Uniform series F/A calculator

Accumulate equal end-of-period deposits to their balance at the last payment date.

F=A×[(1+i)n−1]iF = \frac{A \times \left[\left(1 + i\right)^{n} - 1\right]}{i}

Worked example

Given

  • AA = 100 $/period
  • ii = 0.08 decimal
  • nn = 10 periods
F=100×[(1+0.08)10−1]0.08≈1,449F = \frac{100 \times \left[\left(1 + 0.08\right)^{10} - 1\right]}{0.08} \approx 1{,}449
