Common Questions (Before You Email)

"Can you recommend a DSCR lender?"

We don't recommend specific lenders — we're not a broker or advisor. However, our DSCR Loan Requirements guide lists many of the major DSCR lenders to research.

"Why is my DSCR calculation different from another calculator?"

Different calculators make different assumptions about how lenders calculate NOI and debt service. Our calculator follows standard lender methodology (gross rent × (1 − vacancy) − operating expenses) but each lender has its own tweaks. Always confirm with your actual lender's underwriting.

"Can I use these calculators for commercial loans?"

Our calculators are designed for residential investment property (1-4 units). Commercial loans (5+ units, mixed-use, etc.) use different DSCR formulas and lender criteria. For commercial, consult a commercial mortgage broker.

"Do you offer your calculator as an embed or API?"

Not currently, but it's on our roadmap. Email us if you're interested in embedding our calculator on your site.

Stay Updated

We don't have a newsletter yet (it's on the roadmap). For now, the best way to know when we add new calculators is to bookmark dscrformulas.com and check back occasionally.

Important: We cannot provide personalized financial, tax, or investment advice. If you need professional guidance, please consult a qualified accountant, financial advisor, or real estate attorney in your jurisdiction.
