What is compound interest calculator moneychimp?

Compound Interest Calculator Moneychimp Formula and Mathematical Explanation
The compound interest calculator moneychimp relies on the future value of a lump sum plus a series of equal contributions. The core expression used by the compound interest calculator moneychimp is FV = P(1+r/n)^(nt) + PMT * [((1+r/n)^(nt)-1)/(r/n)] with an adjustment for beginning-of-period contributions. In the compound interest calculator moneychimp, P is the initial principal, r is the nominal annual rate, n is compounding periods per year, t is years, and PMT is the periodic contribution. If contributions occur at the beginning of each period, the compound interest calculator moneychimp multiplies the contribution term by (1+r/n) to reflect the extra compounding.
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| P | Initial principal used by the compound interest calculator moneychimp | Dollars | $100 – $1,000,000 |
| r | Nominal annual rate in the compound interest calculator moneychimp | Decimal | 0.01 – 0.20 |
| n | Compounds per year for the compound interest calculator moneychimp | Periods/year | 1 – 365 |
| t | Years in the compound interest calculator moneychimp | Years | 1 – 60 |
| PMT | Contribution per period in the compound interest calculator moneychimp | Dollars | $0 – $50,000 |
