Money Counter
Total up a cash drawer, tip jar, or piggy bank fast. Enter the count of each U.S. denomination — $100, $50, $20, $10, $5, and $1 bills, plus quarters, dimes, nickels, and pennies — and get the grand total with bill and coin subtotals.
Example: with $100 bills 2 · $50 bills 1 · $20 bills 8 · $10 bills 5 · $5 bills 6 → Total cash: $523.15.

Total = Σ(count × face value). The math runs in whole cents, so penny-level results are exact — no floating-point drift.
Counting cash without errors
Every cash count is the same arithmetic: multiply the number of pieces of each denomination by its face value, then add. Two $100s, one $50, eight $20s, five $10s, six $5s, and twenty-two $1s is $512 in bills; add 30 quarters ($7.50), 25 dimes ($2.50), 15 nickels ($0.75), and 40 pennies ($0.40) for $523.15 total. The reliable method is to count pieces first and let the multiplication happen once — recounting values mid-stack is where errors creep in.
This tool computes in whole cents rather than decimal dollars, which sidesteps the classic floating-point trap (0.1 + 0.2 ≠ 0.3 in binary math). For drawer counts, sort by denomination, count each pile twice, and enter the counts — the subtotals make it easy to spot which pile to recount if the drawer is off.
How it’s calculated
Total = 100×(hundreds) + 50×(fifties) + 20×(twenties) + 10×(tens) + 5×(fives) + 1×(ones) + 0.25×(quarters) + 0.10×(dimes) + 0.05×(nickels) + 0.01×(pennies). All arithmetic is done in integer cents and formatted back to dollars, so results are exact to the penny.
Counts are rounded to whole pieces; $2 bills, half-dollars, and dollar coins are not broken out — add them to your total by hand if you have any.
Standard U.S. coin rolls
| Coin | Coins per roll | Roll value |
|---|---|---|
| Pennies | 50 | $0.50 |
| Nickels | 40 | $2.00 |
| Dimes | 50 | $5.00 |
| Quarters | 40 | $10.00 |

Common mistakes
- Counting a strap or roll as one piece — enter the number of individual bills or coins, or convert rolls first (a quarter roll is 40 coins, $10).
- Typing dollar values instead of counts: the fields want how many pieces you have, not what they are worth.
- Mixing $10s into the $20 pile before counting — sort completely by denomination first, then count.
- Adding decimal dollars by hand for coins ($7.50 + $2.50 + ...) and losing pennies to rounding or slips; count pieces and multiply once.
Frequently asked questions
How does the money counter compute the total?
Total = Σ(count × denomination): 100×hundreds + 50×fifties + 20×twenties + 10×tens + 5×fives + 1×ones + 0.25×quarters + 0.10×dimes + 0.05×nickels + 0.01×pennies.
How much is a roll of quarters worth?
A standard roll holds 40 quarters, so it is worth $10. Pennies roll 50 to a wrapper ($0.50), nickels 40 ($2.00), and dimes 50 ($5.00).
Do I enter the value of my bills or the number of them?
The number. If you have eight $20 bills, enter 8 in the $20 field — the calculator multiplies by the face value for you. Entering 160 would count 160 separate twenties.
What about $2 bills or dollar coins?
They are uncommon enough that there is no field for them. Count them separately — each $2 bill adds $2.00, each dollar coin $1.00, each half-dollar $0.50 — and add that to the total.
