The answer

The answer: how far price must move to recover all costs

If you searched for a break-even pips calculator, the one thing you want to know is how far price must move to recover exactly what you paid in costs. The answer is this: the break-even move equals your total cost expressed in the account currency, divided by the position’s monetary value per pip (or per point). If total cost is 1,450 JPY and value per pip is 1,000 JPY, break-even is 1.45 pips. Only once price has moved 1.45 pips in your favour does the trade sit at zero, neither profit nor loss.

Translate that required move into a price and you have the break-even price: entry price plus the required move for a long, entry price minus it for a short. The share of that total cost against the move you are actually aiming for is the cost ratio, and it climbs sharply as the target shrinks, even though the fixed cost never changes. This article calculates break-even pips, break-even price and cost ratio end to end from a single illustrative example. How each cost component is built (constructing spread, commission and swap) is left to its own article; for the wider map, the complete guide to trading-cost calculation gives you the overview.

Assumptions and terms

Assumptions and terms: break-even pips, break-even price, cost ratio and friction score

Let us settle four words up front. Break-even pips (the required move) are the pips (or points) price must travel in your favour to recover the total cost you paid. Break-even price is that required move applied to the entry price as an actual price level, with the add-or-subtract direction reversed for long versus short. Cost ratio is the share of your intended profit (the monetary value of the target move) that total cost consumes, expressed as a percentage. And the friction score is a relative indicator shown by SG Group’s Trade Cost Calculator that lets you gauge, at a glance, how heavy that cost burden is.

The “total cost” used here is the sum of spread, commission and swap or overnight financing, all converted into the account currency. Constructing each piece is not the subject of this article: converting the spread from pips into money is covered in the article on turning spread pips into trading cost, one-way versus round-trip and fixed or notional-percentage fees in the article on folding commission into all-in cost, and swap across holding days and triple-day rollover in the article on swap and overnight financing. This article receives the total cost those pieces produce and concentrates on translating it into break-even and cost ratio.

One more assumption matters: the monetary value per pip. This is how much your profit or loss changes, in the account currency, when price moves one pip on a position such as one standard lot, and it varies with the instrument, lot size and account currency. When the profit-and-loss currency differs from the account currency, conversion becomes a separate stage; in this article’s illustrative example the P&L currency equals the account currency (JPY), so no conversion is applied.

General equation

The unit-aware general equation

First the symbolic form; the next section substitutes numbers. Dropping units is where people lose the thread, so each term carries its unit.

Here the “price unit (price / pip)” is what one pip equals in price terms. For a JPY pair whose smallest increment is the second decimal place, one pip is typically 0.01; for many dollar-straight pairs quoted to the fourth decimal place, one pip is typically 0.0001, but this varies by instrument and account, so always confirm it against your trading conditions. When the denominator of cost ratio, the intended gross profit, is zero or negative (target move of zero or less), cost ratio cannot be calculated. And when the P&L currency differs from the account currency, keep the order: express both total cost and value per pip in the same account currency before dividing.

Illustrative example

Working one consistent illustrative example

From here to the end of the article we reuse the following illustrative educational data. These are not real prices, contract specifications or fills.

Divide that total cost of 1,450 JPY by the value per pip of 1,000 JPY and break-even pips are 1,450 ÷ 1,000 = 1.45 pips. In other words, a favourable move of 1.45 pips recovers spread, commission and swap exactly. The swap here is paid (negative), so it works to widen the required move. Had it been a positive (received) swap, the required move would narrow by that amount, but take care not to treat positive swap as permanent income.

Break-even price

Long and short break-even price

Now convert the 1.45-pip required move into a price. Since the price unit is 0.01, 1.45 pips = 0.0145. A long adds it to the entry; a short subtracts it. The long break-even price is 150.000 + 0.0145 = 150.0145, and the short is 150.000 − 0.0145 = 149.9855. The required move (pips) is the same 1.45 pips for both; only whether you add it to or subtract it from the entry differs. The figure below shows the long and short break-even prices sitting symmetrically around the entry. Beyond colour, they are distinguished by direction (left = short, right = long) and by numeric labels.

