How the DealQuanta Score Is Calculated
A transparent 0–100 grade built from the six metrics investors actually screen on — no black box.
What the Score is
Every deal you run through DealQuanta gets a single 0–100 quality score and an A–F letter grade. It exists so you can screen a whole pipeline at a glance instead of squinting at a dozen metrics. The score is fully transparent: it's a weighted blend of six numbers, and nothing is hidden. The same score appears in the app, on shared deal links, and in your PDF reports — there is one source of truth and it is never recomputed differently anywhere.
The six factors and their weights
Each factor earns points on a linear ramp between a floor (where it earns nothing) and a ceiling (where it earns the full weight). Values in between earn a proportional share; values above the ceiling are capped at the maximum. The weights sum to exactly 100.
| Factor | Max points | How points are earned |
|---|---|---|
| Cash-on-cash return | 25 | 0% earns nothing; 12%+ earns the full 25 points |
| DSCR | 20 | 1.00 earns nothing; 1.50+ earns the full 20 points |
| Cap rate | 15 | 4% earns nothing; 8%+ earns the full 15 points |
| Monthly cash flow | 15 | $0 earns nothing; $300+/mo earns the full 15 points |
| 5-year IRR | 15 | 0% earns nothing; 15%+ earns the full 15 points |
| Rent-to-price (1% rule) | 10 | 0.50% earns nothing; 1.00%+ earns the full 10 points |
| Total | 100 |
Cash-on-cash and DSCR carry the most weight on purpose: they answer "what does this return on my money" and "can it comfortably cover its debt." Cap rate, monthly cash flow and the 5-year IRR round out the return picture, and the 1% rule contributes a small sanity check on rent relative to price.
The A–F grade bands
The total points map to a letter grade on these fixed bands:
| Grade | Score | What it means |
|---|---|---|
| A | 85–100 | Excellent — strong cash flow and returns with a healthy safety margin. |
| B | 70–84 | Good — solid fundamentals; a few levers could push it higher. |
| C | 55–69 | Fair — workable but sensitive to rent, rate, or expense assumptions. |
| D | 40–54 | Weak — thin margins and below-market returns on these assumptions. |
| F | 0–39 | Poor — well below investment-grade returns on these assumptions. |
The conventions behind the numbers
The score is only as good as the metrics underneath it, and those follow the residential investor standard:
• Percentage expenses and vacancy (management, maintenance, capex and the vacancy allowance) are taken as a percentage of gross scheduled rent.
• Operating expenses never include mortgage debt service(principal & interest) — NOI is calculated before financing.
• Cap rate uses the purchase price as its denominator, the market standard.
• DSCR is NOI ÷ annual debt service, and the 5-year IRR is computed over the full hold including sale proceeds.
The Score is a screening tool, not investment advice — it reflects the assumptions you enter. Run your own numbers in the free rental calculator and watch the grade update as you flex rent, rate and expenses.
