Frequently Asked Questions
How does compound interest affect my savings goal?
Compound interest earns returns on both your contributions and previously earned interest. Over long periods, this creates exponential growth — the difference between earning 5% vs. 0% on a $50,000 goal over 10 years is tens of thousands of dollars in required contributions. The earlier you start, the more compounding works in your favor.
What interest rate should I use for my savings goal?
It depends on where you're saving. High-yield savings accounts currently pay 4–5% APY. CDs can range 4–5.5%. A diversified investment portfolio historically averages 7–10% annually but carries risk. For short-term goals (under 3 years), use 4–5%. For long-term goals, 6–8% is a reasonable conservative estimate.
Should I include my current savings in this calculation?
Yes — your starting balance compounds just like contributions do. If you already have $5,000 saved toward a $20,000 goal, that initial amount earns interest and significantly reduces how much you need to contribute monthly. Enter your current savings in the 'Current Savings' field.
What's a realistic monthly savings rate?
Financial experts typically recommend saving 20% of your take-home pay (the 50/30/20 rule). For specific goals, work backwards from your deadline and target amount. If the required monthly contribution exceeds 20–25% of your income, consider extending your timeline or increasing your target rate of return.
How is the required monthly contribution calculated?
The calculation uses the future value of an annuity formula. Given your target amount, current savings, interest rate, and deadline, it solves for the periodic payment needed for your balance to reach the goal on time. The formula accounts for compounding interest on both existing savings and new contributions.
What's the difference between APY and APR?
APY (Annual Percentage Yield) accounts for compounding within the year — it's what you actually earn. APR (Annual Percentage Rate) does not include compounding. For savings accounts and this calculator, always use the APY figure from your bank, which is what you see advertised on high-yield savings accounts.
