Is 1% a day realistic in forex? The arithmetic of compounding

No, 1% a day is not a realistic expectation in forex. Compounded over about 250 trading days it would multiply an account roughly 12 times in a single year, and over five years about 250,000 times, a rate no one sustains. The arithmetic of compounding is straightforward, and working it through is the quickest way to see why the screenshots and promises on social media do not add up.

This guide explains the compounding formula, runs worked examples at daily and monthly rates, covers the rule of 72, and then looks at what real-world trading does to the neat curve: uneven returns, drawdowns, costs, deposits and withdrawals, and the risk you would need to take to chase a big monthly number. All figures are illustrative arithmetic, not expected or achievable results.

The compounding formula

Compounding means each period's return is earned on the balance at the start of that period, including earlier gains. The formula is:

Ending balance = starting balance × (1 + r) to the power n

Here r is the return per period as a decimal (1% is 0.01) and n is the number of periods. The period can be a day, a month or a year, as long as r and n use the same one.

The same formula works in reverse. A loss of 1% a period is r = −0.01, and the balance shrinks by 1% of an ever-smaller figure.

The compounding calculator does this for you, including optional regular deposits and withdrawals, so you can test any rate and period. The rest of this guide does the sums by hand so you can see what is going on.

Worked example: 1% a day

Take an illustrative starting balance of £1,000 and assume 1% growth every trading day. Forex trades on weekdays, so a year has roughly 250 to 260 trading days; we will use 250.

• After 20 trading days, about a month: 1.01 to the power 20 ≈ 1.220, so about £1,220.
• After 250 trading days, about a year: 1.01 to the power 250 ≈ 12.03, so about £12,032.
• After 500 trading days, about two years: ≈ 144.8 times, so about £144,800.
• After 1,250 trading days, about five years: ≈ 252,000 times, so about £252 million.

The first year's figure already implies a return of about 1,100%. The five-year figure would turn a modest account into one of the larger private fortunes in most countries. If a repeatable 1% a day were available, the same maths would apply to a fund with billions, and it would quickly own a meaningful share of the world's financial assets. That does not happen, which tells you the input is wrong, not the formula.

A daily target also hides a practical problem. To make 1% every day, you must not have losing days, or you must make more on other days to compensate. Any strategy that trades often will have strings of losing days; the guide to risk of ruin shows how common long losing streaks are even for a strategy with a genuine edge.

Worked example: monthly rates

Monthly targets sound more modest. Here is £1,000 compounded at different monthly rates, again purely as arithmetic:

• 1% a month: after 12 months ≈ £1,127 (about 12.7% for the year); after 36 months ≈ £1,431; after 60 months ≈ £1,817.
• 2% a month: after 12 months ≈ £1,268 (about 26.8% for the year); after 36 months ≈ £2,040; after 60 months ≈ £3,281.
• 5% a month: after 12 months ≈ £1,796; after 36 months ≈ £5,792; after 60 months ≈ £18,679.
• 10% a month: after 12 months ≈ £3,138; after 36 months ≈ £30,913; after 60 months ≈ £304,482.

Notice how quickly the rates diverge. 10% a month sounds like ten times 1% a month, but over three years it produces about 31 times the starting balance against about 1.43 times. That is the power, and the trap, of compounding: small changes in the assumed rate produce enormous changes in the result, which is why marketing material likes to quote monthly or daily figures.

For context, a year in which a broad stock market index rises by 20% is generally considered a strong year, and professional fund managers with research teams often fail to beat their benchmark index over long periods. A sustained 2% a month, about 27% a year, would already be an exceptional long-term record. Claims of 10% a month, sustained for years, should be treated as a red flag.

The rule of 72

The rule of 72 is a quick way to estimate how long it takes to double money at a steady compound rate:

Periods to double ≈ 72 ÷ percentage return per period

It is an approximation that works best for rates between about 2% and 15% per period. Some examples, with the exact figure for comparison:

• 10% a year: 72 ÷ 10 = 7.2 years. Exact: about 7.27 years.
• 5% a month: 72 ÷ 5 = 14.4 months. Exact: about 14.2 months.
• 2% a month: 72 ÷ 2 = 36 months. Exact: about 35.0 months.
• 1% a month: 72 ÷ 1 = 72 months. Exact: about 69.7 months.

