# Trading Calculators: Liquidation, Funding, Position Size and More

> Free calculators for liquidation price, funding, position size, profit and loss, break-even, average-down, risk/reward, leverage and perpetual options profit.

Everstrike's [Tools](https://everstrike.io/app/tools) page has nine free calculators. They work without an account.

| Calculator | What it works out |
| - | - |
| [Liquidation price](https://everstrike.io/app/tools/liquidation-price-calculator) | Where a position would be liquidated |
| [Funding](https://everstrike.io/app/tools/funding-calculator) | What holding a position will cost or earn in funding |
| [Position size](https://everstrike.io/app/tools/position-size-calculator) | A position size from your stop distance and risk |
| [Profit / loss](https://everstrike.io/app/tools/pnl-calculator) | The result of a trade |
| [Break-even](https://everstrike.io/app/tools/break-even-calculator) | The price you need after funding |
| [Average down](https://everstrike.io/app/tools/average-down-calculator) | Your new entry after adding to a position |
| [Risk / reward](https://everstrike.io/app/tools/risk-reward-calculator) | Whether a trade's target justifies its stop |
| [Leverage](https://everstrike.io/app/tools/leverage-calculator) | Exposure, and the distance to liquidation |
| [Perpetual options profit](https://everstrike.io/app/tools/options-profit-calculator) | The profit on a perpetual option position |

## Per-market funding calculator

The funding calculator also has a page per market, for example `/app/tools/funding-calculator/eth`, filled in with that market's live hourly funding rate.

## How they work

The calculators use Everstrike's rules: for example a maintenance margin of 0.5% of the position on perpetual futures, and funding settled every hour. They're estimates for planning a trade. The exact values for an open position are in its panel. See [Managing a Position](https://docs.everstrike.io/trading/managing-a-position.md).

> [!TIP]
>
> Before a leveraged trade, check the liquidation price calculator. Your stop loss should sit well before the liquidation price.
