Formula Used

1. Actual Day Interest

Interest = Principal × Annual Rate × (Actual Days ÷ Basis)

For ACT/365, the basis is 365. For ACT/360, the basis is 360. For ACT/ACT, each year uses 365 or 366 days.

2. Future Value

FV = P(1 + r/n)nt + PMT × [((1 + r/n)nt - 1) ÷ (r/n)]

If contributions occur at the beginning, multiply the annuity portion by (1 + r/n).

3. Present Value

PV = (Target FV - Future Value of Contributions) ÷ (1 + r/n)nt

This gives the starting amount needed today.

4. Loan Payment

PMT = PV × [i ÷ (1 - (1 + i)-N)]

Here, i is the periodic rate and N is the total number of payments.

5. Net Present Value

NPV = Σ [CFt ÷ (1 + r)t]

Positive NPV suggests value creation at the selected discount rate.

6. Internal Rate of Return

IRR is the rate where NPV = 0. This calculator estimates it numerically.

FAQs

1. What does actual-day interest mean?

It means interest uses the real number of calendar days between two dates. This often gives more precise results than assuming every month or year has a fixed length.

2. When should I use ACT/360?

ACT/360 is common in banking and some short-term money markets. It divides actual days by 360, which slightly increases quoted daily accrual compared with ACT/365.

3. What is the difference between future value and present value?

Future value projects what money can become later. Present value tells you how much you need today to reach a chosen future target.

4. Why add extra payments in the loan mode?

Extra payments reduce the remaining principal faster. That usually shortens payoff time and lowers the total interest paid across the life of the loan.

5. What does NPV tell me?

NPV shows the present worth of all future cash flows after discounting. A positive value means the project exceeds your chosen required return.

6. Why might IRR be unavailable?

IRR needs a cash-flow pattern that crosses from negative to positive meaningfully. Some unusual sequences can produce no valid solution or multiple solutions.

7. Can I use different currencies?

Yes. Enter any symbol you prefer, such as $, €, £, or Rs. The symbol changes displayed summaries without altering the underlying calculations.

8. What do the CSV and PDF buttons export?

They export the visible summary and result table. This makes it easier to save, print, review later, or share with clients and teammates.
