How the Calculator Works

Renting Calculation

Formula:

Year 1: Monthly Rent × 12 + Renters Insurance × 12
Year 2: (Monthly Rent × 1.03) × 12 + Insurance × 12
Year 3: (Monthly Rent × 1.03²) × 12 + Insurance × 12
...continue for all years

Total Rent Cost = Sum of all years

Example (5 years, $2,000/month rent, 3% increases):

  • Year 1: $2,000 × 12 = $24,000
  • Year 2: $2,060 × 12 = $24,720
  • Year 3: $2,122 × 12 = $25,464
  • Year 4: $2,186 × 12 = $26,232
  • Year 5: $2,251 × 12 = $27,012
  • Total: $127,428 (plus insurance)

Buying Calculation

Components:

  1. Monthly Mortgage Payment
    • Formula: Loan Amount × [r(1+r)^n] / [(1+r)^n – 1]
    • r = monthly interest rate (annual ÷ 12)
    • n = number of payments (30 years × 12 = 360)
    • Assumes 30-year fixed mortgage
  2. Principal vs Interest Split
    • Early payments mostly interest
    • Later payments are mostly principal
    • Calculator tracks principal paid = equity gained
  3. Total Buying Costs
    • Down payment (upfront)
    • Closing costs (upfront)
    • Mortgage payments (principal + interest)
    • Property taxes (annual)
    • Home insurance (monthly)
    • Maintenance (annual % of value)
  4. Equity Calculation
    • Down payment + Principal paid over the timeframe
    • This amount is subtracted from the total costs
    • Represents wealth buildup
  5. Net Buying Cost
    • Total costs – Equity gained
    • This is what you “lose” (like rent)
    • Compared to the total rent cost

Example ($300,000 home, 20% down, 6.5% rate, 5 years):

  • Down payment: $60,000
  • Loan amount: $240,000
  • Monthly mortgage: $1,517 (P&I)
  • 5-year mortgage payments: $91,020
  • Principal paid in 5 years: ~$22,000
  • Property taxes (5 years): $18,000
  • Insurance (5 years): $9,000
  • Maintenance (5 years): $15,000
  • Closing costs: $8,000
  • Total costs: $201,020
  • Less equity: $82,000 (down payment + principal)
  • Net cost: $119,020

Common Mistakes to Avoid

Unrealistic Inputs

❌ Ignoring Rent Increases

  • Rent will likely increase annually
  • 3% is typical; some markets are higher
  • Factor this into the comparison

❌ Overestimating Appreciation

  • 3% is the historical average
  • Can be 0% or negative
  • Don’t assume 5%+ without evidence

❌ Underestimating Maintenance

  • 1% of home value minimum
  • Older homes need more
  • Emergencies happen (roof, HVAC)

❌ Forgetting Closing Costs

  • 2-5% of the purchase price
  • Significant upfront expense
  • Hard to recoup in the short term

Analysis Errors

❌ Too Short Timeframe

  • Need 5+ years to fairly compare
  • Closing costs spread over time
  • Equity needs time to build

❌ Comparing Different Quality

  • Compare similar homes
  • Rent for $2,000 ≠ $500,000 purchase
  • Match bedrooms, location, and size

❌ Ignoring Opportunity Cost

  • The down payment could be invested
  • Consider alternative returns
  • Stock market historical: 7-10% annually

❌ Only Looking at Payment

  • “My mortgage is less than rent!”
  • Must include ALL costs
  • Factor in the equity gained

Personal Situation Errors

❌ Buying When Not Ready

  • Need a stable income
  • 20% down avoids PMI
  • Emergency fund essential
  • Good credit important

❌ Not Considering Lifestyle

  • The job may require relocation
  • Life changes coming
  • Value flexibility highly
