How does a savings planner calculator work?
A savings planner calculator uses compound interest math to project how your money grows over time. It adds your monthly contribution, applies your interest rate each month, and repeats for the number of months in your time horizon. The result shows your final balance and how much of it came from interest.
How much should I save each month?
A common guideline is 20% of take-home pay — the 50/30/20 rule. On $5,000 monthly take-home that means $1,000 per month. Use the savings planner calculator to see what your current savings rate builds over 10, 20, and 30 years. Then check our FIRE calculator to see when you could retire early.
What interest rate should I use in the savings planner?
For a high-yield savings account, use 4–5%. For a balanced investment portfolio, 6–8% is a reasonable long-term assumption. The S&P 500 has averaged around 10% annually over 30 years, but past performance does not guarantee future results.
How much do I need to save to reach $100,000?
At $500/month with a 5% return, you reach $100,000 in about 13 years. At $1,000/month, you get there in about 7 years. Adjust all variables above to find your exact timeline.
