Formula

1) বর্তমান সঞ্চয়ের ভবিষ্যৎ মূল্য = বর্তমান × (1 + r)^n, r = বার্ষিক হার ÷ 1200, n = মাস। 2) বাকি প্রয়োজন = লক্ষ্য − ভবিষ্যৎ মূল্য। 3) মাসিক সঞ্চয় = বাকি × r ÷ ((1+r)^n − 1) (r = 0 হলে বাকি ÷ n)। 4) মোট জমা = মাসিক × n। 5) অর্জিত সুদ = লক্ষ্য − বর্তমান − মোট জমা।

How the calculation works

Your current savings keep growing at the return rate, so their future value covers part of the goal on its own.

What remains is the gap the monthly deposits must fill, and the annuity formula turns that gap into a fixed monthly amount.

The interest earned is the goal minus your starting savings and everything you deposited, which shows how hard the money worked.

Common mistakes

When to use it

Worked example

To reach 1,000,000 in 60 months with 100,000 saved at 8%, save 11,582 a month.

Required monthly savings 11,582.09
Total deposits 694,925.29
Interest earned (BDT) 205,074.71

Common questions

Why is the monthly figure lower when I already have savings?

Your existing savings keep earning and grow, so they cover part of the goal.

What if I cannot save that much?

Extend the timeline or lower the target; both reduce the monthly amount.
