What Is a High-Water Mark? Fees and Drawdown Explained
A high-water mark is the highest net asset value a fund has ever reached, and performance fees are only charged on gains above it. If a fund loses money, the manager must recover past losses before earning fees again, which keeps fee incentives aligned with yours.
What is a high-water mark in finance?
A high-water mark is the highest value a fund's net asset value has reached at the end of a prior period. A manager can only charge performance fees on gains above that peak, so a fund that loses money must recover the loss before earning performance fees again. Investor.gov, the SEC's education site, defines the term as a benchmark used to ensure managers earn fees only on new profits, not on recovering past losses (Investor.gov glossary).
The mechanism exists to align incentives: without it, a manager could profit twice on the same dollars, first on the gain and again on the recovery. The same logic appears in prop-firm drawdown rules, where a funded account's loss limit often trails the equity peak rather than a fixed starting balance.
How does a high-water mark work in a hedge fund?
A hedge fund charges a performance fee, typically 20%, only on profits above the fund's high-water mark. The mark is the highest net asset value the fund has ever reached. If the fund loses money, the mark stays where it was, and the manager must climb back to it before earning another performance fee.
Suppose a fund starts at $100M, charges fees on gains, and drops to $85M after a bad stretch. The manager now has to grow the fund past its previous peak before any new performance fee is due. That protects investors from paying twice for the same recovery.
The incentive problem it solves
Without a high-water mark, a manager who loses 20% could charge fees on the rebound year even though investors are still underwater. The mark makes recovery gains fee-free, aligning the manager's payout with actual investor profit. The same mechanic shows up outside hedge funds: prop firms apply high-water-mark drawdown rules to funded accounts, and copier setups that scale risk per follower (see the modes in the Trademetry docs) inherit the same recovery dynamics on your equity curve.
How do you calculate a high-water mark step by step?
The high-water mark is the highest net asset value your account has reached at a fee crystallization date. You never pay performance fees until equity exceeds that number, and the mark only moves up, never down (Investopedia).
Step 1: set the initial mark
At inception, the mark equals your starting equity. A $100,000 evaluation account opens with a high-water mark of $100,000. If you take over a funded account mid-cycle, set the mark to its equity on the day you assume control, because that is the value the fee or drawdown rule measures against.
Step 2: track net asset value each period
At every crystallization date, usually month-end, compute net asset value: closing equity, plus deposits, minus withdrawals. Adjusting for deposits and withdrawals matters, because a $5,000 top-up is not trading profit, and counting it as one would inflate your gain.
Step 3: update the mark only on new equity highs
This is the whole mechanic in one place. If end-of-month net asset value sits below the current mark, nothing changes: the mark stays where it is, and next month's performance fee is still calculated against the old peak. Only when net asset value exceeds the mark does the mark ratchet up to that new high, and any gain above the old mark becomes fee-eligible. A losing month never lowers the mark; it simply leaves it frozen, so you must recover the full drawdown before earning performance fees again. This is the same asymmetry prop firms apply to payout rules on funded accounts: your daily loss limit and drawdown are measured against equity levels that do not reset just because you had a good week. Tools like MetaCopier handle the copying side across follower accounts, and we compare the trade-offs in Trademetry vs MetaCopier, but the mark itself is arithmetic you can run in a spreadsheet: one column for net asset value, one for the running maximum.
Worked example: four years of returns with fees at each step
Here is a $1,000,000 account with a 20% performance fee and a high-water mark set at $1,000,000 on day one. The fee applies only to gains above the current high-water mark, and the mark only moves up.
Year-by-year fee math
| Year | Start value | Gross return | End value | High-water mark | Gains above HWM | Fee (20%) |
|---|---|---|---|---|---|---|
| 1 | $1,000,000 | +25% | $1,250,000 | $1,000,000 | $250,000 | $50,000 |
| 2 | $1,200,000 | −10% | $1,080,000 | $1,250,000 | $0 | $0 |
| 3 | $1,080,000 | +15% | $1,242,000 | $1,250,000 | $0 | $0 |
| 4 | $1,242,000 | +20% | $1,490,400 | $1,250,000 | $240,400 | $48,080 |
Year 1 is straightforward: the account beats the old mark by $250,000, so the manager earns $50,000. In Year 2 the loss drops the account below the $1,250,000 mark, so no fee is due despite the manager keeping Year 1's fee. Year 3 recovers most of the loss but still finishes under the mark, so the investor pays nothing. Only in Year 4 does the account clear the old peak, and the fee is charged on the $240,400 above it, not on the full $208,400 gain from Year 4's starting value. That distinction is the whole point of the mechanism.
What the investor actually pays over the period
Total gross profit is $490,400; total fees are $98,080, or about 20% of net gains. Without the high-water mark, fees on all four years' positive returns would have been higher, because Years 3 and 4 would each trigger charges on their full gains. The mark ensures the manager is paid once per dollar of new profit, not twice.
