Financial Planning Guide

Mortgage Planning

A mortgage is typically the largest financial commitment you'll make. Our mortgage calculators help you understand:

  • Monthly Payment Calculation: Principal, interest, taxes, and insurance (PITI)
  • Down Payment Impact: How much to put down to avoid PMI
  • Amortization: How payments split between principal and interest over time
  • Extra Payment Benefits: How additional payments save thousands in interest
Example: On a $400,000 home with 20% down, a 6.5% interest rate results in $2,022/month for principal and interest alone. Add property taxes (~$400/month) and insurance (~$100/month) for a total monthly payment around $2,522.

Investment Growth

Understanding compound interest is crucial for building wealth. Our investment calculators demonstrate:

  • Compound Growth: How money grows exponentially over time
  • Regular Contributions: The power of consistent monthly investing
  • Time Value: Why starting early makes a massive difference
  • Risk vs. Return: How different return rates affect outcomes
Example: Investing $500/month for 30 years at 7% annual return grows to $610,000. The same amount for 40 years grows to $1.31 million—demonstrating why starting early is crucial.

Retirement Planning

Retirement planning requires understanding multiple factors:

  • Retirement Goal: How much you need based on desired lifestyle
  • Savings Rate: How much to save monthly to reach your goal
  • Employer Matching: Taking full advantage of 401(k) matches
  • Inflation Impact: How rising costs affect retirement needs
Rule of Thumb: Most experts recommend saving 10-15% of income for retirement. If you start at 25 and want $1 million by 65, you need to save about $380/month assuming 7% returns.

Debt Management

Managing loans effectively can save thousands in interest:

  • Loan Comparison: Understanding APR vs. interest rate
  • Extra Payments: How additional payments reduce total interest
  • Refinancing: When it makes sense to refinance
  • Debt Avalanche: Paying off highest interest debts first
Example: A $25,000 auto loan at 5% for 5 years costs $471/month. Adding just $50/month extra saves $1,247 in interest and pays off the loan 8 months early.

Frequently Asked Questions

Use our Advanced Mortgage Calculator by entering:

  • Loan Amount: Home price minus down payment
  • Interest Rate: Annual percentage rate from your lender
  • Loan Term: Usually 15 or 30 years
  • Additional Costs: Property taxes, insurance, PMI
Real Example: $400,000 home, 20% down ($80,000), leaves $320,000 loan at 6.5% for 30 years = $2,022/month principal and interest. Add $400/month property taxes + $100/month insurance = $2,522/month total.

Simple Interest: Calculated only on the principal amount

Compound Interest: Calculated on principal plus accumulated interest (interest earning interest)

Example with $10,000 at 5% annual interest:
Simple Interest: Earns $500 every year consistently
Compound Interest: Year 1: $500, Year 2: $525, Year 3: $551.25, growing exponentially
After 20 years: Simple = $20,000, Compound = $26,533

Financial experts recommend saving 10-15% of your income for retirement. Use our Retirement Calculator to get personalized results.

Age-Based Guidelines:
Age 30: Have 1x annual salary saved
Age 40: Have 3x annual salary saved
Age 50: Have 6x annual salary saved
Age 60: Have 8x annual salary saved

Example: If you're 25, earn $60,000, and want $1M at retirement, save approximately $350/month assuming 7% returns.

Extra mortgage payments can save significant interest, but consider your complete financial picture first.

Real Example: $300,000 mortgage at 6% for 30 years
Regular payments: $1,799/month, total interest: $347,515
Adding $200/month extra: Saves $153,813 in interest and pays off loan 9 years early

Consider first: Emergency fund, high-interest debt, employer 401(k) match, investment opportunities with higher returns

Take-home pay depends on federal taxes, state taxes, Social Security, Medicare, and other deductions. Use our Salary Calculator for accurate results.

Example: $75,000 salary in California (single filer)
Gross Pay: $75,000
Federal Tax: ~$8,600
State Tax: ~$3,400
Social Security: ~$4,650
Medicare: ~$1,090
Take-Home: ~$57,260 (76% of gross)
