Learn DSCR the way Canadian lenders underwrite it: formula, “good” ranges, common add-backs, and what counts as debt service—plus a free DSCR calculator.
DSCR (Debt Service Coverage Ratio) is one of the fastest ways Canadian lenders decide whether your business can safely handle new debt. In plain terms, DSCR answers one question: “After running the business, do you have enough cash flow to make the payments—with a buffer?”
Use Mehmi’s free DSCR calculator to run your numbers first, then use this guide to understand what lenders will accept, what they’ll adjust, and how to improve your DSCR before you apply:

Key point: DSCR measures how comfortably your cash flow covers your required debt payments.
BDC defines DSCR as EBITDA divided by principal and interest, and uses it to assess debt capacity. BDC.ca
Most lenders treat DSCR as a “quick risk filter.” If DSCR is strong, you usually get smoother approvals, higher limits, and better structures. If DSCR is thin, lenders either reduce the amount, shorten the term, ask for more equity, or add conditions.
Key point: The formula is simple—but the inputs (EBITDA and “debt service”) are where deals get won or lost.
DSCR = EBITDA ÷ (Annual principal + Annual interest)
BDC’s glossary uses this approach directly. BDC.ca
Lenders may use different numerator/denominator definitions depending on the product:
This is why two lenders can look at the same company and arrive at different “max loan” sizes.
Key point: There’s no single universal threshold, but 1.25× is a common comfort benchmark in Canadian business conversations.
RBC describes DSCR as a key measure for repayment ability and notes that the greater the value over 1.25 (125% coverage), the better, while also acknowledging different debt providers prefer different numbers. RBC Royal Bank+1
Here’s a practical interpretation you can use when you’re planning financing:
<table><thead><tr><th>DSCR range</th><th>How lenders often react</th><th>What it usually means for you</th></tr></thead><tbody><tr><td>< 1.00×</td><td>High-risk / restructure territory</td><td>Payment only works if everything goes right</td></tr><tr><td>1.00×–1.15×</td><td>Possible, but tight and structure-dependent</td><td>Expect lower limits, more security, or more equity</td></tr><tr><td>1.15×–1.25×</td><td>“Borderline okay” for many deals</td><td>Approval depends on collateral, stability, and story</td></tr><tr><td>1.25×+</td><td>Comfort zone</td><td>More options and cleaner approvals :contentReference[oaicite:3]{index=3}</td></tr></tbody></table>
Important nuance: DSCR expectations can differ by industry volatility, collateral, and lender type. Even Canadian regulators reference DSCR among the financial ratios used in bank-style risk assessments in certain contexts (e.g., project-style credit risk frameworks). osfi-bsif.gc.ca
Key point: DSCR is the headline inside “capacity,” but lenders still underwrite the full story.
A common credit framework is the 5Cs—character, capacity, capital, collateral, and conditions—and “capacity” is where DSCR lives.

What that means in real underwriting terms:
And when lenders approve a deal, they often formalize monitoring via covenants and conditions precedent—conditions precedent must be met before funds are advanced, and covenants let the bank monitor performance after money is lent.

Key point: Your lender’s EBITDA is usually normalized EBITDA, not your accountant’s line item.
BDC’s DSCR definition explicitly uses EBITDA as the numerator. BDC.ca
But lenders will often normalize it to reflect ongoing earning power.
Pro tip: If you want an EBITDA number you can defend in underwriting, start with a calculator and then document each add-back with receipts and a one-line explanation:

Key point: This is where most borrowers accidentally overestimate their DSCR.
At minimum, debt service usually includes:
But lenders may also consider:
If you’re equipment-heavy, DSCR can look “fine” while your real cash flow is tight—because DSCR (pure) may not fully capture fixed lease obligations the way an FCCR view would. That’s why financing structure matters.
If you’re buying equipment, compare the payment impact using:
https://www.mehmigroup.com/calculators/equipment-calculator
…and don’t default to a generic term loan if the asset can support an equipment-first structure:

Key point: You can estimate DSCR in 10–15 minutes with basic financials—then refine it before applying.
Include every obligation that behaves like a fixed payment:

…and for “rate shock” or prepayment modeling:

Key point: Most DSCR problems aren’t math problems—they’re definition and planning problems.
A lender cares about your ability to pay in the boring months.
A new payment doesn’t replace your existing payment load unless you’re actually paying something off.
DSCR lives inside the 5Cs—if collateral, conditions, or character are weak, you still may need more equity or a smaller facility.

Stacking multiple weekly/daily repayment products can make your “monthly DSCR” look fine while your cash account is constantly under pressure.
Key point: DSCR improves fastest when you either increase sustainable EBITDA, reduce required payments, or both.
Here are lender-friendly levers that actually work:
If payment pressure is the real problem, test refinance scenarios here:

If you’re trying to estimate what you can realistically finance on equipment without blowing up DSCR:

Sometimes the cleanest fix is a bigger down payment, retained earnings, or a staged purchase plan.
If you want to include the “timing reality” lenders often sniff out from bank statements (NSFs, big remittance weeks, seasonal troughs), pair DSCR with a cash timing view:

Business: 14-person Ontario metal fab shop (owner-managed)
Goal: Buy a CNC upgrade to increase throughput and reduce outsourced work
Problem: The business could qualify on paper, but the initial structure made DSCR too tight once all obligations were included.
Starting numbers (simplified):
Initial DSCR: $520k ÷ ($360k + $120k) = 1.08× (tight)
What changed (the DSCR fix):
Result: DSCR moved from “barely works” to “lender-comfortable,” and the file was easier to approve because the structure matched the risk.
If you want to compare structures for your own deal, start here:

Key point: Your best move is to calculate DSCR early, then structure the request around a payment you can carry in slow months.
If you want a second set of eyes on DSCR, structure, and documentation, Mehmi can help you map the cleanest approval path without over-borrowing.
No. Debt-to-income is more consumer-focused. DSCR is a business cash-flow coverage ratio used by lenders to assess repayment ability. BDC.ca
It varies by lender and risk, but many lenders prefer DSCR above 1.25× as a comfort benchmark (higher is better). RBC Royal Bank+1
Often yes—either directly (if treated debt-like) or indirectly through fixed-charge coverage. If you’re equipment-heavy, structure matters as much as the ratio.
Sometimes—usually with mitigants (more collateral, more equity, smaller request, shorter term, or a refinance/restructure plan). DSCR under 1.0 signals the payment doesn’t fit current cash flow.
They may use different definitions of EBITDA, include/exclude certain obligations, or use different risk models. Even bank-style credit frameworks reference DSCR among ratios used in risk assessments in certain lending contexts. osfi-bsif.gc.ca
Reduce payment (structure/term/refi), increase sustainable EBITDA (pricing/margins/collections), or add equity—ideally with a structure that matches the asset and your cash cycle.