Note that commission and swap are charged in money, not in price. The break-even prices in the figure are the result of converting those monetary costs into a required move (pips) via the value per pip, then applying it to the price. In a real account, the required move can shift depending on whether commission is built into the fill or charged separately, and on when and how many times swap is applied (including triple days). Because the fill price itself also moves with slippage, read the break-even price as a static reference, not a guarantee of execution at the stated level. How to fold slippage into effective cost is covered in the article on slippage and effective trading cost.

Two break-evens

What separates spread-only from all-in break-even

Break-even comes at two levels depending on how much you count. Spread-only break-even is the move needed to recover just the quoted spread, 0.8 pips (= 800 JPY ÷ 1,000 JPY) in our example. All-in break-even adds commission and swap on top, widening it to 1.45 pips in the same example. Look only at the spread and it is easy to believe “a single pip recovers this,” but add commission and holding cost and the required move stretches by roughly 1.8 times. The figure below shows that gap as a stacked bar.

Which break-even to use depends on your trading style. For intraday scalping or day trading that does not cross the daily rollover, traders often look at a spread-plus-commission break-even on the assumption that no swap applies; for swing trades held overnight, they evaluate on an all-in break-even that includes swap for the days held. How turnover and holding days change the required move and the weight of recovery is explored in the article on comparing cost by trading style.

Cost ratio

Cost ratio and the break-even ladder: the shorter the target, the heavier the load

Break-even pips give the minimum move needed to recover cost, but in practice you want to compare that against your target move. That is what cost ratio does: the share of intended gross profit (the monetary value of the target move) that total cost consumes. Against the fixed cost of 1,450 JPY, a 10-pip target (gross profit = 10,000 JPY) gives a cost ratio of 1,450 ÷ 10,000 × 100 = 14.5%. Net at target is 10,000 − 1,450 = 8,550 JPY. The key point is that cost is fixed while shortening the target move shrinks only the denominator. The break-even ladder below lines up the cost ratio for target moves from 3 to 100 pips against the same 1,450 JPY fixed cost.

On a trade aiming for 3 pips, cost eats roughly half of the profit target (48.3%). At 10 pips it is 14.5%, and at 100 pips it falls to 1.45%. This is why short-term trading is said to carry a higher cost ratio: the fixed cost does not change, yet the target move (the denominator) shrinks, so the ratio jumps. There is no universal pass mark for cost ratio. What you can tolerate depends on your strategy’s expectancy, win rate and turnover, so read it as a relative comparison between like-for-like conditions, or against your own target move, rather than as an absolute threshold.

Breaking down profit

The gross to cost to net waterfall

Cost ratio and net become intuitive when you see them as a flow of money. The waterfall below shows the flow from the 10,000 JPY gross profit at a 10-pip target, subtracting spread 800 JPY, commission 500 JPY and swap 150 JPY in turn, to a net of 8,550 JPY. Gross profit, cost, net, and the loss region that remains if the target is missed, all sit continuously in one figure. This is not a diagram that guarantees profit; it is an educational breakdown of the order in which cost eats into profit.

If price falls short of the 10-pip target and moves only 1 pip, for instance, gross profit stops at 1,000 JPY, below the total cost of 1,450 JPY, so this trade is negative on a net basis (a loss of −450 JPY). The relationship is clear: net only turns positive once the move exceeds the 1.45-pip break-even. The cost band (red) and net profit (green) are labelled with signs (+/−) and text as well as colour, so that favourable versus adverse can be read without relying on colour vision.

Friction score

How to read the friction score

SG Group’s Trade Cost Calculator includes a relative display called the friction score that pulls break-even pips and cost ratio together. It is an indicator for gauging, at a glance, how much cost a trade is carrying, and it is handy when comparing several sets of trading conditions. This article, however, invents no pass marks or thresholds of its own, because the friction score’s exact formula, bands and thresholds are defined in the tool itself. Confirm the precise meaning, including whether a lower or a higher number is better, against the display and explanation in the current Trade Cost Calculator.

This article’s role is to make the foundations of the friction score, the required move (break-even pips) and cost ratio against the target move, something you can follow by hand. Rather than memorising a friction-score number, it helps to understand the relationships: for the same target move, a smaller total cost makes recovery lighter; for the same total cost, a shorter target move makes cost ratio heavier. With those in mind, you can read why the tool’s friction score rises or falls. If you want to compare brokers or account types fairly, the approach of ranking on total cost and spread sensitivity is covered in the article on comparing broker and account trading costs.