If you run funded accounts, the same logic shows up in how prop firms measure drawdown from your equity peak, which is why tracking your own high-water mark per account matters. Tools like Trademetry do that per-account math for you across copied followers, and comparisons such as Trademetry vs MTAPI.io cover how that stacks up against alternatives.
High-water mark vs hurdle rate: what's the difference?
A high-water mark is a floor on cumulative gains: fees are only charged on profit above the best previous equity point. A hurdle rate is a minimum return, usually tied to a benchmark like T-bills, that must be cleared before performance fees apply at all. The mark looks backward at your own peak; the hurdle looks outward at an external target. Prop traders meet the high-water version constantly, since funded-account rules track drawdown from peak equity, as documented on pages like Heron Copier's guide to prop-firm drawdown tracking.
When both apply together
Many funds stack them: you must beat the hurdle rate first, and even then fees apply only on gains above the high-water mark. A 6% year with an 8% hurdle earns nothing, even if equity sits above the old peak. For a money manager running follower accounts, that means one bad stretch can suppress fees for years, so track each account's peak separately, as Trademetry does per account (docs).
What happens to the high-water mark after a losing year?
After a losing year, the high-water mark stays at its old peak rather than resetting. If a fund's HWM is $120 and it drops to $100, the manager owes no performance fees until the fund climbs back above $120. Only gains above that prior peak count as new profit.
This is the point of the structure: it stops you from charging fees twice on the same money. A manager who loses 20% and then makes 20% is back to break-even, so the fee stays paused even though the recovery year looks profitable on paper.
Some funds do reset the HWM after a loss, but that requires investor consent and is rare in practice.
Where prop traders and signal providers hit high-water marks
High-water-mark drawdown in funded accounts
Prop firms rarely call it a high-water mark, but the mechanic is the same: your equity peak becomes the reference line, and daily loss limits or trailing drawdown are measured against it. On an evaluation account, that means a strong winning day can tighten your room for error the next morning, because the limit now trails a higher equity peak. Traders running several funded accounts through a trade copier feel this sharply: one master trade that spikes equity across five followers can push every account closer to its own trailing limit at once. Sizing rules that account for per-follower risk, not just master-account risk, are how you keep a single copy trade from breaching limits on accounts with different drawdown buffers.
Performance fees on master accounts
Signal providers and money managers face the other side of the concept. On MetaTrader's signal service, subscription-based copying charges followers on terms set by the provider, and anyone pricing a success fee on a master account should define whether the fee applies to new profits above the previous equity peak or to every gain. The second method charges followers twice for recovered drawdown, which is exactly what a high-water mark exists to prevent. Before you publish fee terms, write out the same two-year calculation you would want as a follower: loss year, recovery year, and confirm the recovery year only pays on profit above the old peak. Platforms differ on defaults, so check the terms on the marketplace you use, such as the MQL5 signal service, rather than assuming a high-water mark is applied for you.
What are the limitations of high-water mark provisions?
A high-water mark only protects investors if it is written and enforced correctly, and three weaknesses show up repeatedly.
First, deposit resets. Many agreements let the manager reset the mark when new money comes in, so a fund that is underwater can effectively lower the bar and charge fees on recovery the investor never earned.
Second, crystallization timing. If fees crystallize annually, a manager can post a strong ten months, take the fee, and give it all back in the last two months, leaving the investor paying for gains that evaporated. Monthly crystallization narrows this window but does not close it.
Third, withdrawal games. Partial redemptions can be structured so the mark recalculates in the manager's favor, and losses taken after a fee is crystallized never claw that fee back.
If you run client or funded accounts, read the exact clause: the definition of the mark, when it resets, and how deposits and withdrawals are treated decide who the provision actually protects.
FAQ
Is a high-water mark the same as a drawdown limit?
No. A high-water mark is the equity peak that performance fees are measured against, while a drawdown limit is the maximum loss allowed before an account is penalized or breached. They share a mechanic, though: prop firms often set trailing drawdown limits relative to your equity peak, so the same ratcheting logic applies to both.
Do I pay performance fees if I withdraw and redeposit at a lower value?
Deposits are not trading profit, so they should be excluded when net asset value is calculated, and withdrawals are subtracted the same way. If your equity is lower after the adjustment, the mark stays frozen and no fee is due until gains exceed the old peak. Check the agreement, since some clauses reset the mark on deposits.
How often is a high-water mark reset or crystallized?
The mark itself never resets downward; it only ratchets up when net asset value makes a new high. What crystallizes is the fee, usually at month-end or year-end. Shorter crystallization periods narrow the window where a manager books a fee on gains later handed back, but no interval eliminates that risk entirely.
Can a fund change or remove its high-water mark provision?
Changing the provision generally requires investor consent, and removal is rare because it lets the manager charge fees on recovering past losses. Some funds do negotiate a reset after a drawdown, but investors should expect something in return. Read the exact clause covering amendments before committing capital.
