• How accurate are the results?
While we use industry-standard formulas and regularly update our calculators, results should be considered estimates only.
Important limitations:
- • Financial calculators use current rates but market conditions change
- • Health calculators provide general estimates, not medical advice
- • Crypto calculators estimate based on historical data
For critical decisions (like financial or medical), consult a qualified professional.
