How the calculation works
Future value = current × (1+r)^n + monthly × [((1+r)^n − 1) ÷ r] where r = monthly rate, n = total months.
Example: 50,000 current, 500/month, 7% for 20 years ≈ 420,000.
How financial calculations work
Most finance calculators use standard formulas: amortization for loans, compound interest for savings, and present/future value for investments. Results are estimates — actual terms may vary based on lender fees, credit score, taxes, and market conditions. Always consult a financial advisor for major decisions.
Understanding key financial terms
APR (Annual Percentage Rate) includes fees and interest. APY (Annual Percentage Yield) reflects compound interest. DTI (Debt-to-Income) ratio measures monthly debt payments against gross income. Lenders typically prefer DTI below 36%. CAGR (Compound Annual Growth Rate) smooths investment returns over time.
Important limitations
This tool provides a mathematical estimate based only on the values entered. It does not account for regulations, taxes, lender fees, market conditions, or individual circumstances.
