Meet Jordan.

He's been house hunting for 6 months.

Sees perfect houses online. Drives by neighborhoods. Dreams about backyards.

But won't talk to a lender because: "I don't want to get rejected."

How much can he actually afford? No idea.

Would he qualify? "Probably not..."

What's his DTI? "My what?"

Then he spent 60 seconds with a DTI ratio calculator.

Here's what changed:

Before (6 months of uncertainty):

  • Avoided lenders (fear of rejection)
  • No idea if houses he liked were affordable
  • Guessed he "probably" couldn't qualify
  • Paralyzed by not knowing

After (60 seconds with calculator):

What changed?

Not his income. Not his debt. Not his credit.

Just 60 seconds of clarity replacing 6 months of fear.

But the discoveries get even better...

Here are the 7 specific things you'll discover in the next 60 seconds.


Discovery 1: Your Actual DTI (Both Numbers)

What You Think vs What the Bank Calculates

Tyler's story:

"I did the math. My debt is $1,200 and I make $6,000/month. That's 20%, right?"

Wrong.

Tyler enters into calculator:

Calculator shows:

Front-End DTI (Housing Only):

Back-End DTI (All Debt):

  • Housing + other debt: $1,850 + $1,200 = $3,050
  • Calculation: $3,050 ÷ $6,000 = 50.8%
  • Benchmark: 43% (max for most loans)
  • Status: ❌ TOO HIGH - LIKELY DENIAL

Tyler's reaction: "Wait, I thought I was at 20%!"

The Confusion

Tyler calculated: Current debt only ($1,200 ÷ $6,000 = 20%)

Bank calculates: Current debt PLUS proposed mortgage ($3,050 ÷ $6,000 = 50.8%)

The "Aha Moment"

Most people calculate their current DTI without the mortgage.

But banks calculate your FUTURE DTI with the mortgage included.

That's the number that matters for approval.

What you discover in 60 seconds:

Both DTI ratios:

  • Front-end (housing only): The 28% target
  • Back-end (total debt): The 43% ceiling

And you see BOTH compared to actual lender benchmarks:

  • ✅ Excellent (under 36%)
  • ⚠️ Acceptable (36-43%)
  • ❌ Too High (over 43%)

Discovery 1: You see both DTI numbers lenders evaluate (not just the one you calculated wrong).


Discovery 2: Your Mortgage Qualification Status

From "Maybe?" to "Here's Exactly Where You Stand"

Rachel's situation:

Income: $75,000/year ($6,250/month)

Debts: $850/month

Wants to know: "Would I get approved?"

Calculator shows:

Qualification Matrix

FHA31%43%38%✓ Qualified
VANo limit41%38%✓ Qualified
USDA29%41%38%✓ Qualified
Jumbo28%36%38%Need to improve

What Rachel Discovers

She DOES qualify for most loans:

  • Conventional: Yes (with acceptable DTI)
  • FHA: Yes (comfortably under 43%)
  • VA: Yes (if veteran/active duty)

She does NOT qualify for:

  • Ideal conventional terms (need DTI under 36%)
  • Jumbo loans (need DTI under 36%)

The Interest Rate Impact

Calculator also shows:

  • Current DTI (38%): Estimated rate 6.875%
  • If improved to 35%: Estimated rate 6.625%
  • Difference: 0.25% = $52/month = $18,720 over 30 years

The Action Plan

To get best rates:

Discovery 2: You know your exact qualification status for every loan type (and what it would take to improve).


Discovery 3: Maximum Affordable Home Price

The Number Everyone Wants to Know

Marcus's question:

"I make $80k and have $600 in monthly debts. How much house can I afford?"

His guess: "Maybe $300k?"

Calculator shows:

At 43% DTI (Maximum):

  • Gross monthly income: $6,667
  • Maximum total obligations: $6,667 × 43% = $2,867
  • Current debt: $600
  • Available for housing: $2,867 - $600 = $2,267/month
  • Maximum home price: approximately $440,000

At 36% DTI (Ideal):

  • Maximum total obligations: $6,667 × 36% = $2,400
  • Current debt: $600
  • Available for housing: $2,400 - $600 = $1,800/month
  • Maximum home price: approximately $350,000

Marcus's reaction: "I can afford $440k?! I've been looking at $250k houses!"

The Detailed Breakdown

Calculator shows monthly payment breakdown for $440k home:

With $600 existing debt:

  • Total monthly obligations: $3,273
  • DTI: $3,273 ÷ $6,667 = 49%
  • Status: Over limit

The Refinement

Calculator lets Marcus adjust:

Scenario 1: Increase down payment to 20%

  • PMI eliminated: -$183/month
  • New total: $3,090
  • DTI: 46% (still too high)

Scenario 2: Lower home price to $410k

  • Lower mortgage payment: -$150/month
  • New total: $3,123
  • DTI: 47% (still too high)

Scenario 3: Pay off $250/month in debt first

  • Debt reduced from $600 to $350
  • Total: $3,023
  • DTI: 45% (still too high, but closer)

Scenario 4: Combination approach

  • Lower home price to $380k
  • Pay off $250/month debt
  • 20% down payment
  • DTI: 41% ✅ QUALIFIED

Discovery 3: You see your maximum home price AND what adjustments would make it work.


Discovery 4: Which Debts to Pay Off First

The Strategic Elimination Priority List

Sarah's debt:

She has $8,000 to put toward debt payoff before applying for mortgage.

