What is a reverse CAGR calculator?

A reverse CAGR calculator projects future investment value using a known compound annual growth rate. While a regular CAGR calculator determines your historical growth rate from past performance, a reverse CAGR calculator uses an expected growth rate to forecast what your investment will be worth in the future.

How do you calculate future value with CAGR?

Future Value = Present Value × (1 + CAGR)^Years. For example, if you have $10,000 and expect 10% annual growth for 10 years: $10,000 × (1.10)^10 = $25,937. This formula assumes compound growth where gains are reinvested each year.

What is a realistic CAGR for long-term stock investments?

Historically, the S&P 500 has delivered approximately 10% CAGR over long periods (before inflation). More conservative estimates use 7% (inflation-adjusted). Growth stocks may achieve 12-15%+, while bonds typically return 4-6%. Always use realistic assumptions for financial planning.

How can I use reverse CAGR for retirement planning?

Enter your current retirement savings as the starting value, use a conservative expected return (6-8% for diversified portfolios), and set the years until retirement. The calculator shows your projected nest egg. Compare multiple scenarios with different contribution levels or growth rates to see how changes affect your outcome.

What is the reverse CAGR formula in Excel?

In Excel, use: =A1*(1+B1)^C1 where A1 is your starting value, B1 is the CAGR as a decimal (e.g., 0.10 for 10%), and C1 is the number of years. For example, =10000*(1+0.10)^10 returns $25,937.42.

What is the difference between CAGR and reverse CAGR?

CAGR calculates the growth rate from known start and end values (answering 'What was my return?'). Reverse CAGR calculates the future value from a known growth rate (answering 'What will my investment be worth?'). They use the same compound growth math but solve for different variables.

Can I use reverse CAGR for Bitcoin and cryptocurrency?

Yes, reverse CAGR works for any asset class including Bitcoin and cryptocurrencies. However, crypto is highly volatile, so projections are less reliable than for diversified stock portfolios. Use conservative estimates and understand that actual results may vary significantly from projections.

Why compare multiple CAGR scenarios?

Comparing scenarios helps you understand the range of possible outcomes. Markets don't deliver consistent returns—some years are better, some worse. By modeling conservative, moderate, and optimistic scenarios, you can plan for different outcomes and make more informed investment decisions.

What are the limitations of reverse CAGR projections?

Reverse CAGR assumes constant annual growth, which never happens in reality. Markets are volatile, and past performance doesn't guarantee future results. Projections don't account for fees, taxes, inflation, or behavioral factors like panic selling. Use projections as rough guides, not guarantees.

How does compounding affect investment growth?

Compounding creates exponential growth because you earn returns on your returns. At 10% CAGR, $10,000 becomes $25,937 after 10 years and $67,275 after 20 years. The longer your time horizon, the more powerful compounding becomes—which is why starting early matters so much for retirement savings.

What is Reverse CAGR?

Reverse CAGR (also called a future value calculator) projects what your investment will be worth based on an expected compound annual growth rate. While a standard CAGR calculator answers "What was my return?", a reverse CAGR calculator answers "What will my investment be worth?"

This is essential for financial planning, retirement projections, and goal-setting. By modeling different growth scenarios, you can understand the range of possible outcomes and make informed decisions about your investment strategy.

Reverse CAGR Formula (Future Value)

The future value formula using CAGR is:

Future Value = Present Value × (1 + CAGR)^Years

Where:

Present Value = Your initial investment amount
CAGR = Expected compound annual growth rate (as decimal, e.g., 0.10 for 10%)
Years = Investment time horizon

Example: Projecting Retirement Savings

Scenario: You have $50,000 in your retirement account and expect 8% average annual returns for the next 25 years.

Future Value = $50,000 × (1 + 0.08)^25
Future Value = $50,000 × 6.8485
Future Value = $342,424

Result: Your $50,000 could grow to approximately $342,424 over 25 years at 8% CAGR.

