Cap Rate vs. Cash-on-Cash vs. DSCR: Which Metric Should Drive Your Next Buy?

Before choosing a lead metric, confirm you know what each one is actually answering:

• Cap Rate = (NOI ÷ Property Value) × 100 — Unlevered return on value. Ignores financing. Answers: “How much income does this asset produce per dollar of price?”
• Cash-on-Cash = (Annual Net Cash Flow ÷ Total Cash Invested) × 100 — Levered return on equity. Includes debt service. Answers: “What am I earning on the cash I actually put in?”
• DSCR = Annual NOI ÷ Annual Debt Service — Lender’s coverage test (a ratio, not a percentage). Answers: “Does operating income cover the mortgage with cushion?”

Same property, three different lenses. The rest of this article is about picking the right lens for the decision you are making today.

Lead with cap rate when financing is secondary — or when you want to strip leverage out of the comparison entirely.

• Comparing assets or markets — Cap rate normalizes income against price, so a duplex in one city can be weighed against a fourplex in another without guessing how each buyer financed the deal.
• All-cash acquisitions — When you are not borrowing, unlevered return on value is the most honest headline number. Cash-on-cash and cap rate converge when there is no debt, but cap rate is still the standard language brokers and appraisers use.
• Valuation and pricing decisions — If stabilized comps in a submarket trade at a 6% cap, you can sanity-check an asking price against NOI. A seller’s pro forma cash-on-cash is irrelevant if the price itself is out of line with market cap rates.
• Partner or JV screening — Equity partners often want to know asset quality before discussing leverage. Cap rate answers whether the underlying income justifies the price.

Rule of thumb: If the question is “Is this a fairly priced income-producing asset?” — cap rate leads.

Lead with cash-on-cash when you are deploying real dollars and care about what lands in your account after the lender gets paid.

• Leveraged buy-and-hold — Most residential investors put 20–25% down. Cash-on-cash reflects return on that equity, not the full purchase price. A 5% cap rate property can deliver 10%+ cash-on-cash with conservative financing.
• Comparing to other investments — When weighing a rental against dividends, bonds, or a high-yield savings account, you need the return on your capital at risk. Cap rate doesn’t capture that.
• Refinance or hold decisions — After a rate reset or cash-out refi, recalculate cash-on-cash on remaining equity. A property that still appraises well (strong cap rate) may no longer meet your personal return hurdle.
• Portfolio cash-flow planning — If your goal is monthly distributions to fund living expenses or fund the next acquisition, cash-on-cash is the metric that maps directly to bank-account reality.

Rule of thumb: If the question is “Is my money working hard enough for me?” — cash-on-cash leads.

Lead with DSCR when debt is part of the equation and someone — usually a lender — needs proof the property can carry its loan.

• Qualifying for DSCR or commercial loans — Many non-owner-occupied and portfolio lenders require minimum DSCR thresholds (commonly 1.20–1.25 on stabilized assets). Below the floor, the deal doesn’t close regardless of how attractive the cap rate looks.
• Stress-testing debt — Model DSCR at current rent, pro forma rent, and a vacancy haircut. If DSCR drops below 1.0 under realistic stress, you are one bad month from covering the mortgage out of pocket.
• Portfolio risk management — Track DSCR across holdings to spot assets vulnerable to rate adjustments or rising insurance and tax costs. A portfolio of strong cap-rate properties can still be fragile if several sit near 1.0 DSCR.
• Acquisition go/no-go with financing — Before waiving contingencies, confirm DSCR works at your actual loan terms, not the seller’s optimistic assumptions.

Rule of thumb: If the question is “Will this property survive its debt?” — DSCR leads.

The three metrics only disagree when leverage, pricing, or lender standards pull in different directions. Here is a worked scenario showing how conclusions diverge on the same deal:

The property: A small multifamily asset priced at $800,000. Stabilized NOI is $56,000/year. You plan 25% down ($200,000) plus $30,000 in closing and reserves ($230,000 total cash invested). Annual debt service on the $600,000 loan is $48,000. After debt service and all other expenses, annual net cash flow to you is $2,000.

• Cap rate = 7.0% — ($56,000 ÷ $800,000) × 100. Solid for the market. On an unlevered basis, this looks like a fairly priced income asset. A cap-rate-led buyer might move forward.
• Cash-on-cash = 0.9% — ($2,000 ÷ $230,000) × 100. Barely positive. A cash-on-cash-led buyer comparing this to a 5% bond or another rental delivering 8% would walk away — even though the asset itself earns a respectable unlevered return.
• DSCR = 1.17 — $56,000 ÷ $48,000. Below the 1.20–1.25 minimum many DSCR lenders require. A DSCR-led buyer (or their lender) may decline the loan or demand more equity, changing the entire capital stack.

Same property, three different verdicts. The cap-rate buyer sees value; the cash-on-cash buyer sees weak personal return; the DSCR buyer sees financing risk. None of them is “wrong” — they are answering different questions. Your job is to know which question matters most for this acquisition.

Practical sequencing: Screen with cap rate, confirm financing with DSCR, then decide whether the leveraged cash-on-cash justifies the operational effort. Skip a step and you can end up with a fairly priced asset you can’t finance — or one you finance but regret holding.

You don’t need three spreadsheets to run this analysis. On Manager > Metrics, pick the metric type from the dropdown at the top of the page and enter your inputs:

• Capitalization Rate — Enter NOI and current market value. Ideal for unlevered comparisons and pricing checks.
• Cash on Cash Return — Enter annual net cash flow and total cash invested. Document your down payment and closing breakdown in the memo field.
• Debt Service Coverage Ratio — Enter annual NOI and annual debt service. Use the same NOI definition as cap rate for consistency across records.

Each metric type has its own grid where you can add, edit, and export records. Attach memos to capture assumptions — vacancy rates, loan terms, expense estimates — so you can revisit the same deal months later without rebuilding the model from scratch.

The Metrics workspace is available on the Investor plan. Model cap rate, cash-on-cash, and DSCR side by side on every deal in your pipeline, then keep the snapshots as an underwriting library independent of any single reporting period.
