One first-class stamp is required for a letter weighing one ounce. A first-class stamp costs $0.55 as of January 2019; each extra ounce costs $0.15. So, if you're mailing a 2-ounce letter, you'll need $0.70 in postage stamps. For letters up to 4 ounces, a first-class stamp will cost no more than $1.00.
The price of a first-class stamp varies by country and delivery method. Here are some average prices:
United States: $1.10 (first class) $1.45 (certified)
Canada: C$1.19 (regular) C$1.38 (express)
Mexico: 55 centavos de peso (peso) ($11.25 at current exchange rates). Note that because of fluctuating exchange rates, the currency converter on this page shows an approximate value.
Central America: from $1.09 (first class) to $1.39 (express)
South America: from $0.99 (first class) to $1.39 (express)
Europe: €1.06 (first class) €1.42 (express)
If you use a typical First-Class stamp with a value of 55 cents, it will take two stamps to mail a 1 ounce box and seven standard stamps to transport a 13-ounce item. Add 20 cents to the $1 base rate for each extra ounce for intermediate weights. For example, three stamps would be required to mail a 2-pound package.
The recommended minimum mailing weight is 0.5 ounces for most letters, but some post offices may require heavier mail. The maximum weight varies based on the post office location; generally, packages must weigh no more than 7 oz. APO/FPO addresses require special handling by the postal service. Check with your local post office to find out how much mail they can accept.
Stamps are sold in quantities of various sizes, from single stamps to large bundles called "bunches." If you have several items that need mailing, consider buying a bunch of 50 stamps at a time. Bundles are offered in different rates according to their quantity; for example, a bundle of 100 stamps is about half the price of a bundle of 200 stamps.
There are two types of postage stamps: national stamps and regional stamps. National stamps are valid throughout the United States, while regional stamps are valid only within a specific region or state.
One $0.50 first class rate stamp is required for a 6" x 9" envelope weighing up to 1 ounce. You'll have to pay $0.21 for each additional ounce. So, for a weight of 1 to 2 ounces, it will cost you $0.71. For 2 to 3 ounces, it will be $1.04. For more than 3 ounces, the price increases sharply - almost $1 for every additional ounce.
The correct answer is $0.70. Envelopes today are made from lightweight materials which allow them to be used for many purposes besides just mailing letters. Some envelopes are even designed to be reused after their contents are sent away with custom labels attached. Others may have adhesive strips on the back so you can attach coupons to them. Still others may be decorated with printable tags using advanced technology called ink-jet printing. Even when discarded, empty envelopes can be recycled.
The postage meter machine or "stamp machine" as it is often called, allows for one-touch automatic posting of letters. It also provides a limited number of letters for which it will accept payment. If you attempt to use all of the letters provided or if you go over the maximum payment limit, the rest of the letters will be returned to you.
You must choose between two options at the time you post a letter: cash or postal money order.
A one-ounce first class postal stamp costs $0.55 at the post office or $0.47 if purchased and printed online through Stamps.com. The price may vary depending on where you buy it from.
The cost of postage varies by weight and destination. If you're sending an envelope, the price includes writing and addressing two sides of regular paper. For heavier items such as boxes or bags, additional charges apply. Before you send anything important, check the postage rates for your destination to make sure you're getting a good deal.
What does postage cost? The actual price that you pay at the post office depends on how heavy your package is. Generally, prices range from $0.50 for a letter up to about $15 for a large package. There are also additional charges for priority mail, recorded delivery, insurance, etc. The following is a list of common weights and their associated postage rates:
Under 1 oz - $0.01 per oz over 1 oz but under 2 oz - 50c per oz over 2 oz
Books - $0.15 per volume of mailing material
Bags/Boxes - $0.10 per linear foot (of width plus height) of container space used
How many would you like to use? One lifetime stamp may be used to send a typical 1 oz letter. This will always be the same as the price of a first-class letter. You can use any combination of stamps that adds up to the $0.50 first class postage price for a regular letter at the current rate (at the time of this response).
Stamps can be spent by anyone who has access to postal funds. They can also be saved by collecting various issues of stamps. There are three types of collections: definitive, commemorative and special issue.
Definitive stamps are those that remain in general use over a long period of time. For example, Alexander Hamilton's portrait is still being printed on to stamps to this day. It is therefore a definitive stamp. Commemorative stamps commemorate people or events that have something in common. For example, there are stamps honoring Martin Luther King Jr., Rosa Parks and Abraham Lincoln. Special issue stamps are used to pay taxes or raise money for certain causes. Examples include the Christmas Stamp issued in 1965 to honor America's heritage of peace through gift-giving and the Vietnam Veterans' Memorial Stamp issued in 1971 to honor all servicemen and -women who died in war games or actual combat.
The United States Postal Service issues new stamps every month. They are available to buy online and at post offices and stamp shops everywhere.