Mini learning aid

Break-even mini calculator

The mini calculator below takes an entry price, direction, total cost, value per pip, price unit and target move, and returns break-even pips, break-even price, cost ratio and an illustrative net at target. It makes no pass/fail or “safe” judgement. All calculation happens in your browser, and your inputs are neither sent nor stored anywhere. First, so it is readable even with JavaScript disabled, here is a static worked table for this article’s illustrative example (entry 150.000, long, total cost 1,450 JPY, 1,000 JPY per pip, price unit 0.01, target 10 pips).

This calculation is a simplified learning aid based on SG Group’s Trade Cost Calculator. It receives total cost as an already-summed amount and does not break out spread, commission and swap, apply currency conversion, count one-way versus round-trip charges, or handle tax, execution slippage or stop-out. In the real tool, results can differ depending on those input fields, on P&L-to-account-currency conversion and on rounding. To estimate with the official input fields, enter your own conditions in the free SG Group Trade Cost Calculator.

Check it free

How to check it in the free calculator, and where the higher tiers earn their place

Once the idea of required move and cost ratio has landed, the next step is to put your own conditions into numbers. The free Trade Cost Calculator lets you check, for a single trade, one-way and round-trip trading cost, an estimated break-even including spread, commission and swap, break-even pips and price, value per pip, cost ratio, friction score, swap reflecting the holding days, and sharing, all as estimates from your input conditions. Exact input names and ranges can change, so check the latest on the plans page.

For simply checking the break-even and cost ratio of a single condition, as covered here, the free version is enough. When you reach the point of wanting to line up several conditions for the same trade, how the required move changes if the spread widens, if you switch commission mode, or if you extend the holding days, that sensitivity and the break-even ladder bring Pro’s in-session advanced analysis into view. Pro is a comparison of conditions, not a market forecast or an entry recommendation. Further, when you want to keep cost-condition changes and swap movements as an ongoing ledger and turn them into reports, Premium’s saving and ledger features apply. Feature names, scope and pricing can change, so confirm the latest on the current service and plan pages before use. Starting free and considering a higher tier only where a one-off calculation cannot solve the problem keeps things sensible. Note, too, that reverse-solving required margin or lot size and stop-out is not the primary domain of the Trade Cost Calculator; that belongs to the Lot Size Calculator.

Avoid

Common mistakes and how to avoid them

Mistakes around break-even and cost ratio tend to fall into a few patterns. If any of these ring true, that is where to start reviewing.

• Judging break-even from the spread alone: forgetting to add commission and swap and underestimating the required move. In our example the true figure is 1.45 pips, not 0.8.
• Double-counting commission: adding a round-turn fee twice as if it were one-way, or confusing one-way with round-trip. Decide the charge count first.
• Getting the swap sign wrong: mistaking a paid (negative) swap for a received (positive) one and underestimating the required move. Do not fix positive swap as permanent income.
• Ignoring cost against the target move: looking only at break-even pips and missing how cost ratio spikes when the target is short.
• Skipping the P&L-to-account-currency conversion: dividing without converting when the currencies differ, so value per pip is off. Keep conversion as an independent stage.
• Mistaking the break-even price for a guaranteed fill: fills move with slippage and gaps. The break-even price is a static reference.

Summary

Summary: the answer to the main question, and your next step

The move required to recover all costs, the break-even pips, is found simply by dividing total cost in the account currency by the monetary value per pip. In our illustrative example that is 1,450 JPY ÷ 1,000 JPY = 1.45 pips. Apply it to the price and the long break-even is 150.0145 and the short is 149.9855. Recovery that would take only 0.8 pips on the spread alone widens to 1.45 pips once commission and swap are included. And cost ratio against the target move grows heavier as the target shortens, from about 48.3% at 3 pips to 1.45% at 100 pips. The friction score is SG Group’s relative display that pulls these together, and its exact definition is confirmed in the tool.

In practice, (1) sum spread, commission and swap into a total cost, (2) divide by value per pip to get break-even pips, (3) turn it into a break-even price with the long or short direction, (4) check cost ratio and net against the target move, and (5) put your own conditions into numbers with the free calculator. Follow that order and you will not confuse the required move with the cost burden. The natural next step is the swap calculation that bears on trades held overnight, which sharpens the precision of your total cost.
