Multi-Mode Compound Interest Calculator
- Compound Interest: FV = P × (1 + r/n)nt + PMT × [((1 + r/n)nt – 1) / (r/n)] – W × [((1 + r/n)nt – 1) / (r/n)]
- Simple Interest: FV = P + (P × r × t) + (PMT – W) × t
- Forex Compound: Similar to compound interest; assumes currency fluctuations simulated by a multiplier (default 1.1)
P = Principal, r = annual rate decimal, n = compounding periods/year, t = years, PMT = recurring deposit per period, W = recurring withdrawal per period
- Principal: Your starting amount.
- Recurring Deposit/Withdraw: Amount added/withdrawn each deposit/withdraw period.
- Interest Rate Type: Period to which interest rate applies.
- Forex Compound: Simulates compound interest with currency multiplier effect.

What is Compound Interest?
Compound interest is like a magic multiplier for your money. Unlike simple interest, which is calculated only on the initial principal amount, compound interest considers both the principal and the accumulated interest, resulting in exponential growth over time. Essentially, you earn interest not only on your original investment but also on the interest that accumulates over time.
What is the Formula for compound interest?
The formula for compound interest allows you to calculate the future value of an investment, considering both the initial principal amount and the interest earned over time. Here’s the breakdown:
A = P (1 + r/n) ^ (nt)
Where:
- A represents the future value (total amount) after considering compound interest.
- P represents the principal amount (initial investment).
- r represents the annual interest rate (as a decimal, not a percentage). To convert a percentage rate to a decimal, divide by 100 (e.g., 5% = 0.05).
- n represents the number of times the interest is compounded in a year. For example, if interest is compounded monthly (12 times a year), n would be 12.
- t represents the investment period (in years).
Here’s an example to illustrate:
Imagine you invest $1,000 (P) at an annual interest rate of 5% (r). You plan to keep the investment for 2 years (t), and the interest compounds annually (n = 1).
A = $1,000 (1 + 0.05 / 1) ^ (1 * 2)
A = $1,000 (1.05) ^ 2
A = $1,000 x 1.1025
A ≈ $1,102.50
Following this formula, you can see that after two years with an annual compounding rate, your investment would grow to approximately $1,102.50.
How Does Compound Interest Work?
Let’s break it down. Say you invest $1,000 in an account with a 5% annual interest rate compounded annually. At the end of the first year, you’ll earn $50 in interest, bringing your total to $1,050. In the second year, you’ll earn 5% interest not just on your initial $1,000, but on the entire $1,050, resulting in $52.50 in interest. This cycle continues, with your money snowballing over time.
