Free Forex Trading Calculators and Tools
Every calculator on the site in one place: sizing, pip value, profit, margin, risk reward, compounding, drawdown, swap and a live session clock.
Rayner5 min read24 September 2026Forex trading calculators exist because the arithmetic of a trade is easy to get wrong in a hurry and expensive when you do. A position sized by feel rather than by stop distance is the most common reason a good strategy still loses money.
Every tool on this page is free, runs in your browser and needs no account. Start with position size if you are new, because it decides how much every other number matters.
These free forex trading calculators cover the arithmetic every trade needs: what a pip is worth, how large a position should be, what a move pays, how much margin it ties up, what the risk to reward ratio is, what a drawdown costs to recover, and what holding overnight charges. All of them run in the browser and nothing is stored.
Start here: sizing a trade
| Tool | What it answers |
|---|---|
| Lot size calculator | How many lots to trade, given the stop and the amount at risk |
| Pip value calculator | What one pip is worth at your size, on any instrument |
| Risk reward calculator | Whether the trade pays enough to be worth the risk |
These three run in order. Pip value feeds the lot size, and the lot size is only worth calculating once the stop and target are on the chart.
Working out the money
| Tool | What it answers |
|---|---|
| Profit calculator | What a move is worth in dollars, and what the stop would cost |
| Margin calculator | How much the position ties up, and the margin level left |
| Swap calculator | The overnight cost of holding, including the triple charge |
Looking at the account as a whole
| Tool | What it answers |
|---|---|
| Drawdown calculator | What a losing run costs, and the gain needed to recover it |
| Compound calculator | What a steady return builds to, and what one bad month removes |
These two belong together. Compounding shows the upside of consistency, and drawdown shows why protecting the downside matters more than chasing the upside.
Timing
| Tool | What it answers |
|---|---|
| Market hours clock | Which sessions are open right now, in your own time zone |
| Market hours converter | The four sessions written out for major cities |
| Economic calendar guide | How to read the week ahead and the releases that move prices |
Most of what happens in a currency chart happens in a few hours a day. The full timetable is in forex market hours.
Two calculators we already had
The pip value and lot size calculators were built before this hub and live at their own addresses, linked above. They are the two that matter most, so they were the first ones written and they are deliberately not duplicated here. Everything else on this page is new.
| Tool | Address |
|---|---|
| Pip value | /pip-value-calculator/ |
| Lot size and position sizing | /lot-size-calculator/ |
The order to use them in
- 01Find the setupEntry, stop and target on the chart, in that order.
- 02Check the ratioRisk reward calculator, before anything else is decided.
- 03Work out the pip valueFor the instrument and the size you are considering.
- 04Size the positionLot size calculator, from the stop distance and your risk per trade.
- 05Check the marginMargin calculator, to confirm the position fits comfortably.
- 06Count the cost of holdingSwap calculator, if the trade will be held for days.
Who each tool is for
| If you are | Start with |
|---|---|
| New to trading | Lot size, then pip value. Nothing else matters until sizing is right |
| Trading intraday | Risk reward and profit, because costs decide the outcome at short holding times |
| Swing trading | Swap and margin, since positions are held across rollovers and for longer |
| Trading a funded account | Drawdown, because the daily and overall limits are what end an account |
| Reviewing a strategy | Compound and drawdown together, for the full picture of a record |
A note on what these tools assume
Every calculator here assumes a US dollar account and standard contract sizes: 100,000 units of the base currency for a forex lot, and 100 ounces for gold. Brokers vary, and a few use different contract sizes on metals and indices, so the platform specification is always the final word.
None of the tools store anything or send data anywhere. They are arithmetic in the browser, provided for information rather than as financial advice. What they cannot tell you is whether a trade is a good idea, only what it costs and what it pays if it works.

Frequently Asked Questions
What forex calculators do I actually need?
Position size and pip value cover most of it. Risk reward, margin and swap matter as soon as trades are held longer or sized larger.
Are these calculators free?
Yes. They run in your browser, need no account, and store nothing.
What contract size do they use?
A standard lot of 100,000 units of the base currency for forex, and 100 ounces for gold. Check your broker specification if it differs.
Do the calculators include spread and commission?
No. They show the raw arithmetic of the price move. Costs reduce every result, and matter most on short trades.
Which calculator should a beginner start with?
The lot size calculator. Position size decides how much everything else matters, and it is the most common thing new traders get wrong.
Can I use these for gold and indices?
Gold is included throughout. Index contract sizes vary by broker, so use the platform specification for those.
Do you have an economic calendar?
We publish a guide to reading one rather than hosting a live feed, because the data comes from the agencies that publish it.
