DSCR Loan Calculator

Q: Can I use this if I do not know the property value yet?

Yes. Switch to Enter loan amount directly and type your loan size. Property Value becomes optional. If you leave it blank, the LTV field shows "N/A — add property value." Every other result, including DSCR, still works fine.

Dscr Loan Calculator

Updated Aug 27, 2026 By Jehan Wadia

Introduction

A DSCR loan lets you buy a rental home based on the rent it earns, not your job income. DSCR stands for Debt Service Coverage Ratio. It compares the rent you collect each month to the full loan payment, including taxes, insurance, and HOA fees. Most lenders want a DSCR of at least 1.00, and many ask for 1.25 or more.

This DSCR loan calculator does that math for you. Enter the property price and down payment (or just the loan amount), the interest rate, the loan term, your monthly expenses, and the expected rent. The tool shows your monthly payment, your DSCR, and whether you pass your lender's target. If you only need the ratio itself without the loan sizing, the simpler DSCR Calculator handles that.

You also get both loan types side by side: a fixed payment loan and an interest-only loan. Interest-only payments are smaller, so the DSCR is higher. Seeing both helps you pick the option that qualifies. To dig deeper into either structure, try the Amortization Calculator or the Interest Only Mortgage Calculator.

Along with your DSCR score, the calculator shows your net operating income (NOI), your monthly cash flow, the rent you would need to hit your target, and a step-by-step breakdown of every formula. Charts and a rent scenario table let you test what happens if rent drops or rises, so you know how much cushion you really have before you make an offer. Pair it with the Cap Rate Calculator and the Rental Property Calculator to judge the whole deal.

How to use our DSCR Loan Calculator

Enter your rental property price, loan terms, monthly expenses, and rent. The calculator shows your monthly payment, your DSCR for both fixed and interest-only loans, and tells you if you hit your lender's target.

Loan input method: Pick "Derive loan from price & down payment" if you know the price and how much cash you will put down. Pick "Enter loan amount directly" if you already know your loan size.

Property Value ($): Type the purchase price or appraised value of the property.

Down Payment (%): Type the percent of the price you will pay up front, like 25 for 25%. Most DSCR lenders want 20% or more. The Down Payment Calculator can help you plan the cash.

Loan Amount ($): This fills in for you in derive mode. In direct mode, type the loan amount you want.

LTV (%): This is filled in for you. It shows your loan as a percent of the property value. See the LTV Calculator for more on that ratio.

Annual Interest Rate / APR (%): Type your loan rate, like 7.25 for 7.25%. Not sure of the true cost? Check the APR Calculator.

Loan Term: Choose how many years you will pay the loan back, from 10 to 40 years.

Interest-Only Loan?: Choose "Yes" if your loan only charges interest each month. Both loan types still show, so this just marks which one is your main result. The Interest Only Calculator breaks down that payment style.

Enter expenses as: Choose Monthly or Annual. The tool changes your expense numbers for you when you switch.

Property Taxes: Type your tax cost for the period you picked. Use the Property Tax Calculator if you need an estimate.

Insurance: Type your landlord or hazard insurance cost. The Homeowners Insurance Calculator gives a ballpark figure.

HOA Fees: Type your HOA dues. Leave it blank or put 0 if there is no HOA.

Total Monthly Expenses (TIA): This adds your taxes, insurance, and HOA into one monthly number for you.

Monthly Gross Rental Income ($): Type the full rent you expect to collect each month, before any costs. The Rental Income Calculator helps if you are still projecting rent.

Minimum DSCR Target: Type the lowest DSCR your lender will accept, like 1.25. Leave it blank to use 1.00.

What Is a DSCR Loan?

A DSCR loan is a mortgage for rental property. DSCR stands for Debt Service Coverage Ratio. Instead of looking at your job income or tax returns, the lender looks at the rent the property brings in. If the rent covers the loan payment, you can qualify. That is why real estate investors use these loans. Owner-occupied buyers usually go a different route, such as a standard mortgage, an FHA loan, or a VA loan, where a DTI Calculator matters more than DSCR.

