Frequently Asked Questions
What is compound interest?
Compound interest means you earn returns on both your original investment and previously accumulated returns. Over time this creates exponential growth. Daily compounding grows slightly faster than monthly, which grows faster than annual.
How does a loan calculator differ from a mortgage calculator?
A loan calculator handles any general-purpose loan (personal, auto, student). The mortgage calculator adds property-specific costs like taxes and insurance, plus options for different term lengths. Both provide full amortization schedules.
What is the 4% rule for retirement?
The 4% rule suggests withdrawing 4% of your portfolio in the first year of retirement, then adjusting for inflation annually. Historically, this provided a high probability of not outliving your money over 30 years with a balanced portfolio.
Are these calculators financial advice?
No. These are mathematical planning tools for education and estimation. Actual investment returns vary, tax rules differ by jurisdiction, and personal circumstances differ. Consult a qualified financial advisor before making decisions.
