How to Use the Savings Calculator

  1. 1. Enter your starting balance - input the amount you currently have saved (enter $0 if starting fresh).
  2. 2. Set your monthly deposit - enter the amount you plan to save each month.
  3. 3. Enter the interest rate (APY) - input the annual percentage yield from your savings account (check your bank's current rate).
  4. 4. Choose your time horizon - set the number of years you plan to save toward your goal.
  5. 5. Review your breakdown - see your total savings, interest earned, and deposits side by side. Try adjusting the monthly deposit or APY to see how small changes compound over time.

Savings Calculator

This calculator shows how your savings will grow over time with a starting balance, regular monthly deposits, and compound interest. It breaks down your total into deposits versus interest earned so you can see exactly how much of your future balance comes from your own contributions and how much is free growth from compounding.

How Savings Growth Is Calculated

The calculator uses the compound interest formula with monthly compounding:

  • Future Value = Starting Balance x (1 + r/12)^(12t) + Monthly Deposit x [((1 + r/12)^(12t) - 1) / (r/12)]
  • Where r = annual interest rate and t = number of years
  • Total Deposits = Starting Balance + (Monthly Deposit x 12 x Years)
  • Interest Earned = Future Value - Total Deposits

$1,000$2004.0%5~$14,300~$1,300

Key Factors That Affect Savings Growth

  • Monthly deposit consistency — automating deposits removes the temptation to skip months
  • Interest rate (APY) — high-yield savings accounts currently offer 4-5%, compared to 0.01-0.5% at traditional banks
  • Compounding frequency — monthly compounding (used here) earns slightly more than annual compounding
  • Time horizon — the longer you save, the greater the proportion of your balance that comes from interest rather than deposits
  • Inflation — a 4.5% return with 3% inflation yields only about 1.5% in real purchasing power growth

Tips

  1. Open a high-yield savings account to earn 4-5% APY instead of the 0.01% offered by many traditional banks
  2. Set up automatic monthly transfers on payday so deposits happen before you have a chance to spend
  3. Even a small increase in monthly deposits ($50 more per month) compounds into thousands over a decade
  4. Use this calculator to set a concrete savings goal, then track your progress quarterly

Frequently Asked Questions

What is a high-yield savings account and how much more can I earn?
A high-yield savings account (HYSA) is an FDIC-insured savings account that pays significantly more interest than a traditional bank account. As of 2025, top HYSAs offer 4.0-5.0% APY, while the national average for traditional savings accounts is just 0.01-0.5%. On a $10,000 balance, a 4.5% HYSA earns roughly $450 per year compared to just $1-$50 at a traditional bank. Online banks typically offer the highest rates because they have lower overhead costs.
How much of my income should I be saving each month?
A widely recommended guideline is the 50/30/20 rule: 50% of after-tax income for needs, 30% for wants, and 20% for savings and debt repayment. If you earn $5,000 per month after taxes, that means $1,000 toward savings. However, the right amount depends on your goals. If you are building an emergency fund, prioritize saving 3-6 months of expenses as quickly as possible. If you are saving for retirement, aim to contribute 15% of gross income across all retirement accounts.
How large should my emergency fund be?
Most financial advisors recommend saving 3-6 months of essential living expenses in an easily accessible account. If your monthly essentials (rent, food, insurance, utilities, minimum debt payments) total $3,000, aim for $9,000-$18,000. Freelancers, self-employed workers, or those with variable income should target 6-12 months. Keep emergency funds in a high-yield savings account where they earn interest while remaining instantly accessible -- not locked in CDs or invested in the stock market.
At what point should I invest instead of keeping money in savings?
Keep your emergency fund and any money you need within 1-3 years in a savings account for safety and liquidity. Beyond that, investing typically makes more sense for long-term goals. Savings accounts earning 4-5% APY barely keep pace with inflation (around 3%), meaning your real growth is only 1-2%. The stock market has historically returned 7-10% annually, providing significantly more real growth over 5+ year horizons. The trade-off is volatility -- investments can lose value in the short term.
How does inflation erode my savings over time?
Inflation reduces the purchasing power of your money each year. At 3% annual inflation, $100 today will only buy about $74 worth of goods in 10 years and $48 worth in 25 years. If your savings account earns 4.5% and inflation is 3%, your real return is only about 1.5%. This means a $50,000 balance grows to roughly $58,000 in real purchasing power after 10 years rather than the $77,000 nominal value. For long-term goals, it is critical to account for inflation when setting your savings target.
