Covers itself, below the usual minimum

1.18 clears 1.00 but sits under the 1.20 most programs treat as their floor. Expect a lower loan-to-value, a rate add-on, or both. Rent of $2,607 would reach your 1.25 target. This basis charges no vacancy, management or maintenance. With those in, the property runs $153 a month short and the other convention reads 0.90.

How this is calculated

Debt service coverage ratio is one division: the income a property produces over the debt it has to pay. Above 1.00 the property covers itself; below it, something else has to make up the difference every month.

The catch is that both halves of that fraction have two definitions in common use, and this calculator offers both rather than picking one. The commercial convention is DSCR = net operating income ÷ annual principal and interest, where net operating income is rent after vacancy, management, maintenance, taxes, insurance, HOA and everything else the property costs to run, but before the loan. The residential DSCR-lender convention is DSCR = gross scheduled rent ÷ annual PITIA, where PITIA is principal, interest, taxes, insurance and HOA, and where vacancy, management and repairs are not charged at all.

On the same house those two answers can differ by twenty points or more, and the commercial one is nearly always the lower. Neither is wrong. They are answering slightly different questions — one asks whether the asset services its debt out of what it really earns, the other asks whether the contracted rent covers the contracted obligations. Match the toggle to what your lender uses before you compare notes with them.

The break-even rent runs the same arithmetic backwards. On the net operating income basis, the percentage expenses scale with rent, so it solves required income = (target × debt service + fixed expenses) ÷ (1 − management% − maintenance%) and then divides back out through vacancy to a monthly figure. On the gross-rent basis the escrow items do not move with rent, so it is simply target × PITIA ÷ 12. That is the rent at which the ratio you asked for arrives, and the gap to your current rent is the size of the problem.

The rate sensitivity table re-prices the loan at three-quarter-point steps either side of your rate and recomputes the ratio at each. Nothing else on the page moves a DSCR as fast as the rate does, because the entire payment is in the denominator.

Common questions

  • What DSCR do lenders actually want?

    Most residential DSCR programs treat 1.20 as the comfortable minimum and 1.25 as the level where pricing stops being penalised. A ratio between 1.00 and 1.19 is often still lendable, at a lower loan-to-value or a higher rate. Some lenders will write below 1.00 — a so-called no-ratio or low-ratio loan — but you should expect a materially larger down payment. Commercial lenders on multifamily typically start at 1.25 and go higher for older assets or shorter leases. None of these are rules; they are where the market has settled, and any individual lender's overlays beat all of them.

  • Why does my lender's DSCR differ from the one I calculate?

    Because there is no single agreed formula. Residential DSCR lenders usually divide gross scheduled rent by PITIA — principal, interest, taxes, insurance and HOA — and ignore vacancy, management and maintenance entirely. Commercial underwriters divide net operating income by principal and interest only, after charging vacancy, management and a repairs reserve. On the same property those two produce visibly different numbers, and the second is almost always lower. Ask which the lender uses before you argue about the answer, and use the toggle here to match it.

  • Does the calculator use market rent or my actual lease?

    Whichever you type. Lenders differ here too. A DSCR lender ordering an appraisal with a rent schedule attached will commonly take the lesser of the appraiser's market rent and the rent on your signed lease, which means a lease you wrote below market caps the ratio you can claim. If the unit is vacant, they use the appraiser's market rent, sometimes with a haircut. Run it both ways: the gap between your lease rent and market rent is the exposure you carry into underwriting.

  • Is a high DSCR always better?

    For qualifying, yes. For returns, not necessarily. A very high ratio usually means you have put a lot of cash down, and a property covering its debt three times over with half the price in equity may be earning a poor return on that equity. DSCR is a lender's safety measure, not an investor's performance measure — it answers whether the income survives a bad year, not whether your money is well placed. Read it beside cash-on-cash return, not instead of it.

  • What happens to my DSCR if rates move?

    More than most people expect, because the whole payment sits in the denominator. On a thirty-year amortising loan, a one-point move in the rate changes the payment by roughly ten to twelve percent, and the ratio moves by about the same amount in the opposite direction. That is why a deal underwritten at 1.25 during a rate lock can arrive at closing near 1.12 if the lock expires. The rate sensitivity table on this page shows the size of that move on your specific loan.

  • Do I include vacancy and maintenance?

    If you are underwriting for yourself, yes — a property that only covers its debt when it is occupied every day of the year and never needs a repair does not cover its debt. If you are matching a residential DSCR lender's figure, usually no: that convention charges only taxes, insurance and HOA. Both are on this page. The honest position is to qualify with the lender's number and decide with yours, and to be unsurprised when yours is lower.
