Pip Value Calculator

Calculate the dollar value of one pip for any forex pair and lot size. The number that determines your dollar profit and loss per pip move — and the one you should size your risk against, not the pip count itself.

Position Size Calculator

Work backwards from the dollar risk you've decided to take per trade to the exact lot size that loses precisely that amount if your stop hits. The honest way to size — risk first, lot size derived.

Risk-to-Reward Ratio Calculator

How many of these trades do you need to win to break even? A 1:2 R:R means you only need to be right 34% of the time. A 1:1 needs 50%. Most beginners overestimate the win rate they can actually hit — this shows the math.

Compounding Calculator

What does steady 5% per month compound to over a year? Two years? This calculator runs the math honestly — including the realistic effect of drawdowns reducing the compound period.

Drawdown Recovery Calculator

A 50% drawdown requires a 100% gain to break even. A 75% drawdown requires 300%. This calculator shows the asymmetry of recovery — and why protecting against deep drawdowns matters more than chasing returns.

Live Trading Sessions Clock

Which forex sessions are open right now? The London/New York overlap is when most pairs move — knowing your local time relative to session open and close shifts how you read every chart.

Forex Calculator FAQ

What's a pip and why is it different on JPY pairs?

A pip is the standard price move unit in forex. For most pairs it's 0.0001 (the fourth decimal). For JPY pairs the price is quoted with two decimals, so a pip is 0.01. The dollar value of each pip depends on your lot size and the quote currency.

How do I calculate position size in lots?

Divide your dollar risk (account balance × risk %) by (stop loss in pips × pip value per lot). The result is the lot size that loses exactly your intended risk if the stop hits. The calculator above does this automatically.

What's a "good" risk-reward ratio?

It depends on your win rate. 1:1 needs 50% win rate to break even. 1:2 needs 34%. 1:3 needs 25%. There's no universal "good" — what matters is whether your actual win rate beats the break-even number for your typical R:R.

Is 5% per month realistic for forex?

It's possible but rare. Most consistent retail traders average 1–3% per month over multi-year periods. 5%+ months happen but typically come with months of losses too. Compounding calculators that assume steady high returns mislead.

Why does a drawdown need an asymmetric gain to recover?

If you lose 50% you have half your account. To get back to 100% from 50% requires doubling — a 100% gain. The math is unavoidable: recovery_pct = 100 / (100 - drawdown_pct) − 1. The deeper the drawdown, the more disproportionate the recovery needed.

Do these calculators work for prop firm accounts?

Yes — prop firms use the same pip values and lot sizes as retail. The differences are in the rules (daily drawdown limits, max total drawdown, profit targets), not the math. Use the position size calculator with the prop firm's allowed risk %.
