DSCR Loan Calculator:How Much Rental Income Do You Need to Qualify?
With a DSCR loan you do not need tax returns or W-2s — you need rent that covers the mortgage. This guide works the DSCR calculator backward, so you can see the exact monthly rent a lender needs before you make an offer.

The core formula
DSCR = Gross Rent ÷ PITIA
Need 1.25? Rent must equal 125% of the full payment.
How much rental income do you need for a DSCR loan?
You need monthly rent equal to your full mortgage payment (PITIA) multiplied by the lender's DSCR target. At the most common target of 1.25, that means rent must be 125% of the principal, interest, taxes, insurance and HOA payment. On a $3,200 PITIA, the required rent is $4,000 a month.
Every DSCR loan calculator is built on one equation:
The DSCR formula
Required Rent = PITIA × DSCR Target
Rearrange it and you get the ratio a lender checks: DSCR = Rent ÷ PITIA
1.25
Standard tier
25% rent cushion over PITIA — the most common qualifying target
1.00
Break-even tier
Rent equals PITIA — usually a larger down payment or rate premium
<1.00
No-ratio tier
Rent falls short of PITIA — qualified on reserves, credit and equity
Why this matters before you shop: the number a lender uses is not your guess at rent — it is the lower of the signed lease and the appraiser's market rent opinion. Run the calculator with a conservative rent estimate and you will avoid the most expensive surprise in DSCR lending: a deal that looked fine on paper and fails at appraisal.
Why DSCR loans are different
A conventional investment-property loan qualifies on your income, debt-to-income ratio and tax returns. A DSCR loan qualifies on the property. The lender asks one question: does the rent cover the payment with enough left over? That means self-employed borrowers, retirees and investors with heavy write-offs can qualify on cash flow alone — and it means the calculator is the single most important tool you have.

Apply NowThe DSCR formula, step by step
Four steps — in this order. Getting any one of them wrong is how investors end up with a rent target that is thousands of dollars a year too optimistic.
Set your DSCR target
Ask the lender what program tier fits your profile. Most investors target 1.25 for the best pricing; 1.00 to 1.20 widens lender choice; below 1.00 needs a no-ratio program.
Calculate the full PITIA
Principal + Interest + Taxes + Insurance + HOA dues + any flood or mortgage insurance. This is the monthly payment the ratio is measured against — not just principal and interest.
Multiply to get required rent
PITIA × DSCR target = the gross monthly rent you need. At 1.25, rent must be 25% above the payment. At 1.00, rent must exactly equal it.
Compare to verified rent
The lender uses the lower of the executed lease and the appraiser's 1007 market rent opinion. If verified rent clears your required rent, you likely qualify.

Required rent at each target
Same property, same payment — only the lender's ratio target changes the rent you need. A stronger DSCR compresses underwriting friction, not the property's actual rent.
What counts in PITIA
PITIA is the full monthly housing payment. The most common calculator error is stopping at principal and interest — the denominator of your DSCR is bigger than that, which means the rent you need is bigger too.
Add every row below. If you forget taxes, insurance or HOA dues, your ratio looks better than the lender's — and the deal fails underwriting.
Principal
The portion of each payment that reduces the loan balance. On an interest-only loan this is $0 during the IO period — which lowers PITIA and the rent you need to qualify.
Interest
Set by the note rate on your DSCR loan. Rates are typically higher than conventional loans because DSCR programs are non-QM; a 1% rate difference on a $300,000 loan moves P&I by roughly $200 a month.
Taxes
The annual property tax bill divided by 12. Underwriters use the county's current assessed figure, not a buyer's estimate — verify the actual tax bill before you finalize the calc.
Insurance
Hazard and landlord liability coverage. Flood insurance is included if the property sits in a flood zone. Condo master policies may reduce hazard cost but do not eliminate the line.
Association dues
Monthly HOA, condo or PUD dues are always included. For condos the lender also checks project eligibility — a non-warrantable condo may need a different program entirely.
Reserves are not in PITIA — but most DSCR programs require 3 to 6 months of PITIA in reserves after closing. Plan liquidity separately from the monthly number.

How much rent do you need? By purchase price
The table below assumes 20% down, a 7.25% rate, 1.2% property tax, a $150 insurance premium and $50 HOA dues — then shows the gross monthly rent each DSCR target requires. Use it for a quick sanity check, then plug your real numbers into the calculator above.
| Purchase price | Loan (80%) | Est. PITIA | Rent @ 1.00 | Rent @ 1.25 | Rent @ 1.50 |
|---|---|---|---|---|---|
| $250,000 | $200,000 | $1,814 | $1,814 | $2,268 | $2,721 |
| $350,000 | $280,000 | $2,444 | $2,444 | $3,055 | $3,666 |
| $400,000 | $320,000 | $2,783 | $2,783 | $3,479 | $4,175 |
| $500,000 | $400,000 | $3,429 | $3,429 | $4,286 | $5,143 |
| $650,000 | $520,000 | $4,500 | $4,500 | $5,625 | $6,750 |
| $800,000 | $640,000 | $5,538 | $5,538 | $6,923 | $8,307 |
Every $100,000 of loan at 7.25% adds roughly $682 to monthly P&I — about $853 in required rent at a 1.25 target.
Lowering your rate by 0.5% on a $400,000 loan cuts PITIA by about $134 a month — and lowers your 1.25 rent requirement by roughly $168 a month.

