Step 2: Add Your Products
Common products are pre-filled to get you started. For each product, enter the name, cost per unit (price per pad, tampon, cup, etc.), how many units you use per period cycle, and the product's lifespan in years (0 for disposable items).
Step 3: Customize Your List
Use the "Add Another Product" button to include more options. Remove products you don't use with the × button. You can compare as many products as you like.
Step 4: Calculate & Compare
Click the "Calculate & Compare Costs" button to see detailed results. The comparison table shows costs per year, 5 years, 10 years, and over your lifetime, with visual bars to highlight the most affordable options.
🩸 Understanding Period Product Costs
The Financial Impact of Menstruation
Menstruation is not just a health reality for billions of people — it's also a significant financial expense that adds up over a lifetime. Research shows that the average person who menstruates will spend thousands of dollars on period products over their reproductive years. The type of product you choose dramatically affects your total lifetime cost, with reusable options offering substantial savings.
Disposable vs. Reusable: The Cost Difference
Disposable pads and tampons are the most commonly used products, but they are also the most expensive over time since they must be repurchased every single cycle. A menstrual cup, while having a higher upfront cost of $20-$40, can last up to 10 years, potentially saving hundreds of dollars. Period underwear typically costs more initially but can last 2-5 years, offering significant mid-term savings.
Beyond Cost: Other Factors to Consider
While cost is an important factor, there are other considerations when choosing period products. These include environmental impact (reusable products generate significantly less waste), comfort and fit, convenience (especially when traveling or at work/school), health considerations (such as toxic shock syndrome risk with tampons), and personal preference. Our calculator focuses on the financial aspect, but we encourage you to consider all factors when making your choice.
♻️ Environmental Impact
Disposable pads and tampons generate over 200,000 tonnes of waste annually in the US alone. Switching to reusable products can eliminate this waste completely over your lifetime.
💰 Average Savings
Switching from disposable pads/tampons to a menstrual cup can save $1,500-$2,500 over a lifetime. Period underwear can save $1,000-$2,000 compared to disposables.
🌍 Global Access
Period poverty affects millions worldwide who cannot afford menstrual products. Understanding costs and exploring reusable options can help make menstruation more affordable and accessible.
📈 Price Trends
Period product prices have risen with inflation. Our calculator uses current prices you enter, so you can update costs as prices change and see the real long-term impact.
Frequently Asked Questions (FAQ)
How much does the average person spend on period products in a lifetime?
Estimates vary widely, but the average person who menstruates can spend between $5,000 and $8,000 on disposable period products over their reproductive lifetime (typically 35-45 years). This includes pads, tampons, and panty liners. People who use exclusively reusable products like menstrual cups or period underwear can reduce lifetime costs to $500-$1,500, saving thousands of dollars.
What is the cheapest period product option overall?
Based on typical pricing, the menstrual cup is generally the most cost-effective option over time. Although the upfront cost is $20-$40, a quality cup can last 5-10 years, bringing the annual cost to just $2-$8 per year. Period underwear is the next most affordable reusable option. However, the cheapest option for you depends on your specific usage patterns, which is why our calculator lets you input your own numbers for accurate comparison.
How many periods does the average person have in a lifetime?
The average person who menstruates has approximately 450-480 periods over their lifetime. This is based on starting menstruation around age 12-13 and reaching menopause around age 50-52. With an average cycle length of 28 days, that's about 13 periods per year for roughly 35-40 years. Our calculator defaults to 13 periods per year over 40 years, but you can adjust these numbers to match your personal circumstances.
How long does a menstrual cup last?
High-quality menstrual cups typically last between 5 and 10 years when properly cared for. Medical-grade silicone cups are durable, non-porous, and resistant to bacteria when cleaned according to instructions. The FDA recommends replacing menstrual cups approximately every year, but many brands suggest they can last much longer. Our calculator uses 10 years as the default lifespan for menstrual cups, but you can adjust this in the entry field to match your specific product's recommendations.
How long does period underwear last?
Period underwear typically lasts between 6 months and 2 years with regular use and proper care, depending on the brand and quality. The lifespan depends on how frequently they are worn, washed, and the quality of the absorbent layers. Higher-end brands with better construction can last 2-5 years. Most manufacturers recommend replacing period underwear when you notice reduced absorbency, odor retention, or fabric wear. Our calculator defaults to 2 years for period underwear, but you can customize this.
How many pads or tampons does a person use per cycle?
The number of pads or tampons used per cycle varies widely based on flow intensity. On average, a person uses 10-20 disposable products per cycle. A typical period lasts 4-7 days, with heavier flow days requiring more frequent changes (every 3-4 hours). Light flow days may only require 2-3 products per day. For tampons, it's essential to change them every 4-8 hours to reduce the risk of toxic shock syndrome (TSS). Our default values are 12 pads or 14 tampons per cycle, but you should adjust based on your personal usage.
Can I save money by combining different period products?
Absolutely! Many people use a combination of products to optimize both cost and comfort. For example, using a menstrual cup on heavy days and period underwear as backup or on light days can be a cost-effective strategy. Some people use disposable products when traveling or for convenience and reusable products at home. Our calculator allows you to add each product separately and compare the total combined cost against using a single product type exclusively.
Are there tax benefits or subsidies for period products?
As of recent years, an increasing number of states and countries have eliminated the "tampon tax" (sales tax on menstrual products). In the US, over 20 states have exempted period products from sales tax. Some programs also provide free period products in schools, public buildings, and community centers. Flexible Spending Accounts (FSAs) and Health Savings Accounts (HSAs) in the US can be used to purchase period products with pre-tax dollars. This calculator does not account for tax savings, so your actual costs may be slightly lower if you can use pre-tax dollars or live in a tax-exempt jurisdiction.
Do reusable period products really pay for themselves?
Yes, reusable period products almost always pay for themselves compared to disposable options. A menstrual cup costing $30 typically pays for itself within 3-6 months compared to buying disposable tampons or pads. Period underwear sets costing $30-$50 per pair (typically needing 3-6 pairs for a full cycle) can pay for themselves within 6-12 months. Over a 40-year menstruating lifetime, the savings from switching to reusables can be $3,000-$6,000 or more, depending on your usage patterns and product choices.
Does the calculator account for inflation?
This calculator uses current prices that you enter and does not automatically account for inflation. Period product prices generally rise with inflation over time, so your actual long-term costs may be higher than estimated. To get a more conservative estimate, you may want to increase your cost-per-unit values by 1-2% per year or use current prices and understand that the results represent costs in today's dollars. The calculator is designed as a comparative tool to help you understand the relative cost differences between product types.
