PRICE INTO PERSPECTIVE

Stock Profit & Loss

Turn an assumed price move into a dollar gain or loss.

01 · FLAGSHIP TOOL

Stock Scenario Calculator

How to use it: Enter the stock symbol, what one share costs, how many shares you have and how far you think the price may move. The calculator shows the new share price, the new value of all your shares and your possible profit or loss. Example: 20 shares bought at $250 cost $5,000; if the price rises 10% to $275, they become worth $5,500—a $500 gain.

Bull$275.00$500.00

What this result meansYou invested $5,000.00 at $250.00 per share. In this scenario, the price becomes $275.00 and 20 shares create a hypothetical gain of $500.00. It is an illustration, not a forecast.

EXAMPLE

20 shares at $250, with a 10% rise → $500 potential gain

How it works & assumptions

HOW TO USE IT

Enter a share price and share count. Choose up or down, then set a move in percent or dollars per share. The ticker is only a label.

Profit or loss = number of shares × (assumed future price − purchase price).

CHANGE ONE THING

Try a 20% move instead of 10%, then change the direction to down. Compare the dollar impact.

This models a long stock position. It excludes fees, taxes and dividends. Neither the assumed price nor execution is guaranteed.

ILLUSTRATIVE RESULTS

Total contributed$40,000.00

Illustrative growth$23,367.82

Illustrative ending value$63,367.82

What this result meansSee how starting capital and recurring month-end additions may compound. Uses a constant nominal annual rate divided by 12, monthly compounding and contributions at each month-end. Taxes, fees and volatility are omitted.

EXAMPLE

$10,000 + $250/month for 10 years at 7%, compounded monthly → About $63,368

How it works & assumptions

HOW TO USE IT

Enter your starting balance, monthly contribution, annual rate and years. Contributions are added at the end of each month; results update as you type.

Monthly rate = annual rate ÷ 12. Each month, the model applies growth, then adds your contribution.

CHANGE ONE THING

Try 20 years instead of 10. Keep everything else the same and see how the result changes.

A constant rate is a teaching assumption, not a forecast. Actual returns fluctuate. Fees, taxes and inflation are not included.

RISK BEFORE REWARD

Position Size

Compare a risk-based share count with your available capital.

03 · RISK CONTROL

Position Size

How to use it: Enter your account value, the percentage you are willing to risk, your planned buy price and your stop price. It estimates how many shares keep the possible loss near your chosen limit. Example: 1% of a $25,000 account is $250; with $3 at risk per share, the estimate is 83 shares.

Account sizeRisk per trade (%)Entry priceStop priceAvailable capital for this purchase

Financing assumption

Estimated share count83 shares

Maximum risk budget$250.00

Modeled loss at the entered stop$249.00

Position value$4,150.00

Gross exposure / account equity16.6%

What this result meansThe risk budget is a ceiling, not the expected loss. The modeled stop loss is shares × stop distance; the position value is separate and may be limited by available capital. Gaps and slippage can make the actual loss larger.

EXAMPLE

$25,000 account · 1% risk · $50 entry · $47 stop → 83 shares

How it works & assumptions

HOW TO USE IT

Enter account equity, a risk percentage, entry and stop prices, and available capital. Cash-only mode caps the estimate by what the entered capital can buy.

Risk budget = account equity × risk %. Risk-based shares = budget ÷ stop distance, rounded down; cash-only mode also applies the capital limit.

CHANGE ONE THING

Try a 0.5% risk budget instead of 1%. Notice how the share count and modeled loss change.

A stop is not a guaranteed exit price. Gaps and slippage can cause larger losses. The chosen risk percentage is an example, not a recommendation.
