Final Amount = Principal × (1 + Rate)^Years + Monthly × [((1 + Rate)^Years - 1) / Rate]

💡How it works

Compound interest grows your money exponentially. Your principal earns interest, and that interest earns interest too, creating a snowball effect over time.

ℹ️ What is Savings Calculator?

A savings calculator projects how your money grows over time with regular contributions and compound interest. It helps you set realistic savings goals, understand the power of compound growth, and determine how much you need to save each month to reach a target amount.

📐 Formula

FV = PV × (1+r)ⁿ + PMT × [(1+r)ⁿ−1] / r
FV— Future value — total savings at end of period
PV— Present value — current savings balance
PMT— Regular monthly contribution
r— Monthly interest rate (annual rate / 12 / 100)
n— Number of months

✏️ Worked Example

Starting Balance: $1,000
Monthly Deposit: $200
Annual Rate: 5%
Duration: 10 years
  1. 1Monthly rate r = 5 / 12 / 100 = 0.004167
  2. 2n = 120 months
  3. 3Growth of initial $1,000: $1,000 × (1.004167)¹²⁰ = $1,647
  4. 4Growth of monthly deposits: $200 × [(1.004167)¹²⁰ − 1] / 0.004167 = $31,056
  5. 5Total FV = $1,647 + $31,056 = $32,703
  6. 6Total deposited = $1,000 + ($200 × 120) = $25,000
  7. 7Total interest earned = $32,703 − $25,000 = $7,703
✅ Result: Final Balance = $32,703 | Interest Earned = $7,703

💡 How to Interpret Results

  • ▸The earlier you start, the more compound interest works in your favor — even small amounts grow significantly over decades.
  • ▸Doubling your monthly contribution has a larger effect than doubling the interest rate.
  • ▸High-yield savings accounts (HYSA) typically offer 4–5% APY — much better than traditional 0.01% accounts.
  • ▸Subtract expected inflation (around 3%) from the interest rate to get your "real" return.
  • ▸Tax-advantaged accounts (401k, IRA, PPF) let your savings compound without annual tax drag.
