Position Size Calculator
Calculate the exact position size for any trade based on your account balance, risk percentage, and stop loss distance. The most important calculator in trading.

Calculate R:R ratio and breakeven win rate for any trade setup.
Breakeven = 1 ÷ (1 + R:R)
Pip Value Calculator
Calculate the value of one pip for any lot size and currency pair.
Compound Growth Calculator
Project your account growth with compound returns over time.
Lot Size Calculator
Convert your risk amount into the correct lot size for forex trading.
Why Every Trader Needs These Calculators
Risk management is the foundation of profitable trading. Before entering any trade, professional traders calculate their exact position size, verify the risk-to-reward ratio meets their minimum threshold, and confirm their total account exposure is within safe limits. These five calculators automate that process so you can focus on finding high-quality setups.
The Position Size Calculator is the most important tool on this page. It ensures you never risk more than your predetermined percentage on any single trade. Combined with Quantum Algo's automatic order block and FVG detection — which gives you precise stop loss levels — you can calculate exact position sizes in seconds.
The Compound Growth Calculator shows why consistent, small returns compound into extraordinary results over time. A trader making 5% monthly on a $5,000 account reaches $8,979 in 12 months and $16,127 in 24 months — all through the power of compounding.

Sizing and risk maths should never be the reason a good setup goes wrong. These calculators handle the numbers so you can focus on reading the chart — position size from your stop distance, risk and reward in R, pip and lot values, and more. Each one is built around the fixed-percentage risk approach that keeps traders in the game.
Use them with your plan
The most valuable habit is calculating your position size before every trade, from your account size, your fixed risk percentage, and the structural stop distance. Doing the maths in advance removes the in-the-moment temptation to over-size — the single most common account-killer. Pair these calculators with the risk rules in your trading plan.
Frequently asked questions
How do I calculate my position size?
Position size = (account × risk %) ÷ stop distance. Decide a fixed small risk percentage, measure your stop distance to the structural invalidation, and the calculator returns the size — keeping your dollar risk constant on every trade regardless of stop width.
Get precise stop levels automatically
Quantum Algo marks exact order block and FVG boundaries on your chart — giving you the precise stop loss levels these calculators need.