Reverse CAGR Formula in Excel

To calculate future value in Microsoft Excel or Google Sheets:

=PresentValue*(1+CAGR)^Years

Example with cell references:

	A	B	C	D
1	Present Value	CAGR	Years	Future Value
2	$10,000	10%	10	`=A2*(1+B2)^C2`

Alternatively, use Excel's FV function: =FV(B2, C2, 0, -A2) for the same result.

Common CAGR Benchmarks for Projections

When projecting future value, use realistic growth rate assumptions based on historical data:

Investment Type	Typical CAGR Range	Best For
High-yield Savings	3-5%	Emergency funds, short-term goals
Bonds (Investment Grade)	4-6%	Conservative investors, near retirement
Balanced Portfolio (60/40)	6-8%	Moderate risk tolerance
S&P 500 Index	8-10%	Long-term stock investors
Growth Stocks	10-15%+	Aggressive investors, long horizon
Cryptocurrency	Highly variable	Speculative, high-risk allocation

These are historical ranges, not guarantees. Always use conservative estimates for financial planning.

Limitations of Growth Projections

Assumes Constant Growth

Real markets don't deliver steady returns. Annual returns vary wildly—the S&P 500 might return 30% one year and -10% the next, even if the long-term CAGR is 10%.

Ignores Fees & Taxes

Projections don't account for investment fees, management costs, or taxes on gains. These can significantly reduce your actual returns over time.

Past ≠ Future

Historical returns don't guarantee future performance. Economic conditions, market cycles, and unforeseen events can dramatically affect actual results.

Inflation Impact

Nominal returns don't account for inflation. $100,000 in 20 years will have less purchasing power than today. Consider using inflation-adjusted returns (real returns).

Frequently Asked Questions

A reverse CAGR calculator projects future investment value using an expected compound annual growth rate. While regular CAGR calculates your historical return from past performance, reverse CAGR uses an expected growth rate to forecast what your investment will be worth.

Use the formula: Future Value = Present Value × (1 + CAGR)^Years. For example, $10,000 at 10% for 10 years: $10,000 × (1.10)^10 = $25,937. Our calculator does this automatically and lets you compare multiple scenarios.

For long-term stock investments, 7-10% is commonly used (S&P 500 historical average). Use 5-7% for conservative planning, 4-6% for bonds. Always run multiple scenarios to see a range of outcomes rather than relying on a single projection.

Yes, the formula works for any asset. However, cryptocurrency is extremely volatile with no reliable historical average. Use very wide scenario ranges and understand that crypto projections are highly speculative compared to diversified stock portfolios.

Enter your current savings, a conservative expected return (6-8% for diversified portfolios), and years until retirement. Compare scenarios to see how different growth rates affect your outcome. Use the conservative scenario for planning to avoid disappointment.

Markets are unpredictable. Comparing conservative (5-7%), moderate (8-10%), and optimistic (12%+) scenarios shows the range of possible outcomes. This helps you plan for different situations rather than betting everything on one projection.

In Excel: =PresentValue*(1+CAGR)^Years. With cells: =A2*(1+B2)^C2 where A2 is starting value, B2 is CAGR as decimal (0.10 for 10%), C2 is years. Or use Excel's built-in: =FV(rate, periods, 0, -present_value).

CAGR finds your growth rate from known start/end values ("What was my return?"). Reverse CAGR finds future value from a known growth rate ("What will I have?"). Same math, different unknown variable. Use our CAGR Calculator for the former.

No, this calculator assumes a single lump sum investment. For projections with regular contributions (like monthly 401k deposits), you need a future value of annuity calculator or use Excel's FV function with a payment parameter.

Compounding creates exponential growth. At 10% CAGR, $10,000 becomes $25,937 after 10 years, $67,275 after 20 years, and $174,494 after 30 years. Small differences in CAGR have huge impacts over long periods—which is why comparing scenarios matters.

Disclaimer: This calculator is for educational and illustrative purposes only. Projections assume constant returns, which never happens in real markets. Past performance does not guarantee future results. Actual returns will vary. Consult a qualified financial advisor for personalized investment advice.
