Calculators that work without an account.
Three pieces of arithmetic every discretionary trader does, done right and done in the open: risk-to-reward and R-multiples, position size from the risk you accept, and how much room a prop-firm rule leaves you. No sign-up. The same maths runs inside Sage on your real trades.
The tools
Pick a number to get right.
- Free toolRisk/reward calculatorEnter entry, stop and target to get the risk-to-reward ratio, the R-multiple of any exit, the break-even win rate that ratio needs, and expectancy per trade. Free, no sign-up.Open the calculator →
- Free toolPosition size calculatorSize a trade from the money you are willing to lose: account balance, risk percent, stop distance and pip or point value give you units and lots. Forex, gold, indices and futures.Open the calculator →
- Free toolProp-firm drawdown calculatorHow much room does today leave you? Enter the account size, daily-loss and max-loss rules, static or trailing drawdown, and your P&L so far to see the losses that would end the challenge.Open the calculator →
The reasoning behind the numbers
- GuideRisk/reward ratio and R-multiples, explainedWhat a risk-to-reward ratio really tells you, how R-multiples make every trade comparable, the break-even win rate for any ratio, and why 'would 3R have paid?' needs the real price path to answer.
- GuidePosition sizing: size the trade from the risk, never the other way roundThe one formula that decides your survival: units = money at risk ÷ stop distance. Worked examples for forex, gold and indices, why fixed-fractional beats fixed lots, and how sizing interacts with prop-firm limits.
- GuideProp-firm challenge rules, explained the way they are measuredHow prop-firm challenge rules are actually measured — daily loss on equity, static vs trailing drawdown, minimum trading days, server-time resets — and how to track your distance to each limit before the next trade.
Stop calculating by hand. Record it.
In Sage every trade carries its R, its size and its distance to your prop-firm limits automatically — free, on your own data.
