What Dscr Calculator does
The DSCR Calculator on Altyst helps real estate investors and commercial lenders evaluate income-producing properties by computing the Debt Service Coverage Ratio. Users enter any two of the three core figures—Net Operating Income (NOI), annual debt service, or DSCR—and the tool solves for the third. Beyond the basic ratio, the page computes the monthly payment from a loan quote, determines how much NOI can decline before hitting common covenant thresholds, and presents the covenant number showing dollars of income behind each dollar of payment. The interface displays results in clear rows with labeled fields, making it easy to compare scenarios or assess risk. Free access requires no signup or email, and the tool is designed to mirror how lenders underwrite loans, from initial sizing to ongoing covenant testing.
