💰 Money Weight Calculator

How to Use This Calculator

Enter how many bills and coins you have in each field, then hit Weigh My Cash. Every US bill weighs 1 gram regardless of denomination, so the three bill fields just need counts; coins use their standard weights. The headline shows total weight in the most readable unit (grams, ounces, pounds, or kilograms depending on size), with the full breakdown and the cash value in the details. Worn bills weigh slightly less than a gram, so treat totals as approximate for circulated cash.

The Method: Grams Per Unit

The bill weight is the elegant part: one gram each, all denominations, because the paper and size are uniform. Coins carry their mint-specified weights, with dimes the lightest per unit of value and pennies the heaviest. The worked example shows why denomination matters for transport: $10,000 in hundreds is 100 grams you can pocket, while the same value in ones is 10,000 grams requiring luggage. Unit conversion at the end picks the human-readable scale: grams under 100, ounces under a pound, pounds under 50, kilograms above. Circulated bills lose a few percent to wear, so bank-fresh straps match the math best.

Worked Example

A cash register holds 40 twenties, 60 small bills, 80 quarters, 100 dimes, and 200 pennies. Bills: 100 x 1 g = 100 g. Quarters: 80 x 5.67 = 453.6 g. Dimes: 100 x 2.268 = 226.8 g. Pennies: 200 x 2.5 = 500 g. Total = 1,280.4 g = 45.2 oz = 2.82 lbs. Cash value: 800 + 60 + 20 + 10 + 2 = $892. Notice coins dominate the weight: $32 in coins weighs over a kilogram while $860 in bills weighs 100 grams. Enter those counts above and the calculator reproduces the 2.82 pounds.

Famous Money Weights

A million dollars in hundreds: 10 kg (22 lbs), a carry-on. In twenties: 50 kg (110 lbs), a checked bag at the limit. In ones: 1,000 kg, a small car's worth. A bank strap of 100 bills: 100 grams. A standard bank bag of $1,000 in ones: 1 kg. These figures explain heist-movie logistics: the difficulty is never the value, it is the mass. They also explain why high-value transfers go electronic: moving a ton of paper to move a million dollars is a logistics operation, not a transaction.

Weighing to Count

Banks and vending operators invert this math: weigh a stack of single-denomination bills and divide by 1 gram for the count. Coin counters use weight per denomination the same way. For personal use, a kitchen scale and this calculator verify cash counts fast: weigh 100 supposed ones and expect 100 grams. Counterfeit detection by weight is unreliable (good fakes match weight), but count verification by weight is solid. Just keep denominations separate; mixed stacks defeat the method completely.

Bank Deposits: Rules for Cash Weight

Banks accept cash by count, not weight, but weight tells you what to expect at the counter. Large cash deposits trigger paperwork: US banks file a Currency Transaction Report at $10,000, which is routine and not an accusation, but structuring deposits to dodge it is a federal crime. Business depositors with heavy cash should ask about their bank's cash handling: some branches limit loose coin, require rolled coin, or direct you to commercial deposit bags. Coin counting machines (in-branch, usually free for account holders) beat rolling by hand; the supermarket machines take around 10 percent. For the weight math in this calculator, remember it is an estimate for planning (luggage, safes, shipping), not a banking instrument. When moving serious cash, use the bank's own logistics: that is what the fees are for.

Coinstar Fees and Alternatives

Those supermarket coin machines charge about 10-12 percent for cash, which is steep on a big jar. The fee-free workaround: take the e-gift card option, which most machines offer without charge for major retailers. If you actually want cash, your bank's coin counter is usually free for account holders, and some credit unions still do it. Rolling coins by hand costs only time and gets full value; a $10 box of penny wrappers turns a jar into bank-ready rolls in an evening. For kids' savings, the rolling ritual teaches denominations better than any app. Whatever you do, do not pay to convert coins you could spend: many self-checkouts and laundromats take coins at face value, no fee at all.

The Heist Math: What Movie Money Would Weigh

Every heist movie ignores the weight, so let us do it properly. One million dollars in $100 bills is 10,000 bills at 1 gram each: 10 kilograms, about 22 pounds, a comfortable duffel bag. The same million in $20 bills is 50,000 bills: 50 kilograms, 110 pounds, a load that needs two people and a dolly. In $1 bills it is a metric ton, literally 1,000 kilograms, which is why no movie crew ever carries the million in ones.

Coins are worse. A million dollars in quarters is 4 million coins at 5.67 grams: 22,680 kilograms, about 25 tons, roughly a loaded dump truck. This is why bank robbers in the real world never take coin: the value density is absurd. A standard bank bag holds about $200,000 in hundreds at 2 kilograms. The movies show a hero sprinting with a bag of cash, and for once the movies are right, as long as the bag holds hundreds and the hero skips leg day never.

The Bank Bag Standard

Banks standardize cash by the strap: 100 bills banded together, so a strap of $100s is $10,000 and weighs 100 grams, a strap of $20s is $2,000 at the same 100 grams. Ten straps make a bundle: $100,000 in hundreds is a 1-kilogram brick the size of a paperback book. Coin rolls are standardized too: 40 quarters to $10 at 226.8 grams, 50 dimes to $5 at 113.4 grams, 40 nickels to $2 at 200 grams, 50 pennies to 50 cents at 125 grams. A full box of quarter rolls, $500, weighs over 11 pounds, which is why tellers handle coin with carts, not hands.

For travelers, the weight math runs in reverse: $10,000 in hundreds is the US customs reporting threshold and weighs exactly 100 grams, pocket change in a jacket. The form, not the weight, is the thing to worry about at the border.
