Financial Calculator: Plan Your Loans, Investments & Retirement

Q: What is the formula for a loan payment?

The formula used is the standard amortization formula: P = [PV * r * (1+r)^n] / [(1+r)^n - 1], where P is the monthly payment, PV is the loan amount, r is the monthly interest rate, and n is the total number of payments. Our calculator does the math for you instantly.

Frequently Asked Questions

What is Compounding Interest?

Compounding interest is the interest earned on both the initial principal and the accumulated interest from previous periods. In other words, it's "interest on interest," and it's what makes investments grow exponentially over time. The more frequently interest is compounded, the faster your investment will grow.

How does inflation affect my savings?

Inflation is the rate at which the general level of prices for goods and services is rising, and subsequently, purchasing power is falling. If your savings are growing at a 5% annual rate but inflation is at 3%, the "real" return on your money is only 2%. Our calculator's inflation adjustment feature discounts your future savings back to today's dollars, giving you a clear picture of its actual purchasing power.

What is the formula for a loan payment?

The formula used is the standard amortization formula: $P = \frac{PV \cdot r \cdot (1+r)^n}{(1+r)^n - 1}$, where P is the monthly payment, PV is the loan amount, r is the monthly interest rate, and n is the total number of payments. Our calculator does the math for you instantly.

How can I see my investment grow over time?

After you enter your initial investment, monthly contribution, interest rate, and term in the "Investment" tab, our calculator generates a line chart. This chart visually displays your total contributions versus the total growth, clearly showing how compound interest accelerates your wealth over the years.

Is my retirement goal realistic?

The "Retirement" calculator helps you answer this. By inputting your goal, current savings, and expected interest rate, it calculates the required monthly savings. If the number seems too high, you can adjust your timeline or retirement goal to find a more achievable plan.
