David Ramsey Investment Calculator
The David Ramsey Investment Calculator is a simple yet powerful tool designed to help you project how your money can grow over time through consistent investing and compound interest.
Inspired by the financial principles of Dave Ramsey, a leading personal finance expert, this calculator focuses on disciplined, long-term investing rather than quick gains.
It’s perfect for anyone who wants to:
- Build wealth steadily
- Understand compound growth
- Plan retirement or education savings
- Visualize future returns on consistent investments
🧮 How the David Ramsey Investment Calculator Works
This calculator uses the compound interest formula to determine the future value of your investment. It takes into account:
- Your initial investment
- Your monthly contribution
- Your expected annual rate of return
- Your investment duration (in years)
- Your compounding frequency
Then it calculates how your money grows month after month — showing both your total contributions and total interest earned.
Compound Interest Formula
A=P(1+rn)nt+PMT×((1+rn)nt−1)(r/n)A = P(1 + \frac{r}{n})^{nt} + PMT \times \frac{((1 + \frac{r}{n})^{nt} – 1)}{(r/n)}A=P(1+nr)nt+PMT×(r/n)((1+nr)nt−1)
Where:
- A = Future value of investment
- P = Initial principal (starting amount)
- r = Annual interest rate (decimal)
- n = Number of compounding periods per year
- t = Time (years)
- PMT = Regular contribution

📈 Example Calculation
Scenario:
You invest $5,000 initially and add $300 per month for 20 years at a 7% annual return (compounded monthly).

- Total Contributions: $77,000

🧠 The Power of Compound Interest
Compound interest means your earnings generate more earnings. Dave Ramsey often says, “Your money works harder than you do.”
Even if you start small, time and consistency make all the difference.
For example:
- $200/month for 30 years at 8% = $271,000
- $400/month for 30 years at 8% = $542,000
- $600/month for 30 years at 8% = $813,000
That’s how consistent investing builds wealth over decades.
