The accuracy depends entirely on the numbers you input. Our calculator simply multiplies your per-instance cost or time by frequency over different periods. For money calculations, we assume costs remain constant (no inflation). For the most accurate personal results, use your actual spending data and update the calculator periodically.

Currently, our calculator doesn't have a save feature as it operates entirely in your browser. However, you can take screenshots of your results or note them down. We're working on adding account features in the future that will allow saving and tracking progress over time.

These are based on average costs for common purchases and experiences (like vacations, gadgets, or car payments) and average time investments for learning new skills or completing projects. They're meant to provide perspective rather than exact equivalents, as actual costs and time requirements can vary by location and personal circumstances.

No, for simplicity, our calculator uses the current cost you input without adjusting for inflation over the 5-year projection. This means actual future costs might be higher if prices rise. However, this conservative approach can make the results even more compelling when considering habit changes.

Currently, you can only calculate one habit at a time. However, you can run calculations for different habits separately and add the results manually if you want to see combined totals. We're planning to add multi-habit tracking in a future update.

We convert all time to hours for consistency. Weekly: frequency × time per instance × weeks. Monthly: weekly × 4.33 (average weeks/month). Yearly: monthly × 12. 5-year: yearly × 5. For daily habits, we assume 365 days/year unless you specify otherwise in frequency.

No. All calculations happen in your browser, and we don't store any of your input data. We respect your privacy, and there's no tracking beyond basic anonymous analytics about site usage (like most websites).

While health impacts are important, they're highly individual and require medical expertise to estimate accurately. We focus on quantifiable time and money metrics that apply universally. That said, we may add optional health modules in the future.

Absolutely! While designed for personal habits, the calculator works for any recurring expense or time investment. Many small business owners find it helpful for analyzing operational costs like supplies, software subscriptions, or meeting times.

We recommend recalculating whenever your habits change significantly, or at least annually. Costs and time commitments often creep up gradually, so regular check-ins (like during New Year's resolutions or financial reviews) can help maintain awareness.
