Why these calculators exist
Most trading losses at the retail level aren't the result of a bad strategy — they come from incorrectly sized positions, misunderstood pip values, and funding costs that quietly compound over time. These tools are built to remove the arithmetic from trading decisions so you can focus on what actually matters. They cover every calculation you're likely to need from idea to execution to post-trade review.
Position & Risk
What it does: Takes your account balance, the percentage you're willing to risk on a single trade, and your stop-loss distance in pips. Returns the exact lot size you should trade.
Why it matters: Probably the most misused tool in retail trading. Most beginners pick a round number of lots and hope for the best. This calculator forces you to define your risk first, then size accordingly — which is how professionals do it.
Example: £10,000 account, 1% risk, 30-pip stop on GBP/USD → 0.33 lots.
Open calculator →What it does: Enter your entry price, stop-loss, and take-profit. The calculator returns your risk-to-reward ratio and the expected dollar gain or loss at your specified position size.
Why it matters: Trading with a ratio below 1:1.5 consistently is difficult to make profitable. This tool makes it quick to verify before you enter whether a trade setup actually makes mathematical sense.
Example: Entry 1.2800, stop 1.2770, target 1.2860 → ratio 2:1, £330 potential gain at 1 lot.
Open calculator →What it does: Shows how much you need to gain to recover from a given percentage loss. Also calculates your account value after a sequence of losing trades.
Why it matters: The mathematics of drawdown are counterintuitive. A 50% loss requires a 100% gain to get back to breakeven. Most traders underestimate recovery difficulty — this tool removes the optimism bias.
Example: 30% drawdown on £5,000 account → need 43% gain on remaining £3,500 to recover.
Open calculator →What it does: Converts your risk parameters into pound-per-point stakes for spread betting accounts, which use different sizing units than standard forex lots.
Why it matters: UK traders using spread betting accounts need this because the lot-based logic from MT4/MT5 doesn't directly apply. Confusing the two sizing methods is a common source of unintended over-exposure.
Example: £500 risk, 40-point stop on FTSE 100 → £12.50 per point stake.
Open calculator →Price & Market Analysis
What it does: Calculates daily, weekly, or monthly support and resistance levels using yesterday's high, low, and close. Supports Classic, Woodie, Camarilla, and Fibonacci pivot methods.
Why it matters: Floor traders used pivot points before most software existed, and they still work because enough participants reference the same levels. Useful as a starting framework for identifying where price is likely to pause or reverse.
Example: EUR/USD previous day H:1.0920 L:1.0860 C:1.0895 → PP: 1.0892, R1: 1.0924, S1: 1.0860.
Open calculator →What it does: Enter a swing high and swing low to generate retracement levels (23.6%, 38.2%, 50%, 61.8%, 78.6%) and extension levels (127.2%, 161.8%, 261.8%) automatically.
Why it matters: Fibonacci levels are self-fulfilling to a degree — because so many traders and algorithms reference the same ratios, price often reacts at them. They're most reliable when they align with other support/resistance structures.
Example: Swing from 1.0800 to 1.1000 → 61.8% retracement at 1.0876.
Open calculator →What it does: Converts between percentage returns and dollar amounts in both directions — useful for setting realistic targets and understanding what percentage gain you need after a loss.
Why it matters: Quick mental arithmetic on percentages leads to errors. This removes the friction of doing the maths mid-trade.
Example: 20% gain on £8,000 = £1,600 profit.
Open calculator →Currency & Pip Calculations
What it does: Calculates the monetary value of one pip in your account's base currency for any currency pair at any lot size. Accounts for cross-currency pairs where the calculation isn't straightforward.
Why it matters: On EUR/USD with a USD account, one pip on 1 standard lot = $10. On USD/JPY, it's different. On exotic pairs, it varies significantly. Knowing your exact pip value before placing a trade prevents a lot of surprises.
Example: 1 mini lot (0.1) on GBP/USD with GBP account → £0.714 per pip at 1.4 GBP/USD rate.
Open calculator →What it does: Live currency conversion across all major and most minor pairs. Shows the mid-market rate (no spread added), useful as a reference when comparing broker quotes.
Why it matters: Brokers always add a spread to the mid-market rate. Knowing the mid-market rate gives you a baseline to measure how much a broker is charging you on conversions.
Example: £5,000 converted at mid-market → $6,350 at 1.2700.
Open calculator →What it does: Enter your entry price, exit price, lot size, and pair to calculate exact profit or loss in your account currency. Accounts for pair-specific pip values automatically.
Why it matters: Useful for post-trade analysis and for verifying your broker's P&L calculation matches your own expectation.
Example: Long 0.5 lots EUR/USD from 1.0800 to 1.0850 → $250 profit.
Open calculator →Funding Costs
What it does: Calculates the overnight financing cost or credit for holding a position beyond the daily rollover, using the current swap rates for your pair and account type.
Why it matters: Traders holding positions for several days often forget about swap charges until they appear on their statement. On some pairs and directions, swaps can be positive (you receive, rather than pay). On others — especially against carry trade direction — they erode profitability significantly over time.
Example: Short AUD/USD 1 lot held 5 days at swap rate of -3.2 pips/day → -$16 total financing cost.
Open calculator →What it does: Shows the total monthly rebate you'd earn based on your monthly trading volume and the rebate rate per lot. Useful for comparing brokers' cashback programmes.
Why it matters: Active traders processing 50+ lots per month should take rebate programmes seriously. At $1 per lot rebate, that's $600/year on 50 lots/month — genuinely significant compared to the difference in spread between brokers.
Example: 40 lots/month at $2.50 rebate → $100/month, $1,200/year returned.
Open calculator →Long-Term & Performance
What it does: Projects how an account grows over time when profits are reinvested at a consistent percentage return. Adjustable for monthly or annual compounding periods.
Why it matters: Compounding works both ways — it grows profits exponentially but also means drawdowns compound against you. This calculator is useful for setting realistic multi-year performance expectations without the optimism bias.
Example: £5,000 at 3% monthly for 36 months → £14,563 without withdrawals.
Open calculator →What it does: Calculates Compound Annual Growth Rate between two values or dates. Useful for evaluating long-term account performance on a consistent annualised basis.
Why it matters: A strategy that returns 150% in three years sounds impressive, but its CAGR is only ~36% — which is how you should compare it against other strategies or benchmarks.
Example: Account from £8,000 to £19,500 over 3 years → CAGR of 34.5%.
Open calculator →A note on using these tools effectively
Calculators are only as useful as the inputs you give them. The most common mistake is using round numbers for stop-loss distances rather than placing stops at technically meaningful levels and then calculating the appropriate position size. Always determine where your stop should go based on the chart first, then use the Position Size Calculator to figure out how many lots to trade at that stop distance.
Swap rates change periodically — brokers adjust them based on interbank rates. If you run a carry trade or hold positions overnight regularly, check your broker's current swap schedule directly rather than relying on cached data in any third-party tool.
None of these calculators make trading decisions for you. They handle the arithmetic so you can focus on the analysis. The quality of your inputs determines the quality of the output — garbage in, garbage out applies here exactly as it does everywhere else.
