What to do next
Strong cushion above debt service.
Benchmark: Most DSCR lenders require 1.20–1.25 minimum coverage. — SBA 7(a) and investor-loan underwriting norms
What this means
Your coverage ratio is 1.79x — how many times operating income covers the debt payment.
Is this good or bad?
Yes — this is a strong result by U.S. standards. Strong cushion above debt service.
What's the risk?
Low risk. Nothing here needs urgent attention — protect the position you are in.
What should you do next?
Increase the down payment
Your action plan
- 1
Increase the down payment
A smaller loan raises coverage faster than raising rents or revenue.
- 2
Re-price the debt
A longer amortization lowers the annual payment used in the ratio.
- 3
Verify the income assumptions
Lenders underwrite actual documented income, not projected.
- 4
Budget for vacancy and repairs
Coverage calculated without reserves overstates the real cushion.
- 5

Units and revenue needed to cover fixed and variable costs.

DSCR Loan Calculator: Your result quantifies the KPI implied by the assumptions above. Rerun with conservative and aggressive inputs to see the plausible range.
What your result means
- A CAC:LTV ratio below 1:3 usually signals unsustainable growth economics.
- Gross margin above 60% is the software benchmark; below 40% typically means a services business.
- Break-even in units tells you the sales floor you need to cover fixed costs.
How does the formula work?
How it works
Step-by-step guide
- 1Enter your revenue, cost, or customer metrics.
- 2Set growth, margin, or retention assumptions.
- 3Review the calculated KPI and its components.
- 4Copy the result into your dashboard or investor update.
Example calculation
Example: $75k NOI on a $500k DSCR loan at 7.5%.
Who should use this calculator?
- Founders modelling revenue, CAC or LTV
- Marketing teams sizing campaign ROI
- Ops teams tracking unit economics
- Investors running quick diligence
When should you use it?
- Before launching a new campaign or product
- During monthly or quarterly business reviews
- When fundraising or building a pitch model
- Before making a hiring or pricing decision
What affects the result?
- Assumptions about growth, churn or margin
- Time period consistency (monthly vs annual)
- One-time vs recurring inputs
- Segment or cohort you're modelling
Compare three scenarios
| Scenario | Inputs | Signal |
|---|---|---|
| Early-stage SaaS | $150 CAC · $60 ARPU · 5% churn | LTV ~$1,200 · CAC:LTV ~1:8 · healthy |
| Growth SaaS | $600 CAC · $120 ARPU · 3% churn | LTV ~$4,000 · CAC:LTV ~1:6.7 · healthy |
| Struggling SaaS | $800 CAC · $50 ARPU · 8% churn | LTV ~$625 · CAC:LTV ~1.3:1 · unsustainable |

Comparison tables
Fixed vs Variable Rate: Which Costs Less?
Fixed rates lock your payment for the life of the loan. Variable (adjustable) rates start lower but move with an index such as SOFR or the Prime Rate published by the Federal Reserve.
| Factor | Fixed rate | Variable / adjustable rate |
|---|---|---|
| Starting rate (2025 typical) | Higher — around 0.25%–0.75% above the intro ARM rate | Lower teaser rate for 3, 5, 7 or 10 years |
| Payment stability | Identical principal & interest every month | Resets at each adjustment period, subject to caps |
| Best when | You keep the loan more than 5–7 years, or rates are falling slowly | You expect to sell, refinance or pay off before the first reset |
| Worst case | You overpay if market rates drop and you never refinance | Payment shock at reset — caps commonly allow +2% per adjustment, +5% lifetime |
| Disclosure rule | APR disclosed under Regulation Z (Truth in Lending) | CFPB requires a Consumer Handbook on Adjustable-Rate Mortgages (CHARM) booklet |
Bottom line: Run both scenarios in the calculator. If the total interest paid over your expected holding period is within about 1% of each other, take the fixed rate — the certainty is worth more than the small savings.
Paying Cash vs Financing
Financing is worth it only when the after-tax return on the money you keep invested beats the loan's APR.
| Factor | Pay cash | Finance the purchase |
|---|---|---|
| Total cost | Sticker price only | Price plus total interest |
| Liquidity | Drains your emergency fund | Keeps cash available |
| Break-even test | Wins whenever loan APR > your safe after-tax return | Wins when a 0% or subsidized APR is below Treasury yields |
| Credit effect | None | Builds installment history; raises DTI |
| 2025 reality check | Compare with the current 4-week Treasury bill yield | Only compelling at promotional 0%–3% APR |
Bottom line: At today's rates, financing above roughly 5% APR costs more than a risk-free Treasury pays. Below that, keeping cash invested can win — as long as you actually invest it.
Common mistakes to avoid
- Using inconsistent time periods (monthly vs annual).
- Ignoring churn or refunds when projecting revenue.
Pro tips
- Track cohort behaviour, not just aggregate metrics.
- Keep unit economics honest by including all variable costs.
- Sanity-check projections against the past 3–6 months of actuals.
Why use this calculator
- Fast unit-economics, NPV, IRR and payback checks for founders and operators.
- No spreadsheet gymnastics — just enter the numbers and read the result.
- Great for board decks, investor updates and internal planning.
- Formulas match CFA / MBA-standard finance textbooks.
Limitations to keep in mind
- Assumes inputs are accurate — garbage in, garbage out.
- Does not model competitive response, macro shocks or churn cliffs.
- Point estimates only — consider a Monte-Carlo tool for probabilistic ranges.
- Should not replace a full financial model for board or investor decisions.
Key terms explained
- CAC (Customer Acquisition Cost)
- Total sales and marketing spend divided by new customers acquired in the same period.
- LTV (Lifetime Value)
- The gross profit a customer generates across their full relationship. Healthy SaaS targets LTV:CAC of at least 3:1.
- Churn
- The % of customers or revenue lost in a period. Monthly churn above 5% usually signals a product-market-fit gap for SaaS.
- Gross margin
- Revenue minus cost of goods sold, as a % of revenue. Software is typically 70–90%; services 20–40%.
- Payback period
- How many months of gross profit are needed to recoup a customer's acquisition cost. Under 12 months is considered strong.
Before you decide
- Sanity-check the model against the last 3–6 months of actuals.
- Include all variable costs (payment fees, support, hosting) in gross margin.
- Model conservative, base, and stretch scenarios before sharing with investors.
- Track cohort-level metrics — averages hide the customers who churn fastest.
