Savings Projector Calculator
A savings projector helps you estimate how a starting amount and regular monthly contributions may grow over time. It combines recurring deposits with compounding so you can see both the saved amount and the growth earned month by month.
What this savings projector shows
The calculator tracks opening balance, monthly contribution, monthly growth, and closing balance across each year.
This makes it easier to understand how disciplined savings habits build wealth over time instead of only seeing a final number.
Where it is useful
It works well for goal-based saving such as education funds, emergency reserves, travel planning, or a home down payment.
You can also use it to test whether increasing your monthly savings by a small amount can shorten the time needed to reach a target.
Formula Used for Savings Growth
When a savings plan includes a starting balance plus regular end-of-month additions, the projected value combines compound growth on the initial amount and the future value of a recurring series of contributions.
FV = P (1 + i)^m + PMT x [((1 + i)^m - 1) / i]
Where,
- FV = future value of the savings plan
- P = starting amount
- PMT = monthly contribution
- i = monthly return rate
- m = total number of months
How the savings projection works
- Begin with the initial amount as the opening balance.
- Apply the monthly growth rate to the current balance.
- Add the monthly contribution for that period.
- Store the closing balance and repeat the process for every month in the plan.
- Summarize the final value, total saved, and total growth earned.
Examples
Example 1: Monthly saving plan
Suppose you start with 25,000, add 1,000 every month, and expect 8% annual return for 10 years.
- Starting amount = 25,000
- Monthly contribution = 1,000
- Monthly rate = 8% / 12
- Duration = 120 months
- Total saved by you = 25,000 + (1,000 x 120) = 145,000
- Projected value becomes higher than 145,000 because growth is earned on both the starting amount and earlier contributions.
