How to calculate certified mail postage
To calculate certified mail postage, you'll need to follow these steps:
- Determine the weight of your mailpiece: Weigh your mailpiece using a scale to get its exact weight in ounces or grams.
- Determine the size of your mailpiece: Measure the length, width, and thickness of your mailpiece to determine its size. You can use a ruler or a measuring tape to do this.
- Check the mailpiece's dimensions: Compare your mailpiece's dimensions to the USPS's size standards for certified mail. If your mailpiece is larger than the maximum size allowed, you'll need to use a larger envelope or package.
- Calculate the postage: Use the USPS's postage calculator or consult the USPS's website to determine the postage cost for your certified mailpiece. You can also use the following formula:
Postage = (Weight x Rate per Ounce) + (Size-based Surcharge)
Where:
- Weight is the weight of your mailpiece in ounces
- Rate per Ounce is the current rate for certified mail (currently $3.80 per ounce)
- Size-based Surcharge is an additional fee for larger mailpieces (currently $0.21 for each additional ounce or fraction thereof)
For example, if your mailpiece weighs 2 ounces and is a standard letter size (up to 11.5 inches long, 6.125 inches wide, and 0.25 inches thick), the postage would be:
Postage = (2 oz x $3.80 per oz) + $0.00 (no size-based surcharge) = $7.60
- Add the certified mail fee: Certified mail requires an additional fee, which is currently $3.45 for each piece. Add this fee to your calculated postage:
Total Postage = $7.60 + $3.45 = $11.05
- Check for any additional fees: Depending on the type of certified mail you're using (e.g., return receipt requested), you may need to pay additional fees.
