily fee rate = daily fees ÷ TVL
3. Annualized fee APR = daily fee rate × 365

Collapsing those steps reveals what actually matters:

• Annualized fee APR = (volume ÷ TVL) × fee tier × 365

The fee tier is fixed, and 365 is a constant, so the only variable a provider controls or watches is the volume-to-TVL ratio — how hard the pool’s capital is working. A pool that turns over half its TVL in daily volume earns twice the APR of one that turns over a quarter, at the same fee tier.

Why the Volume/TVL Ratio Is Everything

Because APR scales linearly with the volume-to-TVL ratio, that single ratio explains almost every difference between pools. The table below fixes the fee tier at 0.3% and varies only the daily turnover:

Daily volume ÷ TVL	Daily fee rate	Annualized fee APR
10%	0.030%	10.95%
25%	0.075%	27.38%
50%	0.150%	54.75%
100%	0.300%	109.50%
200%	0.600%	219.00%

The eye-catching triple-digit APRs at the bottom come from pools whose daily volume exceeds their TVL — typically small, hot, or newly launched pools. Those figures are also the least reliable, because a single day’s volume in a small pool can swing wildly. A deep, mature pool with a 10–25% turnover offers a far steadier, if lower, yield.

Worked Example

Take a pool with $1,000,000 TVL, $500,000 in 24h volume, and a 0.3% fee tier, and suppose you deposit $10,000 into it.

Step	Calculation	Result
Daily fees	$500,000 × 0.3%	$1,500
Daily fee rate	$1,500 ÷ $1,000,000	0.15%
Annualized fee APR	0.15% × 365	54.75%
Your pool share	$10,000 ÷ $1,000,000	1.0%
Your 24h fee income	$10,000 × 0.15%	$15.00
Your annualized fee income	$10,000 × 54.75%	$5,475

The pool turns over half its TVL each day, so at 0.3% it projects a 54.75% fee APR. Your $10,000 is 1% of the pool, so you receive 1% of the $1,500 in daily fees — $15 a day, or $5,475 over a year at today’s rate. That last qualifier is the whole point: if volume halves tomorrow, so does your income.

How to Use the Liquidity Pool APR Calculator

You supply the pool’s public stats and, optionally, your own stake:

1. Pool TVL (Total Value Locked) — the pool’s total value in dollars, read from its analytics page.
2. 24h Trading Volume — the dollar volume routed through the pool in the last 24 hours.
3. Fee Tier — the pool’s fee percentage (e.g. 0.3, or 0.05 for a low-fee concentrated pool). It is set when the pool is created.
4. Your Deposit (optional) — the dollar amount you plan to provide. Leave it blank for just the pool APR, or fill it in to get your personal income figures.

The tool returns the Annualized Fee APR, the underlying Daily Fee Rate, and — if you entered a deposit — Your Pool Share, Your 24h Fee Income, and Your Annualized Fee Income. Where do you find TVL, volume, and fee tier? Any DEX’s own analytics page, or an aggregator like DeFiLlama, shows them per pool.

How This Fits Your Workflow (and the Big Caveat)

This APR is deliberately a projection from a single day’s activity — not a historical average and not a guarantee. Both trading volume and TVL fluctuate day to day, and the figure ignores impermanent loss entirely. Fee APR and impermanent loss are the two halves of a liquidity provider’s real return: this calculator handles the gain from fees, and the impermanent loss guide and its calculator handle the drag from price divergence. A pool is only worth providing if the fee APR over your holding period comfortably exceeds the impermanent loss you expect. Some practical habits:

• Prefer steady turnover over spiky APR. A 15% APR on a deep pool with consistent volume can beat a 150% APR on a pool whose volume vanishes after launch week.
• Re-check volume regularly. The number reflects the last 24 hours only; treat it as a moving snapshot.
• Always net fees against impermanent loss. A high fee APR on a volatile pair can still lose to holding if the price ratio diverges far enough.
