Built for Real Traders
Whether you're sizing a spot position, calculating a futures liquidation price, or planning a long-term DCA strategy — every calculator here is purpose-built for real trading decisions. No filler. Calculators have no paywall.
Proper position sizing is the single most important habit a trader can build. Our crypto risk calculator lets you define your account size, set a stop-loss level, and instantly see the correct position size so you never over-leverage a trade. Suitable for spot, margin, and futures trading across Bitcoin, Ethereum, and any altcoin.
Dollar-cost averaging removes the emotion from crypto investing. Our DCA calculator helps you plan recurring buys, visualize your average entry price over time, and understand how compounding works in your favor during bear markets. Whether you invest weekly or monthly, DCA is how long-term holders build positions without chasing tops.
Futures trading is unforgiving — one bad leverage call and you're liquidated. Our liquidation price calculator shows exactly where your position will be force-closed based on your entry, leverage, and margin. Pair it with the stop-loss / take-profit calculator to set levels that protect your capital before you open the trade.
All calculations run entirely in your browser. DennTech never transmits your trade data, account size, or portfolio details to any server. There are no accounts and no cookies tied to your calculator inputs. Risk math should be free. The live stock scanner is a separate paid product for traders who want the real-time desk.