The exact answer is the natural logarithm of 2 divided by the natural logarithm of (1 + r). For 1% a month that is 0.6931 ÷ 0.00995 ≈ 69.7. The rule of 72 is good enough for a sanity check: if someone claims an account doubles every few months, you can see at once that implies a monthly rate in the teens or higher.

Why real returns are not smooth

The formula assumes the same return every period. Trading results are nothing like that. Even a strategy with a genuine edge produces a jagged sequence of gains and losses, and that unevenness has a cost of its own.

Volatility drag

Gains and losses do not cancel out when they are the same percentage size:

• +10% then −10%: 1.10 × 0.90 = 0.99, a 1% loss.
• +20% then −20%: 1.20 × 0.80 = 0.96, a 4% loss.
• +50% then −50%: 1.50 × 0.50 = 0.75, a 25% loss.

The bigger the swings, the bigger the shortfall. This is called volatility drag. A rough rule is that the compound growth rate is about the average return minus half the variance of returns. As an illustration, an average of 2% a month with monthly swings of about 10% either way (a standard deviation of 10%) compounds at roughly 2% − (0.10 × 0.10 ÷ 2) = 1.5% a month, not 2%.

An illustrative six months

Suppose an account has these monthly results: +20%, −15%, +10%, −10%, +15%, −20%. The simple average is exactly 0%. The compound result is 1.20 × 0.85 × 1.10 × 0.90 × 1.15 × 0.80 ≈ 0.929, a loss of about 7.1%.

That is why a trader who says "I average 5% a month" may not have grown the account at 5% a month, or at all. Always ask for the compound result from start to finish, net of deposits and withdrawals.

Drawdowns change the maths

Losses are harder to recover from than they look. A 20% drawdown needs a 25% gain to recover; a 50% drawdown needs 100%. The guide to drawdown and recovery works through the figures. A strategy that compounds steadily for eleven months and then has one bad month can easily end the year behind a slower, steadier one.

What risk does 10% a month require?

Work backwards from the target. Suppose a strategy has a 40% win rate, wins average twice the amount risked and losses average the amount risked (a 1:2 risk-reward ratio). Its expectancy is:

(0.40 × 2) − (0.60 × 1) = +0.2R per trade

where R is the amount risked on each trade. That is already a good strategy, and these are illustrative assumptions, not typical results.

If you take 20 trades a month, the expected result is 20 × 0.2R = 4R a month. To turn 4R into 10% of the account you would need to risk about 2.5% of the account per trade (ignoring compounding within the month).

Now look at the variation around that average. With 20 trades at a 40% win rate:

• About 1 month in 4 would have 6 or fewer wins, which is a net loss even with the edge exactly as assumed.
• A run of ten losses in a row costs 1 − 0.975 to the power 10 ≈ 22.4% of the account at 2.5% risk per trade. At a 40% win rate, a ten-loss streak has roughly a 45% chance of turning up somewhere in 250 trades, about a year at this pace.

If the win rate were 50% with the same 1:2 ratio, the expectancy would be +0.5R and 1% risk would be enough on paper. But a 50% win rate at 1:2 after costs is a very large edge that few retail traders demonstrate over a meaningful sample. If the true edge is smaller than you think, the higher risk needed to hit the target remains, while the cushion disappears.

This is the core problem with return targets. The position sizing maths runs from the stop distance and the account, not from the amount you want to make. Choosing a monthly target first and then sizing up to reach it is how many accounts end up in a deep drawdown.

Costs drag on compounding too

Every trade pays a spread and possibly commission and swap. Those costs come off the balance whatever the outcome, and they compound in the wrong direction.

Worked example

Illustrative assumptions: risk 1% per trade with a 20-pip stop, and a round-trip cost of 1 pip. The cost is 1 ÷ 20 = 5% of the amount risked, or 0.05% of the account per trade.

• 20 trades a month: about 20 × 0.05% = 1% of the account a month in costs.
• Over a year of 240 trades: 1 − 0.9995 to the power 240 ≈ 11.3% of the account.

A strategy has to clear that hurdle before it adds anything. Higher trading frequency and tighter stops make the cost share larger. The guide to spreads and commissions explains how these costs are charged.

Deposits and withdrawals

Many growth charts mix trading returns with money added. That can make an account look as if it is compounding fast when most of the growth is deposits.

Worked example with regular deposits

Illustrative figures: start with £1,000 and add £100 at the end of each month for five years.

• At 0% return: £7,000, all of it your own deposits.
• At 1% a month: about £9,984, of which £7,000 is deposits and about £2,984 is growth.
• At 2% a month: about £14,686, of which £7,000 is deposits.

