Methodology & Assumptions
How this estimate is calculated
Formula: Future Value = P(1+r)^n + PMT×[((1+r)^n−1)/r]. Contributions are added at the end of each month and compounding is monthly. The return input is nominal; taxes, fees, and inflation are not deducted.
Illustrative result: figures are rounded for display after calculations use full numeric precision. Actual results may differ.
Currency: dollar symbols are a display convention. Enter every monetary amount in one consistent currency; the calculator does not convert currencies or apply jurisdiction-specific tax rules.
How to Use This Savings Goal Calculator

| $1,000,000 portfolio | $2,500 | 7% | ~17.5 years |
The Three Variables That Control Your Timeline
Monthly contribution is the most controllable variable. Increasing contributions by $200/month can cut years off your timeline. Automate transfers on payday — you cannot spend money that never reaches your checking account.
Starting amount has an outsized early impact. A $5,000 head start at 7% grows to $38,000 in 30 years without any additional contributions — valuable momentum at the beginning of any goal.
Return rate matters more over longer time horizons. For goals under 3 years, use a high-yield savings account (4-5%) rather than investments. For goals 5+ years away, equities at 6-8% dramatically accelerate results.

Frequently Asked Questions
Should I invest my savings goal money in stocks?
Only if the timeline is 5+ years and you can tolerate volatility. For short-term goals (under 3 years), a high-yield savings account at 4-5% is appropriate — stocks can drop 30-40% right when you need the money. Match the investment vehicle to your timeline.
What return rate should I use for investment goals?
Use a rate consistent with the asset mix, whether the input is nominal or real, and your planning horizon. Current cash rates and expected investment returns change over time; test a conservative range instead of relying on one forecast.
How does inflation affect my savings goal?
For long-term goals (10+ years), your target amount should account for inflation. A $100,000 goal today requires saving for $134,000 in 10 years at 3% inflation to maintain the same purchasing power. Use our inflation calculator to adjust your target.
What's the fastest way to reach $100,000?
At $2,000/month invested at 7%, you reach $100,000 in approximately 3.7 years. At $1,000/month, it takes about 6.5 years. The fastest path combines maximizing monthly contributions with employer 401k matching (an instant 50-100% return on the matched portion).
