The COC Upgrade Cost Calculator is a comprehensive tool designed to help Clash of Clans players plan and calculate upgrade costs for buildings, troops, heroes, and other game elements. It provides accurate cost calculations, time requirements, and resource planning to optimize your village progression strategy.

No account is required! All calculators work immediately without registration. Your data is saved locally in your browser, so you can start calculating right away. However, this means your saves are device-specific and won't sync across different browsers or devices.

Our calculators maintain 99.8% accuracy, verified against official game data. We continuously monitor Clash of Clans updates and adjust our calculations within 24-48 hours of any game changes. All costs, times, and requirements are sourced directly from official game files and community-verified data.

We update our calculators within 24-48 hours after each Clash of Clans game update. Major updates are usually processed within 12 hours, while minor balance changes may take up to 48 hours. We also perform weekly accuracy checks to ensure all data remains current.

Use the 'Save' button in any calculator to store your current setup locally. You can name your saves for easy identification and load them later using the 'Load' button. Saves include all your input values, selected options, and calculated results.

Yes! Use the 'Export' button to download your calculations in CSV format, perfect for spreadsheet analysis. You can also export individual calculator results or comprehensive reports including all your saved calculations and progress tracking data.

Bulk input allows you to process multiple items simultaneously. Select multiple buildings, troops, or upgrades using Ctrl+click (Cmd+click on Mac), then apply operations to all selected items at once. This feature saves significant time when planning large-scale upgrades.

Absolutely! All calculators are fully responsive and optimized for mobile phones and tablets. The interface automatically adapts to your screen size, and touch interactions are optimized for mobile use. For complex calculations, landscape mode is recommended.

All modern browsers are supported including Chrome, Firefox, Safari, and Edge. We recommend using the latest browser version for optimal performance. Internet Explorer is not supported. If you experience issues, try clearing your browser cache or using an incognito/private browsing window.

All your data is stored locally in your browser using HTML5 localStorage. This means your saves, preferences, and calculation history stay on your device and are not transmitted to our servers. Data persists between browser sessions but is device and browser-specific.

Differences usually occur due to: 1) Incorrect input values (double-check your current levels), 2) Recent game updates we haven't processed yet, 3) Special events or temporary boosts active in-game, 4) Town Hall level restrictions not accounted for. Verify your inputs first, then contact support if issues persist.
