Our tool uses the future value of an annuity formula for compound interest with annual contributions:
FV = P × ((1 + r)ⁿ - 1) / r + C × (1 + r)ⁿ
- FV: Future Value (retirement balance)
- P: Current balance
- C: Annual contribution
- r: Annual return rate (as decimal)
- n: Number of years until retirement
For inflation adjustment, we use: Real Value = FV / (1 + inflation)ⁿ
