Consecutive Loss Calculator and Simulator

This consecutive loss calculator shows how a chosen losing streak changes account capital. It deducts a percentage of the remaining balance or a fixed rupee loss on each trade, then shows the gain needed to recover. Its odds assume equal win and loss chances with each outcome independent of the others. Months To Recover assumes a fixed return. These are scenarios, and the recovery outputs are invalid if capital reaches zero.

Choose percentage losses or fixed rupee losses

Starting Capital is the balance before the streak. Risk Per Trade (%) is applied to the remaining balance after each loss. Number of Consecutive Losses sets the length of the scenario. Fixed Loss Per Trade (₹) overrides percentage mode whenever it is positive. Leave that fixed-loss field at zero if you want a reducing-balance calculation.

In percentage mode, each rupee loss becomes smaller as the balance falls. The compact formula is starting capital × (1 − risk fraction) raised to the number of losses. In fixed mode, the same rupee amount is subtracted each time, with the displayed balance floored at zero. The percentage field does not add another deduction on top of a positive fixed loss.

CME’s risk-control lesson illustrates the reducing-balance approach and explains that a percentage recovery must be larger than the percentage fall. Our examples below use invented account values, so they describe the model without implying a real trader’s result.

How many losses in a row can your account take?

There is no single number. It depends on how much you risk on each trade and on where you personally stop. In percentage mode the account never reaches exactly zero, because each loss is a share of what is left. So the useful question is how many losses it takes to reach a limit you have chosen, such as a 20% drawdown (a fall from the highest balance), a prop-firm loss limit or your own pause rule.

To find that number with the calculator, enter your starting capital and risk percentage, then raise the number of consecutive losses until Total Loss Percent reaches your limit. Leave Fixed Loss Per Trade at zero. For a fixed rupee loss, enter the amount instead and the streak length that uses up your limit is the limit divided by the loss.

A made-up example: at 2% risk, 11 straight losses leave the account 19.93% lower, which is just under a 20% limit. The twelfth loss takes it to 21.53%. So a 20% limit is crossed on the twelfth loss in that scenario. Costs and slippage are not included.

Worked example: follow the shrinking balance

Assume Starting Capital ₹1,00,000, Risk Per Trade 2%, Number of Consecutive Losses 3 and Fixed Loss Per Trade ₹0. These are illustrative inputs, including the chosen risk percentage. The calculator applies each percentage loss before calculating the next one.

The unrounded final balance is ₹1,00,000 × 0.98 × 0.98 × 0.98 = ₹94,119.20. Final Capital displays ₹94,119. The tool then calculates Total Loss as ₹1,00,000 − ₹94,119 = ₹5,881, giving Total Loss Percent of 5.88%. This is why multiplying 2% by the streak length does not match the percentage-mode result.

Trades Breakdown shows rounded balances along the path. For a short streak it lists each stage. For a longer streak it shortens the display, so it should not be mistaken for a full downloadable trade record. The underlying loop retains its running precision between losses.

Compare the same example with a fixed loss

Keep the illustrative account and streak length, but enter ₹2,000 in Fixed Loss Per Trade. The model now subtracts ₹2,000 each time, so final capital is ₹1,00,000 − 3 × ₹2,000 = ₹94,000. Total loss is ₹6,000, or 6%. Both examples start with the same first loss; later losses differ because only percentage mode reduces the next rupee amount.

A fixed loss becomes a larger share of capital as the balance shrinks. A percentage scenario assumes that the position can be adjusted to maintain the chosen fraction. In live contracts, whole-lot restrictions may prevent exact adjustment. The Nifty sizing calculator explains that rounding issue for an index contract.

Recovery is measured from what remains

Recovery Needed is the lost amount divided by remaining capital, expressed as a percentage. Using the rounded percentage-mode result, ₹5,881 ÷ ₹94,119 × 100 = 6.25% after rounding. On the fixed-loss example, ₹6,000 ÷ ₹94,000 × 100 = 6.38%. The recovery denominator is smaller than the starting account.

As a separate made-up arithmetic check, reducing ₹1,00,000 to ₹50,000 is a 50% loss. Returning from ₹50,000 to ₹1,00,000 requires a 100% gain. A gain and loss of the same percentage do not cancel because they apply to different balances.

If the balance reaches zero, percentage recovery from that balance is not finite. The current tool prints a finite Recovery Needed value and zero Months To Recover in that case. Those outputs cannot describe recovery from a depleted account. Additional capital would be a new cash contribution, not a trading return on the zero balance.