Guidelines shift by lender and by year, so treat these as the ranges most programs cluster around — not contractual minimums. Program guidelines change; always confirm current thresholds before making an offer.
1.25+
Premium tier
- Sharpest DSCR program pricing
- Down payments from 15–20%
- Fewest reserve and credit overlays
- Most lender options — easier to shop
1.00 – 1.24
Standard tier
- Available with most DSCR lenders
- Rate hits and fee adjustments are common
- May require 20–25% down
- Reserves often bumped to 6 months
0.75 – 0.99
Stretch tier
- Larger down payments, typically 25–35%
- Highest rates in the DSCR lineup
- Credit score and reserves carry more weight
- Some programs apply vacancy stress tests
Below 0.75
No-ratio tier
- Underwritten on equity, credit and reserves
- Often 30–40% down or more
- Short-term rental and value-add plays
- Priced as a niche product
Shopping trick: ask each lender for its minimum ratio and its rate-adjusted ratio. A lender quoting a 1.00 minimum may charge a rate premium below 1.25 — which means a deal that technically qualifies can still be priced like a stretch file. Compare the all-in cost, not just the acceptance.
What rent do lenders actually count?
You have calculated the rent you need. Now the harder question: how much rent will the underwriter verify? The number in your calculator is only as good as the evidence behind it.
The rule of thumb across DSCR programs: qualifying rent is the lower of the lease and the appraiser's market rent, minus any vacancy adjustment the program applies.
Underwriting rule
Qualifying Rent = Lower of (Lease, 1007 Market Rent) × (1 − Vacancy)
Executed lease
A signed current lease carries the most weight. Lenders may apply a vacancy factor — often 5% or more — to leased rent before it enters the ratio.
Appraiser's 1007 rent opinion
When the property is vacant or the lease looks below market, the appraiser's market rent opinion can be used. Lenders take the lower of the two figures.
Short-term rental income
Airbnb and VRBO income is allowed on many DSCR programs but usually requires 12 months of platform statements and may use a reduced qualifying percentage of gross receipts.
Multi-unit rent schedule
On 2–4 unit properties, rent comes from each unit's lease and the 1007 form. Owner-occupied units are excluded, and the lender typically applies the same vacancy factor.
When rent is short: the down payment math
If the calculator says you are short, there are only so many dials. Here is how each one moves the required rent — sized so you can see whether it is worth pulling before you renegotiate the deal.
Increase the down payment
A smaller loan means a smaller P&I payment — and required rent falls with it. Dropping the loan by $10,000 at 7.25% removes about $68 from PITIA and roughly $85 from the 1.25 rent requirement.
Negotiate the purchase price
Price cuts hit both P&I and property taxes. On the $2,547 PITIA example, knocking $15,000 off the price at 75% LTV lowers required 1.25 rent by about $115 a month.
Shop a friendlier ratio tier
A 1.00 program needs about 20% less rent than a 1.25 program. That gap is often easier to bridge than a bigger down payment — if your credit and reserves support the tier.
Improve the income side
A tenant-signed lease above the appraiser's opinion helps only up to the appraised figure. Value-add improvements, a unit re-lease, or short-term rental strategy can raise verified market rent.
If you are short
Lower LTV
Going from 75% to 70% LTV on the $400,000 example property removes about $136 of PITIA and about $171 from required 1.25 rent.
If you are short
Price cut
$15,000 off the price at 75% LTV trims about $92 of PITIA and about $115 from required 1.25 rent, while also lowering annual taxes.
If you are short
Ratio tier
Moving from 1.25 to 1.00 lowers required rent by 20% — on a $2,547 PITIA, that is about $509 a month of needed rent.

Apply NowUsing only principal and interest
The fix: Always add taxes, insurance and HOA dues. Missing them makes your ratio look far healthier than the lender's — and required rent proportionally smaller than it really is.
Estimating rent optimistically
The fix: Use market rent from comparable leases, not a hoped-for number. The lender uses the lower of lease and appraiser opinion, so an optimistic figure is simply not the one that matters.
Forgetting the vacancy factor
The fix: Most programs haircut rent for vacancy before testing the ratio. Apply the same factor your lender uses — typically 5% or more — or you will overstate qualifying rent.
Comparing rates without the ratio
The fix: A lender's headline rate may come with a much higher DSCR minimum. Compare all-in cost at your actual ratio, not the advertised low-rate file that needs a 1.5.
Ignoring reserves
The fix: Reserves are not part of DSCR, but they are part of qualification. Most programs want 3–6 months of PITIA — and stretch tiers often require more.
