Savings Growth Calculator
Calculate how your savings will grow over time with compound interest and regular contributions. Plan your financial future.
Building Wealth Through Consistent Saving
Regular savings with compound interest is one of the most reliable ways to build wealth. Even modest monthly contributions can grow substantially over time. This calculator shows exactly how your savings will grow and how much interest you'll earn.
The Power of Regular Contributions
Monthly contributions are far more powerful than you might think. The combination of consistent deposits and compound interest creates exponential growth.
Example: $200/month at 4.5% for 10 years
- Total contributed: $24,000
- Interest earned: $6,180
- Final balance: $30,180
- That's 25.75% growth on your contributions!
Example: Same $200/month for 20 years
- Total contributed: $48,000
- Interest earned: $25,523
- Final balance: $73,523
- That's 53.2% growth – more than half your balance is pure interest!

Savings Strategies
1. Pay Yourself First
Automate transfers the day after payday. If you don't see it, you won't miss it. Start with 10% of income, increase to 15-20% as comfortable.
2. The 50/30/20 Rule
- 50% needs (housing, food, utilities)
- 30% wants (entertainment, dining out)
- 20% savings and debt payoff
3. Dollar-Cost Averaging
Consistent monthly contributions mean you buy more when markets are low, less when high, averaging out volatility.
4. Increase Contributions Annually
When you get a raise, increase savings by half the raise amount. You still enjoy increased income while boosting savings.

Common Savings Mistakes
- Not saving at all: Even $25/month is better than nothing
- Keeping all savings in checking: Earn 0% when you could earn 4-5%
- Using savings for non-emergencies: Breaks the habit and depletes funds
- Not increasing contributions: As income grows, savings should too
- Trying to time the market: Consistent contributions beat market timing
Emergency Fund Guidelines
Before investing, build an emergency fund covering 3-6 months of expenses:
- Single income household: 6 months minimum
- Dual income: 3 months minimum
- Self-employed: 6-12 months
- High job security: 3 months okay
- Unstable industry: 6-9 months
Tax-Advantaged Savings
Maximize these before taxable accounts:
- 401(k): $23,000 limit (2024), employer match is free money
- IRA/Roth IRA: $7,000 limit (2024), tax-free growth
- HSA: $4,150/$8,300 limit, triple tax advantage
- 529 Plan: Tax-free growth for education expenses
Maximizing Interest Earned
Chase the Best Rates
Switch to highest-rate savings accounts. Moving from 0.5% to 4.5% on $10,000 means $400/year more interest!
Maintain Minimum Balances
Some high-yield accounts require minimums for top rates. Ensure you qualify for advertised rate.
Consider CD Ladders
Instead of one 5-year CD, buy five 1-year CDs annually. Each year, reinvest matured CD into new 5-year CD. Maintains liquidity with higher rates.
Pro Tip: Set up automatic transfers from checking to savings the day after payday. Start with 10% of income. After 3 months, increase to 15%. You'll adapt to the lower spending amount and won't notice it's gone, but your savings will grow significantly!