Her debts:

  1. Credit Card A: $5,500 balance, $165/month minimum, 22% APR
  2. Credit Card B: $3,800 balance, $114/month minimum, 19% APR
  3. Auto Loan: $16,000 balance, $380/month payment, 5% APR
  4. Student Loans: $28,000 balance, $295/month payment, 4.5% APR
  5. Personal Loan: $6,200 balance, $215/month payment, 9% APR

Traditional advice: Pay off highest interest first (Credit Card A at 22%)

Calculator shows DTI Impact Ranking:

DebtTo EliminateMonthly Payment FreedDTI Impact ScoreBuying Power Gain
Credit Card B$3,800$1143.0%$22,800
Personal Loan$6,200$2153.5%$43,000
Credit Card A$5,500$1653.0%$33,000
Student Loans$28,000$2951.05%N/A (can't fully pay)
Auto Loan$16,000$3802.4%N/A (can't fully pay)

Strategic Plan

Option 1: Maximum Impact with $8,000

  • Pay off Personal Loan: $6,200 (frees $215/month)
  • Pay off Credit Card B: $1,800 remaining (partial, doesn't eliminate payment)
  • Result: $215/month freed = $43,000 buying power

Option 2: Eliminate Two Accounts

  • Pay off Credit Card B: $3,800 (frees $114/month)
  • Pay off remaining $4,200 toward Credit Card A (doesn't eliminate fully)
  • Result: $114/month freed = $22,800 buying power

Option 3: Wait 2 months, save $2,200 more

  • Total available: $10,200
  • Pay off Personal Loan: $6,200
  • Pay off Credit Card B: $3,800
  • Remaining: $200 toward Credit Card A
  • Result: $329/month freed = $65,800 buying power

Calculator recommendation: Option 3

Wait 2 months, eliminate TWO accounts, maximize DTI impact.

Discovery 5: The What-If Scenarios

Instant Scenario Testing

Lisa's questions:

  1. "What if I paid off my car loan?"
  2. "What if I got a $10k raise?"
  3. "What if I made a larger down payment?"
  4. "What if I combined debt payoff AND income increase?"

In her head: "This would take hours to figure out..."

In the calculator: 30 seconds per scenario.


Scenario 1: Pay off $380/month car loan

Current situation:

  • Income: $6,500/month
  • Debt: $1,100/month (including $380 car)
  • DTI: 43%
  • Max home: $320,000

After paying off car:

  • Income: $6,500/month
  • Debt: $720/month
  • DTI: 38%
  • Max home: $395,000
  • Buying power increase: $75,000

Scenario 2: Get $10k raise ($833/month increase)

Current: DTI 43%, max home $320k

After raise:

  • Income: $7,333/month
  • Debt: $1,100/month (unchanged)
  • DTI: 38%
  • Max home: $390,000
  • Buying power increase: $70,000

Scenario 3: Increase down payment from 10% to 20%

Current: 10% down ($32k), PMI $133/month, DTI 43%

After: 20% down ($64k), no PMI, DTI 41%

  • PMI eliminated saves $133/month in housing costs
  • Buying power increase: $25,000 (less impactful than debt/income)

Scenario 4: COMBO (pay off car + get raise)

  • Income: $7,333/month (+$833)
  • Debt: $720/month (-$380)
  • DTI: 29% (excellent!)
  • Max home: $510,000
  • Buying power increase: $190,000

The Power

Lisa can test every scenario in seconds and see EXACT impact on:

  • DTI percentage
  • Qualification status
  • Maximum home price
  • Monthly payment

Discovery 5: You test every "what if" instantly and see exact dollar impact.


Discovery 6: Your Qualification Timeline

From "Someday" to a Specific Month

David's situation:

Current DTI: 47% (too high)

Target DTI: 36% (ideal)

Calculator shows:

Current Status

  • Monthly debt to eliminate: $367
  • Total debt to pay off: approximately $7,340
  • At current debt payoff rate ($500/month): 15 months

Timeline Projection

MonthDebt PaidRemaining DebtDTIStatus

The Milestone View

  • Month 6 (February 2026): Can start applying for mortgages
  • Month 9 (May 2026): Qualify for best rates
  • Month 12 (August 2026): Maximum buying power achieved

Acceleration Options

If David increases debt payoff to $800/month:

  • Reaches 43% DTI: Month 2
  • Reaches 36% DTI: Month 5
  • Accelerated timeline: 4 months faster

If David gets $500/month raise instead:

  • DTI drops to 41% immediately (income increase)
  • Combine with $500/month debt payoff
  • Reaches 36% DTI: Month 4
  • Accelerated timeline: 5 months faster

Discovery 6: Your qualification gets a real timeline, not a vague "eventually."


Discovery 7: Your Hidden Buying Power Loss

The Cost of Every Monthly Payment

Emma's revelation:

She knew she had debt. She didn't know what it was COSTING her.

Calculator shows "Buying Power Impact":

DebtMonthly PaymentBuying Power Loss
Credit Card 1$120-$24,000
Credit Card 2$85-$17,000
Auto Loan$425-$85,000
Student Loans$310-$62,000
Personal Loan$180-$36,000
TOTAL$1,120-$224,000

Emma's reaction: "My debt is costing me $224,000 in buying power?!"

The Visual Impact

Calculator shows side-by-side comparison:

Current Situation (with debt):

  • Income: $7,000/month
  • Debt: $1,120/month
  • Max home: $276,000

If Debt Were Eliminated:

  • Income: $7,000/month (same)
  • Debt: $0/month
  • Max home: $500,000

Difference: $224,000

That's not theoretical. That's the ACTUAL difference between:

  • The $276k home she qualifies for now
  • The $500k home she COULD qualify for with zero debt

The Per-Dollar Impact

Every $100/month in debt = approximately $20,000 less buying power

Emma's small debts add up:

  • $120 credit card = -$24k home value
  • $85 credit card = -$17k home value
  • Even "small" debts have massive impact

Discovery 7: You see exactly how much buying power each debt is stealing (not just the monthly payment).
