How Much Change Do You Need for a Garage Sale?
Updated July 2026 · 5 min read
The short answer: start with $100 in change if you can, and never less than $40. Weight it heavily toward $1 bills and quarters - early birds love handing you a $20 for a 50¢ mug. Here's the exact breakdown that works for most sales, plus how to keep your starting cash from muddying your actual earnings.
The Recommended Change Breakdown
| Denomination | Amount | Why |
|---|---|---|
| Quarters (2 rolls) | $20 | Most items are priced in 25¢ increments |
| $1 bills (40) | $40 | The workhorse of every garage sale |
| $5 bills (6) | $30 | Breaking $10s and $20s |
| $10 bills (1) | $10 | Breaking the inevitable $50 or $100 |
| Total float | $100 |
On a budget? The $40 minimum version: $5 in quarters, fifteen $1 bills, and four $5 bills. You'll just need to recycle incoming small bills faster.
Pro move: price everything in 25¢ increments (or round numbers) so you never need dimes, nickels, or pennies. See our garage sale pricing guide for a full cheat sheet.
Cash Box Tips That Save Your Sanity
- Separate every denomination. A tackle box or cheap cash box with dividers beats a coffee can - you make change in seconds, not fumbles.
- Keep the box attended or wear the cash. A carpenter's apron or fanny pack means the money is on you, and you can make change anywhere in the yard.
- Skim big bills. Every hour or so, move $20s and larger inside the house. Never let the box hold more than you'd be okay losing.
- Accept digital payments as backup. A Venmo/Cash App/Zelle sign rescues sales when a buyer is short on cash. Record those in your tracker like any other sale so they're not forgotten.
The Float Problem: Don't Let Starting Cash Inflate Your "Earnings"
The classic end-of-day mistake: you count $412 in the box and celebrate - forgetting $100 of it was yours to begin with. The old fix is writing your float on an index card. The better fix is tracking sales, not cash:
- Record each sale as it happens in Rummage Register - one tap per transaction, with the app keeping a live running total of true sales.
- At close, compare: cash in box − starting float should equal the app's total (plus any digital payments). If it matches, perfect. If not, you know exactly how much walked away - and the timestamped sale list helps you figure out when.
- Multi-seller sale? The app also splits the total by seller automatically, so the single shared cash box stops being a bookkeeping problem. More on that in the multi-family garage sale guide.
Know your real total, all day long
Rummage Register keeps a live running total of actual sales - so the cash box math takes ten seconds, not an hour.

Should I get change from the bank or the grocery store?
The bank, a day or two before the sale. Ask for rolls of quarters and a strap of $1s - tellers do this constantly and it takes two minutes. Friday afternoon before a Saturday sale is the classic run.
What if someone pays with a $100 bill first thing?
It's okay to say "I can't break that yet - can you come back in an hour or pay another way?" Most buyers with big bills also have a payment app. Don't drain your entire float for one sale at 7am.
How much cash will I take in overall?
A typical single-family sale brings in $200-$600; multi-family sales can do much more. Track a couple of sales with the app and you'll have your own real numbers to plan next year's float.
