Laundromat ROI Calculator: Is This Deal Actually Worth It?
The exact formulas to evaluate any laundromat opportunity
"What's the ROI?" is the question that matters. But most buyers don't know how to calculate it properly — and sellers definitely aren't going to help you.
Here's how to run the numbers yourself, with real formulas and examples from actual listings.
The 5 Numbers You Need
Before you can calculate anything, get these from the seller:
- Asking Price — What they want for the business
- Annual Revenue — Gross sales (self-service + wash-and-fold + other)
- Annual Cash Flow — Also called SDE (Seller's Discretionary Earnings) or net income
- Monthly Rent — Or mortgage payment if real estate is included
- Equipment Age — To estimate replacement costs
If the seller won't provide #2 and #3, walk away. You can't evaluate what you can't measure.
Metric #1: Cash-on-Cash Return
What it tells you: How much cash you'll earn relative to what you invest.
Formula: ``` Cash-on-Cash Return = (Annual Cash Flow ÷ Total Cash Invested) × 100 ```
Example:
- Asking price: $400,000
- Down payment (25%): $100,000
- Closing costs + working capital: $25,000
- Total cash invested: $125,000
- Annual cash flow: $80,000
- Minus debt service: $24,000/year
- Net cash flow: $56,000
Cash-on-Cash Return: $56,000 ÷ $125,000 = 44.8%
What's good:
- 20%+ = Solid
- 30%+ = Very good
- 40%+ = Excellent (verify the numbers twice)
- Under 15% = Probably not worth the hassle
Metric #2: Cash Flow Multiple (Payback Period)
What it tells you: How many years until the business pays for itself.
Formula: ``` Cash Flow Multiple = Asking Price ÷ Annual Cash Flow ```
Example:
- Asking price: $500,000
- Annual cash flow: $100,000
Cash Flow Multiple: $500,000 ÷ $100,000 = 5.0x (5-year payback)
What's good:
- Under 3x = Excellent (rare)
- 3x–4x = Very good
- 4x–5x = Fair
- 5x–6x = Needs justification
- 6x+ = Overpriced (unless includes real estate)
From our data: Median across 223 listings is 4.9x
Metric #3: Revenue Multiple
What it tells you: How the price compares to total sales.
Formula: ``` Revenue Multiple = Asking Price ÷ Annual Revenue ```
Example:
- Asking price: $450,000
- Annual revenue: $250,000
Revenue Multiple: $450,000 ÷ $250,000 = 1.8x
What's good:
- Under 1.5x = Great value
- 1.5x–2.0x = Fair
- 2.0x–2.5x = Getting expensive
- 2.5x+ = Premium pricing (needs justification)
Why it matters: Cash flow can be manipulated (defer maintenance, cut staff). Revenue is harder to fake. This metric sanity-checks the cash flow claims.
Metric #4: Operating Margin
What it tells you: How efficiently the business converts revenue to profit.
Formula: ``` Operating Margin = (Annual Cash Flow ÷ Annual Revenue) × 100 ```
Example:
- Annual revenue: $300,000
- Annual cash flow: $90,000
Operating Margin: $90,000 ÷ $300,000 = 30%
What's good:
- 35%+ = Excellent operations
- 25%–35% = Healthy
- 20%–25% = Investigate expenses
- Under 20% = Something's wrong (high rent, bad utilities, overstaffed)
Red flag: If margin is under 20%, ask why. High rent? California utilities? Constantly breaking equipment? Some issues are fixable. Others aren't.
Metric #5: Price Per Machine
What it tells you: Rough sanity check on valuation.
Formula: ``` Price Per Machine = Asking Price ÷ (Washers + Dryers) ```
Example:
- Asking price: $400,000
- Washers: 30
- Dryers: 30
Price Per Machine: $400,000 ÷ 60 = $6,667
What's good:
- $4,000–$7,000 = Normal range (business only)
- $7,000–$10,000 = Premium location or newer equipment
- $10,000+ = Includes real estate, or overpriced
- Under $4,000 = Old equipment, distressed sale, or hidden issues
Note: This metric is less reliable than cash flow multiples, but useful for quick filtering.

Real Deal Analysis: Three Examples
Example 1: The Solid Performer
Brooklyn, NY — $499,500
- Revenue: $330,000
- Cash Flow: $166,490
- Machines: 70
| Metric | Calculation | Result | Verdict |
|---|---|---|---|
| CF Multiple | $499K ÷ $166K | 3.0x | ✅ Excellent |
| Rev Multiple | $499K ÷ $330K | 1.5x | ✅ Good |
| Margin | $166K ÷ $330K | 50% | ✅ Excellent |
| Price/Machine | $499K ÷ 70 | $7,129 | ✅ Fair |
Investment Analysis (25% down):
- Cash invested: ~$150K
- Net annual cash: ~$130K (after debt)
- Cash-on-cash: ~87%
Verdict: This is a legitimately good deal. Verify the numbers hard.
Example 2: The Hidden Value
Riverside, CA — $125,000
- Revenue: Not disclosed
- Cash Flow: $96,000
- Listed as "zombie mat" needing work
| Metric | Calculation | Result | Verdict |
|---|---|---|---|
| CF Multiple | $125K ÷ $96K | 1.3x | ✅ Incredible |
| Rev Multiple | Unknown | — | ⚠️ Need data |
| Margin | Unknown | — | ⚠️ Need data |
Why so cheap? Seller wants out. Equipment likely needs attention. But even if you spend $50K on upgrades, you're at a 1.8x multiple with a renovated laundromat.
Verdict: High upside, but do your homework on why it's priced this way.
Example 3: The Overpriced Listing
[Redacted], IL — $625,000
- Revenue: $160,000
- Cash Flow: $45,000
- Machines: 60
| Metric | Calculation | Result | Verdict |
|---|---|---|---|
| CF Multiple | $625K ÷ $45K | 13.9x | ❌ Terrible |
| Rev Multiple | $625K ÷ $160K | 3.9x | ❌ Very high |
| Margin | $45K ÷ $160K | 28% | ⚠️ OK |
| Price/Machine | $625K ÷ 60 | $10,417 | ❌ Too high |
Verdict: Nearly 14 years to recoup your investment. Hard pass unless there's something major we're missing (like included real estate worth $400K+).
Adjustments to Consider
1. Equipment Replacement Reserve
If equipment is 10+ years old, budget for replacement:
- Washers: $3,000–$8,000 each (depending on size)
- Dryers: $2,000–$5,000 each
Adjustment: Add estimated replacement cost to your "total invested" calculation.
2. Below-Market Rent
If current rent is significantly below market, two things are true:
- Cash flow looks better than it is
- You might have leverage when the lease renews
Adjustment: Recalculate cash flow at market rent to see the "real" picture.
3. Owner Involvement
"Cash flow" often assumes owner doesn't work in the business. If you're planning to owner-operate:
- Your time has value
- But you might save on employee costs
Adjustment: Add back employee costs you'll eliminate; subtract a fair wage for your own time if comparing to other investments.
The Bottom Line
Before making an offer on any laundromat, run these numbers:
- Cash Flow Multiple — Is it under 5x?
- Revenue Multiple — Is it under 2x?
- Operating Margin — Is it over 25%?
- Cash-on-Cash Return — Is it over 20%?
If all four check out, you've found a deal worth pursuing. If multiple metrics fail, the price is wrong — either for the market or for you.
Don't let excitement override math. The numbers don't lie.
