Coffee lovers know the joy of a perfectly brewed cup, but it’s also important to know how much caffeine you’re actually consuming. That’s where our Caffeine Intake Calculator comes in. It helps you log your drinks, measure your daily caffeine, and compare it against safe health guidelines.
Whether you’re a student sipping cold brew, a busy professional living on americanos, or a barista experimenting with espresso shots, this tool gives you a clear picture of your daily caffeine load.
This tool is part of our Coffee Calculators series designed to give you accurate, practical answers for everyday brewing questions.

How We Compute
- Per-mL drinks (drip, pour-over, French press, cold brew, moka): Total mg = strength (mg/mL) × volume (mL).
- Espresso drinks (espresso, cappuccino, latte, flat white, americano, mocha, ristretto, lungo): Total mg = strength (mg/shot) × number of shots.
- Daily total = sum of all items; mg/kg = daily total ÷ body weight in kg (we auto-convert from lb).
- Largest single dose = biggest per-item caffeine amount you added (optionally time-stamped).
- Guidelines: Adults ≤400 mg/day; single doses ≤200 mg. Pregnancy/trying/breastfeeding: <200 mg/day. Teens: ≤100 mg/day and ≤3 mg/kg/day. Children <12: avoid caffeine.
- Actual caffeine varies by bean, roast, grind, ratio, and brew method. If symptoms (palpitations, anxiety, insomnia) occur, reduce intake and consider consulting a clinician.
Why Monitor Your Caffeine Intake?
Caffeine can boost alertness, mood, and even physical performance. But too much may cause:
- Jitters and anxiety
- Insomnia or disrupted sleep
- Rapid heartbeat or palpitations
- Upset stomach
Tracking helps you enjoy your coffee responsibly while avoiding unpleasant side effects.
Safe Daily Caffeine Limits
According to health experts:
- Healthy adults: Up to 400 mg/day is considered safe (≈ 4 cups of brewed coffee).
- Pregnant, trying, or breastfeeding: Keep intake below 200 mg/day.
- Teens (12–18 years): Limit to 100 mg/day or ≤ 3 mg per kg of body weight.
- Children under 12: Best to avoid caffeine entirely.
👉 These numbers come from FDA, EFSA, ACOG, and the American Academy of Pediatrics (see references).

How much caffeine should pregnant women have?
Health experts recommend limiting caffeine to less than 200 mg per day during pregnancy and breastfeeding.
Can teenagers drink coffee?
Yes, but in moderation. Teens aged 12–18 should keep caffeine below 100 mg/day or 3 mg per kilogram of body weight. Energy drinks and espresso shots can easily exceed this.

A standard latte usually contains 63 mg of caffeine per shot of espresso. A tall latte with two shots has about 126 mg. (See our full guide)
How do I know how much caffeine is in my coffee?
Caffeine levels depend on the brewing method, bean type, and serving size. Use the Caffeine Intake Calculator above to input your drink type and volume for an estimate.
Is decaf coffee caffeine-free?
No. Decaf coffee still contains about 1–2 mg per 240 mL cup, which is much less than regular coffee.
What happens if I drink too much caffeine?
Excess intake may cause jitters, anxiety, digestive upset, trouble sleeping, and rapid heart rate. In rare cases, very high doses can be dangerous.