How DSCR Is Calculated

The math is simple. You divide the rent by the full monthly housing payment:

DSCR = Monthly Rent ÷ PITIA

PITIA means Principal, Interest, Taxes, Insurance, and Association (HOA) dues. Most DSCR lenders use the whole PITIA payment, not just the loan part. A few use only principal and interest, so ask your lender which one they use. The PITI Calculator shows how the escrow pieces stack onto principal and interest.

What the Number Means

Below 1.00 — Rent does not cover the payment. You pay the difference out of pocket each month.
1.00 to 1.24 — Rent just covers the payment. There is little room for repairs or empty months.
1.25 and up — Strong coverage. Most lenders like this range.

Example: rent is $2,800 and PITIA is $2,300. The DSCR is 2,800 ÷ 2,300 = 1.22. That is marginal. Many lenders want at least 1.25, though some allow 1.00 or even lower with a bigger down payment.

Fixed vs. Interest-Only Payments

A fixed loan pays down principal and interest each month, so the payment is higher. An interest-only loan pays just the interest for a set time, so the payment is lower and the DSCR looks better. The trade-off is that you do not build equity during the interest-only period, and the payment jumps later when principal kicks in. Some investor loans end with a lump sum instead, which the Balloon Payment Calculator illustrates.

Down Payment and LTV

LTV means loan-to-value. It is the loan amount divided by the property value. Most DSCR loans need 20% to 25% down, which is an LTV of 75% to 80%. A bigger down payment means a smaller loan, a smaller payment, and a higher DSCR. Budget for the upfront costs too with the Closing Cost Calculator.

Ways to Raise Your DSCR

Put more money down to shrink the loan.
Shop for a lower interest rate and compare offers with the Loan Comparison Calculator.
Choose a longer term, like 30 or 40 years, to lower the monthly payment — see the 30 Year Mortgage Calculator.
Ask about an interest-only option.
Raise the rent to market rate, or buy in an area with stronger rents. Check returns with the Rental Yield Calculator.
Shop your insurance and appeal a high property tax bill.

Things to Watch

DSCR loans usually carry a rate about 1% to 2% higher than a normal home loan. Many have prepayment penalties in the first few years. Taxes, insurance, and HOA dues can rise and push your DSCR down, so leave yourself a cushion. Also remember that DSCR does not count repairs, vacancy, or property management fees. Your real cash flow can be tighter than the ratio suggests. Model the full picture with the Investment Property Calculator, or the Airbnb Calculator if you plan to rent short term. If you already own the home, the Cash Out Refinance Calculator and Refinance Calculator show what a new DSCR loan could do to your payment, and the ROI Calculator checks the return on your cash.

Frequently asked questions

Does this calculator include repairs, vacancy, or property management fees?

No. DSCR uses gross rent and the PITIA payment only. Lenders leave out repairs, vacancy, and management fees on purpose.

Your real cash flow will be lower than the ratio suggests. A good rule is to set aside 5% to 10% of rent for vacancy and another 5% to 10% for repairs, then check if you still have money left after the payment.

Why do the fixed and interest-only results both show even after I pick one?

So you can compare them. The Interest-Only toggle only marks which one is your Primary DSCR at the top of the results.

Both cards stay on screen because many DSCR lenders offer both. If the fixed loan fails your target but the interest-only loan passes, you know what to ask your lender about.

What is the Monthly cash flow row telling me?

It is your rent minus the full PITIA payment. A positive number means rent covers the payment with money left over. A negative number means you pay the gap from your own pocket.

This is not the same as profit. It does not subtract repairs, vacancy, or management costs.

What does the Rent needed to meet target DSCR number mean?

It is the monthly rent that would put you exactly at your DSCR target. The formula is PITIA × target DSCR.

The Gap row below it tells you two things:

More needed — your rent is short by that amount.
Of cushion — your rent is above the line by that amount, so you have room if rent drops.

Why is the NOI in this tool different from a standard NOI?

This tool uses annual rent minus annual taxes, insurance, and HOA. That matches what DSCR lenders look at.

A full appraisal-style NOI also subtracts vacancy, repairs, and management. So the NOI here will be higher than a full investment analysis NOI. Use it to check the loan, not to judge the whole deal.

