How Savings Growth Is Calculated
This calculator uses the compound interest formula with regular contributions:
FV = P(1+r)^n + PMT × [(1+r)^n - 1] / r
Where P = initial deposit, PMT = monthly contribution, r = monthly rate, n = total months.
Example Calculation
$5,000 initial deposit with $200/month at 4.5% APY for 10 years.
- 01Monthly rate = 4.5% / 12 = 0.375%
- 02Months = 10 × 12 = 120
- 03Initial deposit grows to: $5,000 × 1.00375^120 = $7,834
- 04Contributions grow to: $200 × (1.00375^120 - 1) / 0.00375 = $30,038
- 05Future value = $7,834 + $30,038 = $37,872
- 06Total contributed = $5,000 + $24,000 = $29,000
- 07Interest earned = $37,872 - $29,000 = $8,872
