Frequently Asked Questions
What's the difference between the Loan Calculator and the Mortgage Calculator?
The Loan Calculator is built for general installment loans, like a car loan or personal loan, based on principal, rate, and term. The Mortgage Calculator is built specifically for home loans and can factor in property taxes and insurance alongside the payment.
How accurate are online mortgage and loan calculators?
They give a solid estimate based on the numbers you enter, but your actual payment from a lender can differ once taxes, insurance, PMI, and closing costs are added in. Treat the result as a starting point rather than a final quote.
What's the difference between the Compound Interest Calculator and the Loan Calculator?
The Compound Interest Calculator shows how a lump sum or regular savings grows over time. The Loan Calculator works the other way around, showing how a borrowed amount gets paid down through regular installments.
Does the BMI Calculator account for muscle mass or body composition?
No. BMI is based only on height and weight, so it doesn't distinguish muscle from fat. It's a general screening number rather than a full picture of health.
What's the difference between the Basic and Scientific Calculator?
The Basic Calculator covers everyday arithmetic. The Scientific Calculator adds functions like trigonometry, logarithms, and exponents for more advanced work.