Can I use this if I do not know the property value yet?

Yes. Switch to Enter loan amount directly and type your loan size. Property Value becomes optional.

If you leave it blank, the LTV field shows "N/A — add property value." Every other result, including DSCR, still works fine.

What happens if I switch from Monthly to Annual expenses?

The tool converts your numbers for you. Monthly values get multiplied by 12, and annual values get divided by 12.

So $350 monthly taxes become $4,200 annual taxes automatically. You do not need to retype anything.

Why does my DSCR go down when I pick a shorter loan term?

A shorter term packs the same loan into fewer payments, so each monthly payment is bigger. A bigger payment means a smaller DSCR.

Try switching the term from 15 to 30 or 40 years in the calculator. The DSCR jumps right away. That is why most DSCR investors choose 30 or 40 years.

What is the rent scenario table for?

It stress-tests your deal. It shows your DSCR if rent falls 20% or 10%, stays the same, or rises 10% or 20%.

If the −10% row still meets your target, your deal has real cushion. If even the current rent row barely passes, one rent drop or one vacancy could put you underwater.

My DSCR is 1.24 and my target is 1.25. Is that a deal breaker?

Not always, but you are one dollar short in the lender's eyes. Lenders do not round up.

Small fixes usually close a tiny gap: raise the down payment by a few percent, ask for an interest-only option, shop insurance, or stretch the term. Try each one in the calculator and watch the number move.

Should I enter my rate or my APR?

Enter your note rate, the plain interest rate on the loan. That is what lenders use to figure your actual monthly payment.

APR includes fees, so it is higher and would overstate your payment and understate your DSCR. Use APR only when comparing the total cost of two loan offers.

Why does my LTV say 75% when I put 25% down?

They are two sides of the same coin. Down payment plus LTV always equals 100%.

Put 25% down and you borrow the other 75%, so LTV is 75%. Put 20% down and LTV is 80%. Most DSCR lenders cap LTV at 75% to 80%.

Do I include utilities in the expense fields?

No. This calculator only takes taxes, insurance, and HOA, because that is what PITIA covers.

If you pay utilities, lawn care, or trash service, track those separately in your cash flow budget. They lower your real profit but do not change the DSCR your lender calculates.

What if my property has no HOA?

Leave the HOA field blank or type 0. The calculator treats a blank as zero and nothing breaks.

Your Total Monthly Expenses will then be just taxes plus insurance.

Why is the interest-only payment so much lower?

Because you pay only interest, with no principal. The math is loan × monthly rate.

On a $262,500 loan at 7.25%, interest-only is about $1,586 a month while the 30-year fixed payment is about $1,790. That $200 gap can lift your DSCR enough to qualify, but you build no equity while it lasts.

Can I enter a 0% interest rate?

Yes. The calculator handles it. With 0%, the fixed payment is just the loan divided by the number of months, and the interest-only payment is $0.

This is mostly useful for testing seller financing or a family loan, not a real DSCR lender.

What is the black marker on the gauge showing?

It marks your DSCR on a scale from 0.00 to 2.00 or more. The colored zones behind it are red below 1.00, orange from 1.00 to 1.24, and green at 1.25 and up.

If the marker sits in green, most lenders will like your deal. Red means rent does not cover the payment.

Does the down payment field include closing costs?

No. Down payment is only the cash applied to the purchase price. Closing costs, points, and reserves are extra.

Plan on 2% to 5% of the price for closing costs on top of your down payment. Many DSCR lenders also want a few months of PITIA in reserves.

Why did the calculator put an error under Down Payment when I typed 100?

A 100% down payment leaves no loan to analyze, so there is no payment and no DSCR to compute.

Lower the down payment below 100% and the results come back. If you are buying all cash, DSCR does not apply at all.

Can I use this for a multi-unit or short-term rental?

Yes. Add up the rent from every unit and enter the total in Monthly Gross Rental Income.

For short-term rentals, be careful. Lenders often use a 12-month average from a rental history report, not your best month. Enter a conservative average, then use the −10% and −20% rows in the scenario table to check slow seasons.
