Add what you actually had
Copy the caffeine amount from the label, cafe menu, or manufacturer listing when possible. Coffee and tea can vary widely, so the tool does not pretend one cup always contains the same amount. Your entries stay in this browser tab and are not uploaded.
ACOG advises keeping daily caffeine intake below 200 mg during pregnancy.
Add a common drink
NHS estimates. Use the figure on the label or menu instead when you have one, since coffee-shop drinks in particular vary.

Add the caffeine amount from each label, menu, or manufacturer listing.
The reference point depends on your country
The U.S., UK, Australia, Ireland, and Canada do not all use the same wording or number. Select where you live in the calculator and open the linked authority if you need the full guidance. Advice from your own doctor, midwife, or dietitian takes priority when it is more specific.
| Country | Daily reference | Authority |
|---|---|---|
| United States | 200 mg | American College of Obstetricians and Gynecologists |
| United Kingdom | 200 mg | NHS |
| Canada | 300 mg | Health Canada |
| Australia | 200 mg | Pregnancy, Birth and Baby |
| Ireland | 200 mg | Health Service Executive |
Caffeine can hide outside coffee
Tea, cola, energy drinks, chocolate, guarana, yerba mate, pre-workout products, supplements, and some cold, flu, or pain medicines may add to the day. Read the whole label. Ask a doctor or pharmacist before using a medicine or supplement during pregnancy.
Check the wording on a product labelHow much caffeine is actually in things
If the label does not give a number, these are the NHS estimates for common foods and drinks. They are a starting point for the calculator above, not a measurement of the specific cup in your hand.
| Food or drink | Estimated caffeine | What changes it |
|---|---|---|
| Instant coffee | 100 mg per cup | NHS notes filter coffee and coffee bought from coffee shops can contain more. |
| Tea, black or green | 75 mg per cup | Brewing time changes the result, so a strong long-brewed cup sits higher. |
| Energy drink | 80 mg per 250 ml can | Larger cans and pre-workout products can be far higher. Check the label. |
| Cola | 40 mg per can | Diet and regular versions can differ, and some colas carry more. |
| Plain dark chocolate | Less than 25 mg per 50 g bar | Counts toward the day, though it is rarely what pushes a total over. |
| Plain milk chocolate | Less than 10 mg per 50 g bar | The smallest common source on this list. |
Estimates from NHS pregnancy guidance on foods to avoid.
Against a 200 mg reference, two cups of instant coffee will use most of the day on their own. That is the practical reason people are surprised: the total goes not from one big drink but from a coffee, a tea in the afternoon, and a cola with dinner.
Coffee-shop coffee is the hard one
The NHS figure of 100 mg is for a cup of instant coffee, and the NHS says plainly that filter coffee and coffee bought from coffee shops can contain more. Serving words are not measurements. A cup at home, a cafe cup, a bottle, and a large energy drink can all contain different amounts, and the FDA says caffeine content varies among products and sizes.
Most large chains publish caffeine content per drink and per size. When you can find the published number for the exact drink and size, use it. When you cannot, enter your best estimate and keep the uncertainty visible rather than assuming the lowest figure.
Herbal tea is a separate question
Herbal teas are usually caffeine free, so they do not add to the total above. That does not make them unlimited. NHS guidance is to drink no more than 4 cups of herbal tea a day during pregnancy, and to avoid teas containing liquorice root.
The reason given is honest uncertainty rather than a known harm: there is not much research on the effects of drinking herbal teas in pregnancy, so the advice is to limit rather than to rely on them as a free swap for coffee.
If you went over or feel unwell
A daily total is not an exposure assessment or diagnosis. It cannot tell you whether a pregnancy was affected. Contact your doctor, midwife, pharmacist, poison service, or urgent service as appropriate if you are worried about the amount, a concentrated caffeine product, a medicine, or symptoms.
Pregnancy caffeine questions
How much caffeine can I have during pregnancy?
Current guidance differs by country. ACOG advises less than 200 mg a day in the United States. The NHS, Australia's Pregnancy, Birth and Baby service, and Ireland's HSE use a 200 mg daily limit. Health Canada recommends a maximum of 300 mg a day.
What should I count toward my caffeine total?
Count every source you consume that day. This can include coffee, black or green tea, cola, energy drinks, chocolate, guarana, yerba mate, supplements, and some medicines. Check medicine use with a doctor or pharmacist during pregnancy.
Can this calculator know the caffeine in my coffee?
No. Caffeine varies with the beans, serving size, brewing method, brew time, and brand. Use the amount on the product label, cafe menu, or manufacturer's website when it is available. Treat a generic estimate as an estimate.
What if I logged more than the reference point?
The total cannot estimate risk or tell you whether a pregnancy was affected. Follow your clinician's advice and contact them if you are worried about your intake, symptoms, a medicine, or a concentrated caffeine product.
Keep the drink with the rest of your day
Ask Nouri about the exact drink or log it with your meals. The app keeps the product, serving, pregnancy week, and daily context together instead of reducing the question to coffee alone.
