DSCR Calculator

Estimate DSCR for an investment property using purchase price, expected rent, and housing costs.

Estimated DSCR

Loan Term

Illustrative estimate only. Most DSCR lenders require 20–25% down minimum. DSCR underwriting varies by lender and may treat vacancy, taxes, insurance, reserves, and lease income differently from this simplified model. Not a loan offer.

How this calculator works

Move the sliders to test scenarios, or tap any blue value pill to type an exact number. The headline result and supporting detail pills update live as you change inputs so you can compare options without resetting your work.

Methodology: DSCR = expected monthly rent ÷ PITIA, where PITIA includes principal & interest on the financed loan, plus property taxes, insurance, and HOA dues. P&I uses standard fixed-rate amortization at the chosen rate and term. Property taxes are estimated from the tax-rate input, insurance is added from the monthly insurance input, and both fields start with preset default figures for a quick estimate. Max Loan mode solves for the largest loan whose PITIA produces a DSCR of 1.25 at the entered rent and term.

Worked example: Purchase price $350,000, 25% down, 7.5% rate, $2,800 rent, 30-yr, 1.1% taxes, $146 monthly insurance, no HOA: loan $262,500; P&I ≈ $1,835; taxes ≈ $321; insurance = $146; PITIA ≈ $2,302; DSCR = $2,800 ÷ $2,302 ≈ 1.22.

Use these estimates to compare options and prepare questions for a lender. Final pricing, eligibility, and approval depend on a full application and lender review.

Key Takeaways

  • Debt service coverage ratio (DSCR) compares expected monthly rent with monthly PITIA, which includes principal and interest, taxes, insurance, and HOA dues.
  • A ratio above 1.00 means expected rent is higher than estimated PITIA, while a ratio below 1.00 means the opposite.
  • Max Loan mode solves for the largest loan that still produces a DSCR of 1.25 under the calculator’s assumptions.

How to Use the DSCR Calculator

Use the calculator above to estimate a property’s debt service coverage ratio (DSCR) and see whether the expected rent appears to support the financing you are considering.

It's a quick way to screen an investment scenario before you get deep into quotes, appraisals, or formal underwriting.

Input What It Means Why It Matters
Expected monthly rent The gross rent used in the ratio This is the income side of the calculation.
Loan amount, rate, and term The financing terms used for principal and interest These drive the P&I portion of PITIA.
Taxes and insurance The amount of property taxes and insurance you expect to pay on the property Taxes and insurance can vary widely depending on where you live, and directly matter for PITIA.
HOA dues Any monthly association dues These are added directly to PITIA.

How Does The DSCR Calculator Work?

A DSCR loan is an investment-property, non-QM mortgage that focuses on whether the property’s expected rent can cover its housing expense.

In this calculator, the ratio is monthly rent divided by monthly PITIA. PITIA means principal and interest, property taxes, insurance, and association dues.

The higher the ratio, the more room there is between expected rent and the estimated monthly housing expense.

A DSCR of 1.00 means rent exactly covers PITIA. A DSCR above 1.00 means estimated rent is higher than estimated PITIA.

How To Calculate DSCR

The basic calculation is expected monthly rent divided by monthly PITIA. If the property is expected to rent for $3,000 per month and PITIA is $2,400, the DSCR is 1.25.

To estimate PITIA, the calculator first determines principal and interest from the loan amount, interest rate, and term. Then it factors in your property taxes and insurance estimate, as well as any HOA dues.

This is a fast screening tool to get an idea of what your DSCR might be

 It does not replace a lender’s full underwriting review, appraiser rent analysis, or reserve requirements, but it gives you a quick way to test whether a property looks plausible at the price and rent you entered.

How Max Loan Mode Works

In Max Loan mode, the calculator works backward. Instead of starting with a loan amount, it solves for the largest loan whose PITIA still produces a DSCR of 1.25 at the entered rent, rate, term, taxes-and-insurance estimate, and HOA dues.

That makes it a useful planning tool for investors who know the target rent and want to see how much leverage the property may support under the assumptions built into the model.

Because rent, taxes, insurance, and HOA costs can change, the result should be treated as an estimate, not a commitment. Small changes in rent or expenses can move the maximum supportable loan amount meaningfully.

What The Calculator Can And Cannot Tell You

The calculator helps you compare properties, test rent assumptions, and see how close a deal is to a target ratio. It is especially useful when you want a quick answer about whether a property may pencil before you request a quote.

It cannot confirm program eligibility, verify market rent, or predict the exact expense treatment a lender will use. Many real-world DSCR loans also consider reserves, vacancy assumptions, appraisal results, and program-specific minimum ratios.

Bottom Line

Our DSCR calculator is best used as an early screening tool. It helps you test whether projected rent reasonably supports the property’s estimated monthly housing cost and whether the deal still works when you change the loan terms or expense assumptions.

FAQ

What Does DSCR Stand For?

DSCR stands for debt service coverage ratio. It measures how the property’s expected income compares with its housing expense.

What Is A Good DSCR?

In general, higher is stronger because it means expected rent covers more of the property’s monthly housing cost. This calculator uses 1.25 in Max Loan mode as a target threshold.

What Is Included In PITIA?

PITIA includes principal and interest, property taxes, homeowners insurance, and HOA dues when applicable.

Can A DSCR Calculator Replace Lender Underwriting?

No. It is a planning tool. A lender may use different rent documentation, expense assumptions, or ratio requirements
