Total bills and coins quickly.
About the Money Counter
Count a till or a jar by denomination rather than adding coins one at a time.
How to use it
- Enter how many of each note and coin.
- The total updates as you type.
The formula
Counting a till is one multiplication per denomination and one sum. The value is in doing it the same way every time.
Total = Σ (Count of each denomination × Its value)
Work from the largest denomination down, and record counts rather than running totals. If the drawer disagrees with the register, a written list of counts tells you which denomination is wrong, while a single total tells you only that something is.
Standard bundling helps enormously, because a full strap or roll is a known quantity you never have to recount. US coin rolls hold fixed amounts: pennies $0.50, nickels $2, dimes $5 and quarters $10. Note that pennies and dimes come 50 to a roll while nickels and quarters come 40 — every roll is a round dollar figure, but the counts differ.
Worked examples
| Denomination | Count | Value | Full roll or strap |
|---|---|---|---|
| $20 notes | 12 | $240 | strap of 50 = $1,000 |
| $5 notes | 8 | $40 | strap of 100 = $500 |
| Quarters | 40 | $10 | roll of 40 = $10 |
| Dimes | 50 | $5 | roll of 50 = $5 |
The two coin rows show the quirk that causes most miscounts. A roll of quarters and a roll of dimes are both round dollar amounts, and they contain different numbers of coins — 40 against 50. Anyone counting by rolls is safe; anyone assuming a roll is always fifty coins will be $2.50 out on every roll of quarters they touch.
Common mistakes
- Counting up a running total in your head. Record the count for each denomination, then multiply. A running mental total cannot be checked, and a discrepancy gives you no clue where to look.
- Assuming every coin roll holds the same number. Pennies and dimes come 50 to a roll; nickels and quarters come 40. The dollar values are round, the counts are not consistent.
- Counting in a busy or interrupted space. Interruptions are how counts go wrong. Count where you will not be disturbed, and start the denomination again rather than guessing where you were.
- Not counting twice when it matters. For a deposit or a shift handover, count independently a second time and compare. A recount that merely follows the first count's rhythm repeats its errors.
Terms explained
- Denomination
- The face value of a note or coin.
- Strap
- A bundle of 100 notes of one denomination, banded together. $20 straps are commonly made up as 50 notes for $1,000.
- Roll
- A tube of coins in a fixed count: 50 pennies, 40 nickels, 50 dimes, 40 quarters.
- Float
- The starting cash left in a till to make change at the beginning of a shift.
- Over and short
- The difference between counted cash and what the register expected. Over means too much, short means too little.
- Skim
- Removing excess large notes from a till during a shift, reducing what is at risk in the drawer.
Common questions
- How much is a roll of quarters?
- $10 — 40 quarters. Dimes are $5 for 50, nickels $2 for 40, and pennies $0.50 for 50.
- What is the fastest way to count a till?
- Sort by denomination first, count each stack separately, write the counts down, then multiply and sum. Sorting before counting is faster overall than counting as you sort.
- Why write down counts instead of a total?
- Because if the drawer is short, the counts show which denomination to recount. A single total tells you there is a problem and nothing about where it is.
- How many notes are in a bank strap?
- 100 notes of a single denomination is the standard strap, so $500 in fives or $2,000 in twenties. Some businesses strap twenties in fifties to make a round $1,000.
- What should I do if the till is short?
- Recount from scratch rather than adjusting, check for notes stuck together, and confirm the float was correct at the start. Report it under your workplace's procedure — a recorded small discrepancy is routine, an unrecorded one is not.
- Should two people count a deposit?
- For anything substantial, yes. Two independent counts that agree are far stronger evidence than one count done twice by the same person.
- How do I count large amounts of change quickly?
- By weight or by rolling. Coin values are standardised by weight closely enough that scales are used commercially, and rolling turns a heap into a small number of known quantities.
- What is a float and how big should it be?
- The starting cash for making change, commonly $100 to $200 weighted toward small denominations. Enough to cover a busy opening hour without leaving unnecessary cash in the drawer.
