What lot size should I use for a $1,000 account?

On a $1,000 account risking 1% ($10) with a 20-pip stop loss on a standard USD pair, the correct size is about 0.05 lots (5 micro lots). With a wider 50-pip stop it drops to about 0.02 lots. The exact figure always depends on your stop-loss distance, not just your balance.

What lot size for a $100 account?

At 1% risk ($1) with a 20-pip stop, the maths gives about 0.005 lots, which is below most brokers' 0.01 micro-lot minimum. In practice a $100 account often can't trade a standard pair within 1% risk, so you either accept higher risk per trade or trade a smaller-pip-value instrument. This is the main reason very small accounts are hard to grow.

What lot size for a $500 account?

About 0.025 lots at 1% risk ($5) with a 20-pip stop, or roughly 0.01 lots (the broker minimum) with a 50-pip stop. A $500 account can trade within sensible risk, but only in micro lots.

Does lot size depend on account size or stop loss?

Both. Your account size sets how much 1% is in dollars, and your stop-loss distance sets how many pips that risk is spread across. A bigger stop means a smaller lot size for the same risk. That's why there's no single 'lot size for a $1,000 account'; it changes with every trade's stop.

What Lot Size for a $1,000 Account? ($100 & $500 Too)

On a $1,000 account risking 1% ($10) with a 20-pip stop loss, the correct lot size is about 0.05 lots (five micro lots). For a $500 account it's around 0.025 lots, and for a $100 account roughly 0.005 lots, small enough that most brokers can't even place it.

The short answer There is no single "lot size for a $1,000 account." It depends on two things: how much you risk (1% is the standard) and how wide your stop loss is. The table below gives the exact lot size for the most common account sizes, but the real takeaway is the method, not the number.

Lot size by account size (at 1% risk)

This table assumes you're risking 1% of your account per trade on a standard USD pair like EUR/USD, where one pip is worth about $10 per standard lot. The two right-hand columns show how the lot size changes with your stop-loss distance.

Account size	Risk (1%)	Lot size · 20-pip stop	Lot size · 50-pip stop
$100	$1	0.005 *	0.002 *
$250	$2.50	0.012 *	0.005 *
$500	$5	0.025	0.01
$1,000	$10	0.05	0.02
$2,500	$25	0.125	0.05
$5,000	$50	0.25	0.10
$10,000	$100	0.50	0.20
$25,000	$250	1.25	0.50
$50,000	$500	2.50	1.00

* Below the 0.01 (micro) lot minimum at most brokers. See "the small-account trap" below. Figures are rounded estimates for a ~$10/pip standard pair; gold, indices and JPY pairs differ.

How to read the table (and adjust it for any trade)

The formula behind every row is simple:

Lot size = (Account × 1%) ÷ (Stop in pips × $10)

So for a $1,000 account with a 30-pip stop: $10 ÷ (30 × $10) = 0.033 lots. Change the stop and the lot size changes; that's why your account balance alone never gives you the answer. We cover the full method in how to calculate position size in forex.

The small-account trap (why $100 is so hard)

Look at the top rows again. A $100 account risking a sensible 1% can only "afford" about 0.005 lots on a 20-pip stop, but most brokers won't let you trade below 0.01 lots (one micro lot). That leaves a small-account trader with two bad options:

Trade the 0.01 minimum anyway, which on a 20-pip stop risks $2, or 2% of a $100 account. Now you're risking double the safe amount on every trade.
Widen the stop to make 0.01 lots "fit" 1% risk. But moving your stop to suit your position size is backwards, and usually means a worse trade.

This is the honest reason tiny accounts are so hard to grow: proper risk control and the broker's minimum lot size collide. It's not impossible, but it's why most experienced traders suggest starting with at least a few hundred dollars, or treating a $100 account as tuition, not a path to riches.

Rule of thumb

If your correct lot size comes out below 0.01, your account is too small to trade that setup at safe risk. Either pick trades with tighter stops, choose a lower-pip-value instrument, or build the account up first. Don't "solve" it by risking more.

Account size isn't the only input

Two more things shift the numbers above:

The instrument. Gold (XAU/USD), indices and oil have different point values than forex pairs, so the same account trades a very different lot size. Always size to the specific instrument.
Your risk %. The table uses 1%. If you (carefully) use 2%, every lot size doubles. We'd rarely suggest going higher, because small risk is what keeps a small account alive long enough to grow.