At modest rates, regular saving dominates the result for years. That is not a reason to aim for a higher rate; it is a reason to judge any track record on its time-weighted return, which strips out the effect of deposits and withdrawals.

Worked example with withdrawals

Withdrawals work the same way in reverse. Start with £5,000 and earn exactly 1% a month:

• Withdraw £50 a month: the balance stays at £5,000, because you take out exactly what is earned.
• Withdraw £75 a month: after five years the balance is about £2,958.

Anyone hoping to live off a trading account should run these numbers with a lower return and a few losing months before relying on it. The guide to how much money you need to start forex trading covers why small accounts and income goals sit badly together.

Where the big numbers come from

If the arithmetic is this unforgiving, why do so many people post huge returns?

• Short windows. A 40% month is possible with high risk. Annualising it, or compounding it in a chart, turns luck into a fantasy.
• Survivorship. The accounts that blew up are not posted. You see the winners from a large number of attempts, not the typical result.
• Demo or tiny accounts. A 300% gain on a small account says little about repeatability.
• Selling something. Signal groups, account management offers and courses often lead with return figures. The guide to forex scam red flags lists the patterns to watch for.
• Leaving out drawdowns. A strategy that made 100% in a year may have fallen 60% along the way.

The base rate is the useful anchor. Regulators in the EU and elsewhere have found that most retail CFD accounts lose money, which brokers must disclose, typically somewhere between about 60% and 90% depending on the firm. The reasons are covered in why most retail CFD traders lose. A plan built on 1% a day starts from an assumption far outside what the data supports.

Using the arithmetic sensibly

None of this means compounding is unimportant. It means the inputs have to be honest:

• Test with lower rates and losing periods. Run your figures at half your hoped-for return, and include a couple of losing months.
• Think in risk, not targets. Decide your risk per trade from your account size and drawdown tolerance, then accept whatever return the strategy produces.
• Track compound results, net of costs and deposits. A trading journal makes this straightforward.
• Watch the psychological pull of targets. A monthly goal encourages overtrading when you are behind and complacency when you are ahead, as the guide to trading psychology discusses.

Common mistakes

• Treating a monthly target as a plan. A target says nothing about how the risk is managed.
• Multiplying instead of compounding, or the reverse. 10% a month is not 120% a year; compounded, it is about 214%. Equally, 12% a year is not 1% a month compounded; that would be about 12.7%.
• Ignoring volatility drag. The average monthly return overstates the compound growth of a volatile account.
• Counting deposits as performance. Growth from new money is not a trading return.
• Forgetting costs. Spread, commission and swaps compound against you on every trade.
• Extrapolating a good month. A short sample says very little about the long-run rate.

Frequently asked questions

Is 1% a day realistic in forex?

No. Compounded over about 250 trading days, 1% a day multiplies an account roughly 12 times in a year, and over five years about 250,000 times. Daily trading results vary widely, losing days and losing streaks are normal, and most retail CFD accounts lose money. Treat any claim of a consistent 1% a day as a warning sign.

How do I calculate compound growth?

Multiply the starting balance by (1 + r) to the power n, where r is the return per period as a decimal and n is the number of periods. For example, £1,000 at 2% a month for 12 months is 1,000 × 1.02 to the power 12 ≈ £1,268. The compounding calculator does this and can add regular deposits or withdrawals.

How long does it take to double an account?

At a steady compound rate, the rule of 72 gives a quick estimate: 72 divided by the percentage return per period. At 1% a month that is about 72 months, close to the exact 69.7. Real trading returns are uneven, so actual doubling time is unpredictable and an account can shrink instead.

What is an average monthly return in forex?

There is no reliable average to quote, and averages of trader returns are dominated by the large share of accounts that lose money. Regulators and broker disclosures show that most retail CFD accounts lose money. Rather than aiming for a monthly figure, it is more useful to measure your own compound results over a large number of trades after costs.

Why does my account grow more slowly than my average return suggests?

Because of volatility drag and costs. A gain followed by an equal percentage loss leaves you behind: +10% then −10% is −1%. The larger the swings, the larger the gap between the average monthly return and the compound growth rate, and trading costs widen it further.

Does compounding work with withdrawals?

It works on whatever stays in the account. If you withdraw everything you earn, the balance stays flat and nothing compounds. Withdraw more than you earn and the balance shrinks, which is why income plans should be tested with lower returns and losing months.
