Before you rely on this

Covers principal and interest only. Prepayment penalties, stamp duty, guarantee fees and registration costs are excluded, and a variable-rate loan is re-amortized at every rate change, so the remaining schedule will differ from this table.

Real-World Scenarios & Practical Cases

3 Practical CasesScenario #1

30-Year $300,000 Home Mortgage Comparison

At 4.5% rate: Equal Payment yields fixed $1,520/month ($247k total interest). Equal Principal starts at $2,041/month and decreases ($230k total interest), saving ~$16,600 in lifetime interest.

Equal principal reduces total interest cost if early cash flow allows higher initial payments.Scenario #2

Interest-Only Personal Line of Credit

A $50,000 loan at 5.0% interest-only requires $208/month. Minimal monthly cash drain, but full principal remains due at maturity.

Best suited for short-term liquidity management.Scenario #3

Early Principal Prepayment Strategy

Making a $20,000 lump sum prepayment in year 5 drastically reduces total interest and shorten term duration.

Check for early prepayment fee waivers (typically after 3 years).Amortized payment formulaMonthly Payment = [P × r × (1+r)^n] / [(1+r)^n - 1] (P: Loan Amount, r: Monthly Rate, n: Months)

Pro Tips & Key Considerations
