Now 27 Tools: Compound Interest, Dividend Calculator, Minesweeper & Snake — All Separate

We listened to feedback: combined tools felt cramped. Today we're splitting two of our most popular combined tools into four dedicated standalone tools. ToolStand now has 27 free tools.

📈 Compound Interest Calculator → Now Standalone

The Compound Interest Calculator now focuses purely on compound interest — no dividend inputs cluttering the UI. Enter your initial amount, monthly contribution, interest rate, and years. Get instant results with line and stacked bar charts powered by Chart.js.

What changed: Removed dividend yield input and dividend results. The interface is cleaner, faster, and more focused. The classic formula with monthly/quarterly/annual compounding still works perfectly.

💰 Dividend Reinvestment Calculator — New

This is a brand new tool: Dividend Reinvestment Calculator. Designed specifically for dividend investors who want to see how yield, share price growth, and tax rates affect their portfolio over time.

Features: Dividend yield + share price growth simulation, monthly addition support, adjustable tax rate (set to 0 for tax-free accounts like ISA, 401k, TFSA), stacked breakdown chart showing invested vs dividends vs growth, and Year 1 income estimate.

💣 Minesweeper — 3 Difficulty Levels

Minesweeper is now a standalone game with 3 difficulty levels: Easy (9×9, 10 mines), Medium (16×16, 40 mines), and Hard (30×16, 99 mines). No more tab switching — just pure, focused minesweeping.

What's new: Difficulty selector, win detection with celebration message, long-press flagging on mobile, right-click flagging on desktop. The flood-fill reveal algorithm works flawlessly.

🐍 Snake Game — New Standalone

Snake Game now lives on its own page. Classic snake gameplay with canvas rendering, touch swipe controls, and a mobile D-pad for on-screen direction control.

Features: WASD and arrow key support, touch swipe detection, mobile D-pad, progressive speed increase, high score saved to localStorage, eyes on the snake head that follow movement direction, and a game-over overlay with final score.

Why The Split?

Combined tools are convenient but they come with trade-offs:

• SEO: A page titled "Minesweeper & Snake" ranks for neither as well as a page titled "Minesweeper" would. Now each tool has its own optimized title and description.
• Focus: Users searching for "compound interest calculator" don't want to see dividend inputs. Users searching for "snake game" don't want to tab-switch.
• Embeddability: Each embed is now purpose-built. A financial site embeds a dividend calculator. A gaming site embeds minesweeper. One tool per embed.
• Maintainability: Smaller, single-purpose files are easier to test, debug, and improve.
