How the calculator works

DSCR stands for debt service coverage ratio. The calculator divides the monthly rent by the full monthly payment, which lenders call PITIA: principal, interest, property taxes, insurance and association dues. A result of 1.00 means the rent covers the payment exactly.

Here’s what to put in each box:

Monthly rent. Use the lease if the property is rented. If it’s vacant or you’re buying it, use a realistic market rent. Lenders usually lean on the appraiser’s rent estimate in that case.
Principal and interest. If you don’t have a payment yet, enter the loan amount, rate and term in the gray box and the calculator fills it in. Check the interest-only box if your quote has an interest-only period.
Property tax. Use the tax you’ll pay as the new owner. In Florida a sale resets the assessed value, so the seller’s bill can run low.
Insurance. Count every policy the lender will require. In Florida that can mean wind and flood coverage on top of the main policy. Get a quote before you make an offer.
HOA or condo dues. Use the current monthly dues. If the building has a special assessment, add its monthly share.

How to read your result

The big number is the ratio. Above 1.00, the rent brings in more than the payment. Below 1.00, the owner makes up the difference each month. The rent-minus-payment line shows the same gap in dollars. Your real cash flow will be lower once you count repairs, vacancy and management.

By default the calculator compares your ratio with break-even. If a lender has already told you the minimum for its program, tap A lender’s figure and type it in. We don’t list typical minimums here. Each lender sets its own, for each program, and they change often.

A higher ratio generally gives you more lenders to choose from and better pricing. A ratio near or below break-even narrows the field. It doesn’t always end the conversation, though, because the rest of the file counts too.

Why a lender’s number can differ from yours

Your result is only as good as the numbers you enter, and a lender runs its own. These are the usual reasons the two don’t match:

Rent. The lender may use the appraiser’s market rent instead of your lease, or the lower of the two.
Short-term rentals. Some lenders count past short-term rental income. Others use only long-term market rent.
The payment. Some programs figure the ratio on an interest-only payment. Others use the full payment with principal.
Taxes and insurance. The lender uses its own tax estimate and your actual insurance quote, which may not match what you typed.
Dues and assessments. Condo dues and any special assessment count once the lender knows about them.

Ways to improve a tight ratio

If the number comes out lower than you hoped, these are the usual levers. Each one has a cost, so run the numbers both ways.

Borrow less. A larger down payment shrinks the loan and the payment.
Buy down the rate. Paying points at closing lowers the payment. Weigh the cost against how long you’ll keep the loan.
Ask about interest-only. Where a program offers it and figures the ratio on that payment, the ratio goes up. You also won’t pay down the loan during that period.
Shop the insurance. In Florida, insurance can move the ratio more than people expect.
Back up the rent. If the appraiser’s rent estimate looks low, comparable leases nearby can support a second look.
Pick a different property. Sometimes the honest answer is that the rent doesn’t support the price.

What this calculator doesn’t check

The ratio is one part of a DSCR file. Lenders also review your credit, the cash you have for the down payment and reserves, the property type and condition, and, for a condo, the building itself. They also look at how you’ll hold the property, in your own name or in an LLC. A strong ratio helps, but it isn’t an approval.

For the full method behind the number, see our guide on how to calculate DSCR. For what the loan itself involves, read What is a DSCR loan? DSCR loans here cover rentals with one to four units. Five or more units is commercial lending, which our sister site handles: commercial loans on JumboLoan.com.

Frequently asked questions

What is a DSCR loan calculator?

A tool that works out a rental property’s debt service coverage ratio: the monthly rent divided by the full monthly payment. DSCR lenders start with this ratio when they review a loan, so it’s a quick way to see whether the rent covers the payment.

How do you calculate DSCR?

Divide the monthly rent by the full monthly payment: principal, interest, property taxes, insurance and any association dues. Rent that matches the payment gives 1.00. More rent gives a higher number, and less rent gives a lower one.

What is a good DSCR?

There isn’t one number. 1.00 is break-even. Each lender sets its own minimum for each program, and in general a higher ratio means more lenders to choose from and better pricing. An MLO can tell you where your ratio lands with the lenders we work with.

Does the calculator use PITIA or just principal and interest?

PITIA: principal, interest, taxes, insurance and association dues. That’s the payment most DSCR lenders look at. If a lender figures the payment another way, its ratio will differ from yours.

Why doesn’t my number match the lender’s?

The lender may use the appraiser’s market rent instead of your lease, its own tax estimate, your actual insurance quote, or an interest-only payment. Any of those can move the ratio up or down.

Can I use a DSCR loan for a cash-out refinance?

Many DSCR programs allow a cash-out refinance on a rental, and the ratio is figured the same way, on the new payment. Each lender sets its own cash-out rules.

How many DSCR loans can I get?

There’s no single limit. Each lender sets its own rules on how many loans and properties it will finance for one borrower, and many DSCR lenders work with investors who own a lot of rentals. Conventional loans, by contrast, cap financed properties under agency rules.
