Understanding Compound Interest
Compound interest is the foundation of wealth building and one of the most powerful financial concepts. It's the interest you earn on both your original principal and previously earned interest.
How Compound Interest Works
When you save money in an account that earns compound interest, your money grows exponentially over time. Each period, you earn interest not just on your original deposit but also on all the interest you've accumulated.
Formula Used
Our savings calculator uses the compound interest formula with regular contributions:
A = P(1 + r/n)^(nt) + PMT × [((1 + r/n)^(nt) - 1) / (r/n)]
Where:
- A = Final amount
- P = Principal (initial deposit)
- r = Annual interest rate (as decimal)
- n = Number of times interest compounds per year
- t = Time in years
- PMT = Regular payment amount
Calculation Steps
Our savings calculator performs the following calculations:
- Convert annual rate to periodic rate: Divide annual rate by compounding frequency
- Calculate compound periods: Multiply years by compounding frequency
- Calculate future value of initial deposit: Apply compound interest formula to principal
- Calculate future value of monthly contributions: Use annuity formula for regular payments
- Sum total final amount: Add future values of principal and contributions
- Calculate interest earned: Subtract total contributions from final amount
- Calculate return on investment: Express interest earned as percentage of contributions

Frequently Asked Questions
How does compound interest work in savings?
Compound interest is interest calculated on both the initial principal and the accumulated interest from previous periods. This means your money grows exponentially over time as you earn interest on your interest.
What's the difference between simple and compound interest?
Simple interest is calculated only on the principal amount, while compound interest is calculated on the principal plus any previously earned interest. Compound interest grows your savings faster over time.
How often should I contribute to my savings?
Regular monthly contributions are ideal for building savings habits and maximizing compound interest benefits. Even small, consistent contributions can grow significantly over time.
What's a good interest rate for savings?
Interest rates vary by institution and economic conditions. High-yield savings accounts typically offer 0.5-5% annually, while investment accounts may offer higher returns with increased risk.
Should I choose daily or monthly compounding?
More frequent compounding (daily vs. monthly) results in slightly higher returns. However, the difference is minimal for most savings accounts. Monthly compounding is most common.
How accurate is this calculator?
Our calculator provides accurate mathematical projections based on your inputs. However, actual returns may vary due to market conditions, fees, and changes in interest rates.
