Direct answer: a Canadian rental property ROI calculator screens a property with monthly cash flow, annual net operating income, cap rate, cash-on-cash return and DSCR. A deal can show positive NOI but still lose cash after financing, so the metrics need to be read together.
Enter purchase price, down payment, interest rate, rent, operating expenses and vacancy to test a rental before making an offer. The result is a pre-tax planning estimate, not lender approval, tax advice or a full appraisal.

| Cap rate | Annual NOI / purchase price | Compares property yield before debt service. |
| Cash flow | Effective rent - mortgage payment - operating expenses | Shows monthly pre-tax carrying result. |
| Cash-on-cash return | Annual cash flow / down payment | Compares cash flow with cash invested. |
| DSCR | Annual NOI / annual mortgage payments | Screens debt-service coverage before lender overlays. |

Methodology: the mortgage payment uses the same Canadian semi-annual compounding convention as the main mortgage calculator, then calculates effective rent after vacancy, NOI after operating expenses, cap rate before financing, pre-tax cash flow after debt service, cash-on-cash return against down payment, and DSCR as NOI divided by annual debt service.
Limitations: this calculator does not model income tax, CCA, repairs beyond the monthly expense assumption, condo special assessments, insurance underwriting, rent-control rules, municipal licensing, refinancing, appraisal gaps, lender overlays or sale proceeds. DSCR is a screening metric only; lender policies differ by product and borrower.
