Christmas Holiday Card Postage Calculator: $55.50 Total
On the defaults — 50 domestic cards at $0.78 a card plus 10 international cards at $1.65 a card — holiday card postage costs $55.50 in all, $39.00 domestic, $16.50 international. This is the holiday card postage tool: domestic cards times the domestic rate is the domestic cost, international cards times the international rate is the international cost, and the two together are the total — a card list tells you nothing until the two piles and the two rates are counted.
What does $55.50 mean?
It means 50 domestic holiday cards at $0.78 a card plus 10 international cards at $1.65 a card cost fifty-five dollars and fifty cents in all, which is $39.00 domestic, $16.50 international, 60 cards, and $0.93 a card on average. The domestic count sets how many cards stay in the country, the international count sets how many cross a border, and the two postage rates set how dear each pile is: ten more domestic cards add $7.80 at the default rate, and dearer international postage lifts the total without touching the domestic pile at all. The only judgement is the card counts themselves — a card list and a posted pile are not the same thing, and the cards actually posted are the only honest source for them.

Three things to check before you trust the number
First, check the domestic count honestly: 50 cards must be cards actually posted at home, not cards written that never left the house — a card counted that was never posted adds $0.78 that was never spent. Second, check the international count against the address list: 10 cards must be cards actually sent abroad, not cards meant for abroad that went to a home address instead — a mis-sorted card is charged at the wrong rate in both piles. Third, check the postage rates against the post office actually used: $0.78 and $1.65 must be the rates for those cards, not last year’s rates — a rate rise between writing and posting breaks the total by the rise on every card.
Worked example
50 domestic cards, $0.78 a card, 10 international cards, $1.65 a card. Domestic: 50 × $0.78 = $39.00. International: 10 × $1.65 = $16.50. Total: $39.00 + $16.50 = $55.50. Cards: 50 + 10 = 60. Average a card: $55.50 ÷ 60 = $0.93. In practice that means a holiday card list costs about fifty-five dollars to post, and the $39.00 domestic figure is the one to set against a home-only list, since the international pile is priced at more than twice the domestic rate.
Every branch, checked
At 40 domestic cards instead of 50, the total falls to $47.70 — $31.20 domestic, 50 cards, $0.95 a card on average. At 20 international cards instead of 10, the total rises to $72.00 — $33.00 international, 70 cards, $1.03 a card on average. At $0.73 domestic postage instead of $0.78, the total falls to $53.00 — $36.50 domestic, $0.88 a card on average. At $0 international postage instead of $1.65, the total falls to $39.00 — $0.00 international, $0.65 a card on average.
The reverses, worked backwards
The domestic cards behind $55.50 are 50: at 40 domestic cards the total is $47.70; at 60 domestic cards it is $63.30, 70 cards, $0.90 a card on average. The international postage behind $55.50 is $1.65 a card: at $1.20 a card the total is $51.00, $0.85 a card on average; at $2.10 a card it is $60.00, $1.00 a card on average — the international rate never touches the domestic pile, only how dear each card abroad is.
What the defaults assume
The defaults assume 50 domestic cards, $0.78 a card, 10 international cards, and $1.65 a card, for one holiday card list posted in one batch. They do not assume the cards themselves, envelopes, return address labels, or a second posting — so treat $55.50 as the planning cost for postage alone on 50 domestic and 10 international cards, and check it against the post office rates actually charged before budgeting it as exact.
Who uses this
- Someone posting Christmas cards: the $55.50 is the figure to set against the festive budget.
- A family with relatives abroad: the international figure shows what the overseas pile costs before stamps are bought.
- A charity sending appeal cards: the average figure prices each card fairly when the list mixes home and abroad.
- A small business sending holiday cards: the domestic figure shows what the home list costs before the overseas list is added.
Accuracy & limitations
The arithmetic is exact for the inputs entered; the judgement is the cards actually posted in each pile, and whether the postage rates are the rates actually charged for those cards. Real posting varies with card size, weight and rate rises — so treat $55.50 as the planning cost for 50 domestic cards at $0.78 plus 10 international cards at $1.65, and check it against the post office before budgeting it as exact.
