Crypto Fees Scanner

On-chain investing makes fees feel invisible. A small percentage skimmed from a vault here, a swap fee there, a borrow rate that drifts higher over a few weeks. Each one looks trivial in isolation. Over a full market cycle they quietly become one of the biggest factors deciding what your portfolio is actually worth.

This crypto fees calculator exists to make that drag visible. Instead of trusting a headline APY, you can see in dollars how much of your potential gains never reaches your wallet because they were paid away in fees over time.

The scanner answers one focused question. If your portfolio grows at a given gross return, how much do annual fees cost you over the period you hold it? It models two versions of the same portfolio side by side and shows you the gap between them.

That gap is the fee cost. It is the money you would have kept if the same positions carried no fees at all. Seeing it as a single dollar figure tends to be far more persuasive than a percentage buried in a protocol page.

The tool takes your starting amount, your expected gross annual return, your annual fee rate, and the number of years you plan to stay invested. It then compounds two balances forward in parallel.

The first balance grows at the full gross return each year. The second grows at the gross return minus the annual fee. Both start from the same place, but they separate a little more every year. The distance between the two lines at the end is the total dollars lost to fees.

• Gross path: your capital compounding at the headline return with no fee applied
• Net path: the same capital compounding at gross return minus the annual fee
• Fee cost: the difference between the two balances at the end of the period
• Percent of gains lost: fee cost expressed as a share of your gross profit

A 1 percent annual fee sounds harmless. The problem is that compounding works against you as well as for you. Every dollar paid in fees is a dollar that never compounds in future years, and the gap widens with each passing year.

Over one year a 1 percent fee on a 10 percent return costs you roughly a tenth of your profit. Over ten or twenty years, because the lost dollars would themselves have compounded, that same fee rate can quietly erase a meaningful slice of your final balance. Time is the multiplier that makes DeFi fees expensive.

Fees on-chain are spread across many layers, which is exactly why they are easy to underestimate. A single yield position can touch several of them at once.

• Protocol fees: a cut taken by the protocol on yield or activity, common on lending markets and DEXs
• Vault management and performance fees: yield aggregators like Yearn or Beefy charge an annual management fee plus a share of profits
• Swap fees: the trading fee paid to liquidity providers and the protocol on every DEX swap on Uniswap, Curve or similar venues
• Bridge fees: the cost of moving assets between chains, which adds up if you rebalance across networks often
• Gas: the network fee paid on every transaction, which matters most for small positions and frequent activity
• Bad borrow rates: an elevated borrow APR on Aave, Morpho or Compound is an ongoing cost that behaves exactly like a fee on your position

Enter the amount you are putting to work, the gross annual return you realistically expect, and the all-in annual fee that applies to those positions. Add the holding period in years. Keep the gross return honest, since an inflated return makes the fee look smaller than it really is.

The results split into a few clear numbers. Your balance with fees, your balance without fees, the potential savings between them, and the percent of your gross gains that fees consumed. The last figure is often the most sobering, because it reframes a small annual rate as a large share of your hard-won profit.

You cannot remove fees entirely, but you can stop overpaying for them. Most of the savings come from awareness rather than from chasing the absolute cheapest venue every time.

• Compare net yield, not gross APY, when choosing between vaults or markets
• Batch transactions and avoid unnecessary swaps to cut gas and swap fees
• Prefer direct positions over wrapper vaults when the management fee is not justified by the work the vault does
• Watch your borrow rates and refinance or repay when a market turns expensive
• Bridge less often and consolidate activity on the chains where you actually transact

The most frequent error is anchoring entirely on the headline APY. A vault advertising a higher gross yield can easily deliver a lower net result once its management and performance fees are applied. The number that pays your rent is the net number.

The second mistake is treating fees as a one-time cost. A management fee is not paid once, it is paid every year on a balance you hoped would keep compounding. Ignoring that recurring fee drag is how investors end up surprised by a final balance that trails the brochure.

Suppose you deploy 50,000 dollars into a yield strategy expecting a 12 percent gross annual return, and the all-in fees come to 2 percent per year. You plan to hold for 10 years.

The gross path compounds at 12 percent and the net path compounds at 10 percent. After 10 years the no-fee balance is meaningfully larger, and the gap between the two runs into tens of thousands of dollars. A large part of that gap is not the fees themselves but the compounding those fee dollars would have earned if they had stayed in your portfolio.

This is a model, not a forecast. It assumes a steady gross return and a constant fee rate, while real markets are volatile and real fees change as protocols update their parameters and as you move between positions.

Use it to build intuition about the scale of fee drag and to compare scenarios, not to predict an exact future balance. The point is directional truth. Fees cost more than they appear, and the longer you hold, the more they cost.

A calculator shows you the math once. Otomato watches it continuously. It detects the positions you actually hold across chains, reads the live rates attached to them, and tracks how those rates move over time.

When a borrow rate climbs, a vault fee changes, or a yield drops below what you are paying to hold a position, Otomato flags it so you can act before the drag compounds. You paste a wallet address, and from then on the portfolio monitors itself for the moment a fee or rate turns expensive on you.
