Wraps and tortillas are a convenient base for quick meals, but their iron content varies widely depending on the grain, flour type, and what you tuck inside. This Wrap Iron Calculator estimates the total iron in your wrap — including common iron-boosting fillings like spinach, black beans, and ground beef — in just a few clicks.
Whether you are tracking iron for general wellness, managing anemia, or planning plant-based meals, this tool lets you choose the wrap type and size, add typical fillings, and instantly see your total in milligrams and as a percentage of the 18 mg Daily Value. The step-by-step calculation also shows exactly how the numbers are derived.
Start by selecting a wrap type and size, enter how many wraps you are eating, tick any add-ins, then press Calculate. The quick-fill presets are handy for estimating popular burrito and wrap combinations.

How to Use This Calculator
Start by selecting the wrap type that matches your tortilla: flour, whole wheat, corn, spinach, tomato basil, multi-grain, low-carb, or gluten-free. Then choose the size — small (6 in), medium (8 in), large (10 in), or burrito (12 in) — and enter the number of wraps you plan to eat, from 1 to 20. If you added fillings, tick each checkbox that applies; the calculator multiplies every filling's iron contribution by the number of wraps. Press Calculate iron, and the result panel updates with the total iron in milligrams plus the percentage of the 18 mg Daily Value used on food labels.
The three quick-fill presets at the top — Hearty beef burrito, Veggie bean wrap, and Chicken power wrap — load realistic combinations so you can see how the tool works in one click. Feel free to edit any field after choosing a preset. Use Reset to return everything to its default state.
How the Iron Estimate Works
Each wrap type has a baseline iron value for an 8-inch (medium) tortilla, drawn from typical enriched flour, whole-grain, and vegetable-tortilla nutrition data. The size multipliers scale that baseline: small 6-inch wraps use ×0.7, large 10-inch wraps use ×1.4, and burrito-size 12-inch wraps use ×2.0. This linear scaling is an approximation — a larger tortilla has more flour and therefore more iron, but brand-to-brand variation remains significant.
Add-in iron values are based on common portion sizes: raw spinach at 1 cup, cooked black beans at ½ cup, ground beef at 3 oz, and so on. For each selected add-in, the tool multiplies the portion value by the number of wraps, adds all add-in contributions together, and finally adds the wrap iron to get the total. Dividing that total by 18 mg gives the Daily Value percentage shown in the main result.
Quick Reference: Iron in Wraps & Fillings
| Item | Portion | Iron (mg) |
|---|---|---|
| Whole wheat tortilla (8 in) | 1 tortilla | 1.3 |
| Spinach tortilla (8 in) | 1 tortilla | 1.7 |
| Flour tortilla (8 in) | 1 tortilla | 1.0 |
| Corn tortilla (8 in) | 1 tortilla | 0.7 |
| Raw spinach | 1 cup | 0.8 |
| Black beans, cooked | ½ cup | 1.8 |
| Ground beef, cooked | 3 oz | 2.5 |
| Grilled chicken breast | 3 oz | 0.9 |
| Roasted turkey breast | 3 oz | 1.0 |
| Large egg | 1 egg | 0.6 |
| Cheddar cheese | 1 oz | 0.2 |
Portions reflect common serving sizes compiled from USDA FoodData Central and the NIH Office of Dietary Supplements iron fact sheet.
Worked Examples
Example 1 — Spinach and bean wrap. One large spinach tortilla contains 2.4 mg of iron. Adding ½ cup black beans (1.8 mg) and 1 cup raw spinach (0.8 mg) brings the total to 2.4 + 1.8 + 0.8 = 5.0 mg, which is about 28% of the Daily Value. This makes a solid plant-based lunch.
Example 2 — Two beef burritos. Each burrito-size whole wheat tortilla has 2.6 mg of iron. With ground beef (2.5 mg) and cheese (0.2 mg) inside, one burrito totals 5.3 mg. Eating two means the wrap base contributes 5.2 mg, the add-ins contribute (2.5 + 0.2) × 2 = 5.4 mg, and the combined total is 10.6 mg — about 59% of the Daily Value.
Tips for Getting Accurate Estimates
- Check the nutrition label on your tortilla package whenever possible. Many commercial tortillas are enriched with iron, and the label value will be more precise than the average used here.
- Portion sizes matter. A generous half-cup of beans contains more iron than a level half-cup, so use measuring cups or a kitchen scale for consistent tracking.
- Iron from animal sources such as beef, turkey, and chicken is absorbed more efficiently than non-heme iron from plants. Pair plant-based wraps with vitamin C — salsa, citrus juice, bell peppers, or tomatoes — to improve absorption.
- If you are tracking iron for anemia or a medical condition, remember that the 18 mg DV is a general reference for adults. Individual needs vary by age, sex, and health status, so consult a healthcare professional for personalized guidance.
Frequently Asked Questions
Are these iron values exact? No. Real-world tortillas vary because of flour fortification, ingredient ratios, and cooking techniques. The values in this tool are averaged from standard nutrition references, so treat them as reasonable estimates rather than lab results.
Why is the Daily Value set at 18 mg? In the United States, 18 mg is the reference Daily Value for iron used on Nutrition Facts labels for adults and children aged four and older. More information is available in the NIH Office of Dietary Supplements iron fact sheet.
Can I use this calculator for meal prep? Yes. Enter one wrap and its fillings, then multiply by the number of servings you are preparing. Because the tool also accepts multiple wraps directly, you can quickly estimate a full day or a week of wrap-based meals.
What if my wrap is a different size? If your tortilla falls between the listed sizes, choose the closest option, or use a kitchen scale and the nutrition label on the package for a more precise estimate.
