Stock Averaging-Down Exit Simulator

How it works

This stock averaging-down exit simulator is not a one-line average-cost calculator. When you are underwater, it answers two practical questions: how much more cash do you have to add (average down) to pull the average near breakeven, and at what rebound from the market can you exit after that new average.

Averaging down is a weighted average: add the extra buy to your current cost basis, divide by the new quantity, and you get a new average price. Buying at the market never quite reaches the market—the average only approaches it. So this tool reverse-calculates the cash needed to bring the average down to market + a gap (1–15%), instead of promising a false "back to even" at the same print.

1. Enter quantity held, current average, and market price.
2. Enter an add-on buy amount and buy price to see the new average and mark-to-market P/L instantly.
3. Use the target exit % slider for an exit price from the new average, plus the rebound required from today's market.
4. Use the near-breakeven gap to reverse-calculate cash needed to get the average close to spot.
5. The canvas chart plots extra cash versus the falling average, with old average, market, and exit lines.
6. Copy result builds a paste-ready summary for notes or chat.

Frequently asked questions

How is this different from a basic average-cost calculator?

A basic tool only prints the new average. This page also does stock average-lowering math, reverse cash-to-near-breakeven, a crypto exit simulator style rebound target, and a graph so you can see how expensive "getting close to even" really is.

Why can't I average down all the way to the market price?

If the add-on buy price equals the target average, no finite cash solves the equation. You must aim at an average slightly above the market (the gap). The tighter the gap, the more cash you need—often many times your current position.

Does it work for both stocks and coins?

Yes. Use share counts or fractional coin quantities. Presets fill a stock averaging-down example and a crypto averaging-down example so you can see the curve immediately.

What is the exit percentage based on?

It is a target return from the new average after averaging down. Example: a new average of 46,667 with +10% exits near 51,333. If the market is 40,000, that still needs about a +28% rebound from spot.

Are my numbers saved?

The last quantity, average, market, and add-on cash are stored in localStorage on this browser only. There is no history list and no account sync.
