Frequently Asked Questions
1. How do you calculate monthly loan payments?
We use the standard amortization formula: M = P × [r(1 + r)^n] / [(1 + r)^n – 1]. Where M is the monthly payment, P is the principal, r is the monthly interest rate, and n is the number of payments. For example, a $100,000 loan at 5% for 10 years equals $1,060.66 per month.
2. What's the difference between fixed payment and equal principal methods?
Fixed Payment (Amortized) means the same payment every month, with early payments having more interest and later payments having more principal. Equal Principal method keeps the principal payment the same while interest decreases over time, making monthly payments decrease throughout the loan.
3. How much will I pay in total interest on my loan?
Calculate total interest by subtracting the original loan amount from the total of all payments: Total Interest = (Monthly Payment × Number of Payments) – Loan Amount. For example, $1,000/month for 60 months on a $50,000 loan = $60,000 – $50,000 = $10,000 in total interest.
4. Should I refinance my mortgage?
Refinance if your total savings after refinancing costs are positive. Our calculator shows whether refinancing saves you money by comparing your current loan payments with new terms and factoring in all refinancing costs.
5. How much do I need to save for retirement?
A starting point is the 4% rule: Annual Retirement Income Needed ÷ 0.04 = Required Savings. For example, if you need $50,000/year, you should have $1,250,000 saved. Our calculator provides more detailed projections based on your specific situation.
6. How does compound interest affect my retirement savings?
Compound interest means you earn returns on your returns. Our calculator uses the formula: FV = P(1 + r)^n + PMT × [((1 + r)^n – 1) / r] to show how your money grows over time with regular contributions.
7. What interest rate should I use for retirement planning?
Conservative estimates use 3-5% annual returns. Historical stock market averages are 7-10%, but include higher risk. Our calculator lets you test different scenarios to see how various rates affect your retirement savings.
8. How accurate are these calculations?
Our calculators use standard financial formulas used by banks and financial institutions. However, actual loan terms may include additional fees, insurance, and variable rates not included in basic calculations. Always consult with a financial advisor for personalized advice.
