Pregnancy Caffeine Limit Calculator
Obstetric guidance commonly advises keeping caffeine under about 200 milligrams per day in pregnancy. Caffeine content varies enormously by drink, brand, and serving, so this calculator asks you to enter the actual milligrams for each drink plus any extra from tea, soft drinks, chocolate, or supplements. It totals them, compares the total to your daily limit, and shows how many milligrams remain. The 200 milligram limit is the editable default. It is a tracking aid for general information, not medical advice; follow your own provider's guidance.
Caffeine total formula
Total caffeine = drink 1 + drink 2 + drink 3 + other
Remaining = daily limit - total caffeine
Status = over limit if total > limit, otherwise within limit
Percent of limit = total / limit * 100
The default daily limit is 200 milligrams, the figure commonly advised in pregnancy. Enter the actual caffeine for each item from its label or a reliable reference.

Pregnancy caffeine: frequently asked questions
How much caffeine is considered safe in pregnancy?
Obstetric guidance commonly advises keeping caffeine intake under about 200 milligrams per day during pregnancy. This calculator uses 200 milligrams as the default daily limit, which you can adjust if your provider recommends a different ceiling for your situation.
How does this calculator work?
You enter the caffeine in milligrams for each of up to three drinks plus any extra caffeine from other sources. It adds them up, compares the total to your daily limit, and shows how many milligrams remain. Because caffeine content varies widely by product and serving, you enter the actual amounts rather than relying on assumed values.
Why are caffeine amounts user-entered rather than preset?
The caffeine in coffee, tea, soft drinks, and energy drinks varies enormously with brewing, brand, and serving size. Presetting a single figure would mislead. Entering the caffeine from each product's label or a reliable reference gives a far more accurate daily total.
Does caffeine come from sources other than coffee?
Yes. Tea, many soft drinks, energy drinks, chocolate, and some medications and supplements contain caffeine. Use the extra-caffeine input to include these so your daily total reflects everything, not just coffee.
Is this calculator medical advice?
No. It adds up caffeine and compares it to a limit you set for general information. Individual recommendations may differ. Always follow the guidance of your own obstetric provider regarding caffeine and other intake during pregnancy.