Losses to drawdown: a quick table

The table below runs the calculator's percentage mode for three risk levels and three streak lengths. Every row starts from the same idea: each loss is the stated share of the remaining balance. The risk levels are examples to show how the maths scales, not recommendations.

Read the last column carefully. A fall of about 18% needs a gain of about 22% to get back, and a fall of about 40% needs about 67%. The gap widens quickly because the recovery is earned on a smaller balance. CME Group's risk-control course makes the same point in its table of gains needed to make up for losses.

The maximum drawdown calculator measures the same kind of fall on a real series of balances, and the drawdown glossary entry explains the terms.

The Probability card describes one assumed block

The tool hardcodes a 50% loss chance on each independent trade. In the illustrative three-loss scenario, the printed Probability is 0.5 × 0.5 × 0.5 × 100 = 12.5%. That is the chance that one specified block contains only losses under the assumption. There is no field for your win rate or total number of trades.

OpenStax’s independence explanation says independent events do not change each other’s probabilities and their joint probability is multiplied. That mathematical condition is an assumption here. The calculator does not test whether your losses cluster, whether your setup has changed or whether trade outcomes are independent.

A run appearing somewhere inside a longer trading record is a different question from all losses in one specified block. The Probability output cannot answer that wider question without a total-trade horizon and an appropriate run model. It also does not mean a winner is due after the losses you entered.

Consecutive losses and prop firm limits

Funded-account and challenge rules often limit losses in a way that differs from simple percentage maths. Two common ideas are static and trailing drawdown. Rules differ from one firm to another, so read the exact definitions on the firm's own page before you plan around them.

• Static limit. The floor is fixed from the starting balance. In a made-up example with ₹1,00,000 and a 10% loss limit, the floor stays at ₹90,000.
• Trailing limit. The floor rises as the account's highest balance rises. If the same account first reaches ₹1,10,000, a floor 10% below that peak would sit at ₹99,000, so the room for losses shrinks as you win.
• Fixed-rupee risk. Many traders risk a fixed amount on a challenge account. With ₹2,000 per loss, five losses in a row total ₹10,000, which reaches a 10% limit on the example account.

In percentage mode the rupee loss shrinks with each loss, so it takes more losses to reach a given limit than it does in fixed-rupee mode. Use the Fixed Loss Per Trade field to match a firm that measures from the starting balance. The prop firm drawdown calculator and the trailing drawdown guide cover those rules in more detail.

Months To Recover is an assumed growth schedule

Months To Recover uses a fixed hypothetical 3% gain each month, compounded from the remaining balance, and rounds up to a whole month. There is no field to set your own monthly rate. The value does not account for extra losing months, withdrawals, costs or deposits, and it is not a deadline by which an account should recover.

Use the balance and loss outputs as scenario arithmetic. To review actual results, compare them with your own logged outcomes, planned stops, costs and mistakes. The expectancy page concerns the average result across winning and losing trades. The risk-of-ruin page addresses a different probability model; neither replaces the assumptions missing here.

Is 2% risk per trade safe?

No number is safe for everyone, and this page does not recommend one. The tables only show what a streak does at different risk levels. In the table above, ten losses in a row at 1% risk lowers the account by 9.56%. At 2% the fall is 18.29%. At 5% it is 40.13%.

Whether those falls are acceptable depends on your capital, your costs, your emotions and your rules. Decide in advance the drawdown at which you stop and review. Then use the calculator to see how many losses at your chosen risk it would take to get there. The position size guide shows how to turn a risk limit into a quantity, and the losing streak guide covers what to do when the run is real.

How likely is a losing streak?

The Probability card assumes each trade has a 50% chance of losing and that trades are independent. Under that assumption, five losses in a row in one specified block of five trades is 3.125%. Real trading records do not follow a fixed 50% coin toss, so treat this figure as an illustration of how fast chances fall, not as a forecast of your streaks.

A longer record almost always contains some run of losses, even for a strategy that works. To count the streaks in your own history, use the trading streak tracker. To see how an edge and a risk size combine, try the risk of ruin calculator.

Fixed-rupee risk versus percentage risk after a losing streak

With fixed-rupee risk, every loss is the same amount, so the account falls in a straight line and the gain needed to recover rises faster near the end. With percentage risk, each loss is a little smaller than the last, so the fall slows down. The catch is that percentage risk needs you to shrink your quantity as the account shrinks. That is hard with whole lots on index contracts, so the calculator's percentage figures are a simplified picture.
