How to calculate savings

Understand how your savings grow over time using compound interest, initial deposit, and recurring contributions.

Savings Formula

A savings calculator estimates your future savings based on:

  1. Initial Deposit: The starting lump sum amount.
  2. Recurring Contributions: Monthly or yearly savings you add.
  3. Compound Interest: Interest added on both principal and prior interest.

Formula:

FV = P × (1 + r)n + PMT × [((1 + r)n - 1) / r]

Where:

  • FV = Future Value
  • P = Initial Principal
  • PMT = Recurring Contribution per Period
  • r = Interest Rate per Period
  • n = Total Number of Periods

This helps you see how much your savings could grow over time through consistent contributions and compound interest.

Plan Your Financial Growth

Understand how to maximize your savings with compound interest and smart financial planning

Saving money is one of the most important habits for financial security. Whether you're planning for retirement, a dream vacation, or your child's education, having a clear idea of how your savings will grow helps you stay on track.

Our Savings Calculator is designed to give you a simple yet powerful way to estimate the future value of your money. By entering your initial deposit, recurring contributions, time frame, and interest rate, you can instantly see how your savings may grow with the power of compound interest.

💡 What is a Savings Calculator?

A savings calculator is a tool that helps you project how much money you'll have in the future based on:

  • Initial deposit – the amount you start with.
  • Recurring contributions – money you add regularly (monthly or yearly).
  • Interest rate – how much your money earns over time.
  • Time period – how long you plan to save.

It shows you not only the final amount but also how much comes from your own contributions vs. how much comes from interest growth.

📊 How Does the Savings Calculator Work?

This calculator uses the compound interest formula:

Formula:

FV = P × (1 + r)n + PMT × [((1 + r)n - 1) / r]

Where:

  • FV = Future Value (total savings at the end)
  • P = Initial Deposit (starting amount)
  • PMT = Contribution per period (monthly or yearly)
  • r = Interest rate per period
  • n = Total number of periods

This formula ensures that interest is added not just to your principal, but also on the interest you've already earned — this is the power of compounding.

📌 Example Calculations

Let's take two examples to understand how savings grow:

Example 1: Monthly Contributions
  • Initial deposit: $1,000
  • Monthly contribution: $100
  • Interest rate: 6% annually (0.5% per month)
  • Time period: 10 years

👉 Final Savings: ~$16,400

Your total contributions = $13,000

Interest earned = ~$3,400

Example 2: Yearly Contributions
  • Initial deposit: $5,000
  • Yearly contribution: $2,000
  • Interest rate: 7% annually
  • Time period: 15 years

👉 Final Savings: ~$55,200

Your total contributions = $35,000

Interest earned = ~$20,200

🎯 Why is a Savings Calculator Useful?

  • Goal Planning – Helps you know how much to save for a target (like retirement).
  • Motivation – Seeing numbers grow encourages consistent saving.
  • Comparisons – Compare monthly vs. yearly contributions to see which works better for you.
  • Financial Discipline – Encourages long-term thinking instead of short-term spending.

🔑 Tips to Grow Your Savings Faster

  • Start Early – The earlier you start, the more compound interest works in your favor.
  • Be Consistent – Make regular contributions, even small ones.
  • Increase Contributions – Whenever your income rises, increase your savings.
  • Choose Higher Interest Accounts – Explore options like fixed deposits, SIPs, or retirement funds.
  • Avoid Withdrawals – Let your money grow undisturbed for maximum compounding.
