Trading Calculators

Pick a calculator to size a position, price a pip, check the margin a trade needs or see how a run of losses could affect your account before you place an order.

This page collects the 13 calculators and tools we publish for forex and CFD trading. Some answer a single question about one trade, such as how many lots fit a set risk or what a pip is worth on a given pair. Others look at the whole account: how leverage and margin interact, how returns compound, how likely a strategy is to hit a drawdown limit. A few, like paper trading, bar replay and backtesting, let you practice or test ideas without placing live orders. Where a tool needs an exchange rate, it starts from a live quote, and you can change the inputs to match your own case.

How the calculators are grouped

The tools fall into two groups. The risk and size group covers the position size calculator, margin, leverage, risk of ruin and a consistency calculator built for prop firm rules. The prices and growth group covers pip value, profit, compounding and a currency converter. A practical order for planning a single trade is to decide how much of the account you are willing to lose, set the stop distance, run the position size, and then confirm the pip value with the pip calculator. After that, the margin calculator shows how much of your balance the trade ties up at your leverage. The simulators, paper trading, bar replay and backtesting pages sit apart from these. They are for rehearsing a method on past or simulated prices, not for working out the numbers on one order.

What goes into the numbers

Each calculator does plain arithmetic on the inputs you give it: account currency, pair, lot size, stop distance, leverage, win rate and so on. Rates are prefilled from live data so the conversion between quote currency and account currency is close to current, but the result is only as accurate as what you enter. Brokers set their own contract sizes, margin rates and rounding, and regulators cap leverage differently by region, so a figure here can differ from what your platform shows. When it does, your broker’s contract specifications are the reference. These tools are not scored and not ranked, and no brand chooses or pays for what appears on this page. Our scores for brokers and prop firms are a separate process, described in our methodology. For prop firm accounts, the consistency calculator checks a profit record against the kind of single day limit many challenges apply.

Limits to keep in mind

A calculator shows the math of a plan, not how a trade will play out. Spreads widen, orders slip, prices gap over weekends and news, and overnight swap charges add up; most of these are not part of a simple position size or profit result. The risk of ruin calculator assumes your win rate and payoff stay fixed, which real results rarely do. Backtests and bar replay sessions look cleaner than live trading because you know the chart already exists. Trading forex, CFDs, futures and crypto carries a real risk of losing money, and leverage makes losses larger as well as gains. Nothing on this page is financial advice. Use the numbers to set limits you can live with, then check them against your broker’s terms.

Which calculator should I use first?

For a single trade, start with the position size calculator. Enter your account balance, the share of it you are willing to risk and your stop distance, and it returns a lot size. Then check the pip value and the margin required so you know what each move is worth and how much of your balance the trade will tie up.

Why does my broker show a different pip value or margin?

Brokers set their own contract sizes, margin rates and rounding, and leverage limits vary by regulator and region. The calculators use standard formulas and live rates, so small gaps are normal. If the difference is large, check that the pair, lot size, leverage and account currency match, then treat your broker's contract specifications as the reference.

Are the rates in the calculators live?

The calculators are prefilled with live rates so the currency conversion starts close to the current market. Prices move constantly, so the figure you see may differ slightly from your platform at the moment you trade. You can change the inputs yourself if you want to plan around a specific entry price.

Can these tools help with prop firm challenge rules?

Yes, in part. The consistency calculator checks whether a set of daily profits fits a typical single day profit limit, and the risk of ruin and position size calculators help you keep losses inside a drawdown cap. Each firm writes its own rules, so read the exact terms of your challenge before relying on any result.
