DSCR Loan Calculator: How Much Rental Income Do You Need to Qualify?
A DSCR lender does not look at your paycheck — it looks at whether the rent covers the payment. Here is the exact math behind every DSCR calculator, the rent lenders need at each ratio tier, and how to run it on a deal before you make an offer.

Quick rule of thumb
1.25 × PITIA
At the standard 1.25 target, rent must run 25% above the full payment — taxes, insurance and HOA included.
How much rental income do you need to qualify for a DSCR loan?
Your monthly gross rent must equal your full mortgage payment (PITIA) multiplied by the lender’s DSCR target. At the most common target of 1.25, rent needs to be 125% of principal, interest, taxes, insurance and HOA dues. A $2,800 PITIA needs $3,500 in rent; a $3,200 PITIA needs $4,000.
That single relationship is what every DSCR calculator is built on. Once you know it, you can price a property in your head before you ever call a lender — and you can tell in thirty seconds whether a listing can carry itself.
1.25
Standard tier
25% cushion over PITIA. The most common target for best pricing.
1.00
Break-even tier
Rent equals PITIA. Usually a price adjustment or larger down payment.
< 1.00
No-ratio tier
Rent below PITIA. Qualified on reserves, credit and equity instead.
Why DSCR flips the script: a conventional investment loan qualifies on your income, debt-to-income ratio and tax returns. A DSCR loan qualifies on the property. Investors with heavy write-offs, retired borrowers and self-employed owners can qualify on cash flow alone — which makes the calculator the most important tool you have.

APPLY NOWThe DSCR calculator, step by step
Lenders divide gross rent by PITIA to get the DSCR. To find the rent you need, you reverse it — and that is the only number that matters before you put in an offer.
Required rent
PITIA × DSCR Target
Lender side: DSCR = Gross Rent ÷ PITIA
Pick the DSCR target
Ask the lender which program tier fits your profile. Most investors target 1.25 for best pricing; 1.00–1.20 widens lender choice; below 1.00 needs a no-ratio program.
Build the full PITIA
Principal + interest + property taxes + hazard/flood insurance + HOA dues + mortgage insurance if any. This is the payment the ratio is measured against.
Multiply
PITIA × DSCR target = required gross rent. At 1.25, rent must be 25% above PITIA. At 1.00, it must just cover it.
Compare to verified rent
The lender uses the lower of the lease and the appraiser's market-rent opinion. If verified rent clears your required rent, you qualify.
What counts in PITIA — and what most calculators get wrong
PITIA is the number the DSCR is measured against. Use principal and interest only, and your required rent can look hundreds of dollars lower than it really is — which is how deals fall apart at underwriting.
Principal
The part of each payment that reduces the loan balance.
Interest
Driven by rate and loan size. A 0.25% rate change moves required rent noticeably.
Taxes
The lender collects 1/12 of the annual property tax bill each month.
Insurance
Hazard and, where required, flood insurance — a landlord policy, not homeowners.
Association dues
Monthly HOA dues are included. If they're not escrowed, expect the lender to account for them anyway.

Illustration only. HOA dues, mortgage insurance, flood insurance and your actual rate and tax bill will change the PITIA — and therefore the rent needed.
Lower rent? More down payment closes the gap
A DSCR loan does not require a fixed down payment like FHA — it asks whether the rent covers the payment. When the rent on a property is short of your target, a larger down payment lowers the loan, lowers PITIA, and lowers the rent you need to show.
1.25+
Standard
20–25% down
Best pricing and the widest lender choice. Most investors aim here because the rent cushion protects against vacancy and repairs.
1.00 – 1.24
Acceptable
25% down typical
Common and well supported. Expect a modest rate adjustment, and confirm your lender's minimum — some set 1.10 or 1.20.
Below 1.00
No-ratio
30%+ down
Qualified on reserves, credit and equity instead of cash flow. Stronger borrowers with larger down payments only.
Worked example: $450,000 purchase, 7.25%, 1.2% taxes, $160 insurance, $75 HOA
The rent needed at a 1.25 DSCR, by down payment.
| Down payment | Loan | P&I | PITIA | Rent @ 1.25 |
|---|---|---|---|---|
| 75% LTV (25% down) | $337,500 | $2,331 | $3,016 | $3,770 |
| 70% LTV (30% down) | $315,000 | $2,149 | $2,834 | $3,543 |
| 65% LTV (35% down) | $292,500 | $1,996 | $2,681 | $3,351 |
Going from 25% to 35% down cuts required rent by roughly $419 a month — often the difference between a deal that qualifies and one that does not.
APPLY NOWWhat rent the lender actually counts
Your rent estimate and the rent on your calculator are not the same thing as the rent a lender will credit. The lender’s number is almost always the lower of the lease and the appraiser’s market-rent opinion. Plan around that, not your optimistic projection.
Signed lease
A fully executed lease is the strongest proof. Lenders generally use the monthly rent stated on it — provided it is at or near market.
Appraiser's market rent (1007)
When a unit is vacant, lenders rely on the appraiser's market-rent opinion. It must support the lease or your projected rent.
Short-term rental history
Airbnb and VRBO deals usually need 12 months of platform statements, and lenders often apply a vacancy factor.
Five calculator mistakes that kill deals
Every one of these is a number that looked fine on a spreadsheet and turned into a problem at underwriting — usually after a non-refundable deposit or an appraisal fee.
APPLY NOWUsing principal & interest instead of PITIA
The single most common error. Add taxes, insurance and HOA or you will understate the rent you need by hundreds of dollars a month.
Guessing rent optimistically
The lender uses the lower of the lease and the appraiser's market rent. A deal that pencils at your optimistic rent fails at appraisal.
Ignoring the rate you were actually quoted
Run the calculator at the rate on your scenario, not a headline rate. Each 0.25% moves PITIA and required rent on a $400k loan by roughly $60.
Forgetting HOA dues, mortgage insurance or flood insurance
Condos and flood zones add real monthly cost. Those items live inside PITIA and are counted against your rent.
Not stress-testing a lower DSCR
If a lender quotes 1.20 instead of 1.25, the rent you need goes up. Run the number at your lender's minimum, not your target.
