Present Value Calculator
Calculate how much you need to invest today to reach your future financial goal
Present Value Calculator
Present Value Calculator helps you answer one of the most important financial questions: “How much is my future money worth today?” Whether you’re planning investments, retirement, or valuing annuities, present value (PV) is the key to making smart financial decisions.
With this tool, you can quickly determine how much you’d need to invest right now to reach a specific future value (FV), given an interest rate, time period, and compounding frequency.
What Is Present Value (PV)?
Present Value is the current worth of a sum of money that you will receive (or pay) in the future, discounted back at a given rate of return.
In simple words: money today is worth more than money tomorrow because it can be invested and grow.
Example:
- If you want $10,000 five years from now, at a 5% annual interest rate, the present value will be less than $10,000.
- The PV tells you exactly how much you need to set aside today.
This idea comes from the time value of money (TVM) principle, which underpins all modern finance.
Present Value Formula
The general formula for calculating present value is:
PV = FV / (1 + i)^n
Where:
- PV = Present Value
- FV = Future Value
- i = Interest rate per period
- n = Number of periods
This formula discounts future money into today’s terms.
How the Present Value Calculator Works
Our Present Value Calculator makes PV calculations easy. You simply enter:
- Future Value (FV): The amount of money in the future.
- Time (n): Number of periods (years, months, etc.).
- Interest Rate (R): Discount or return rate per period.
- Compounding Frequency (m): Annual, quarterly, monthly, daily, or continuous.
- Cash Flow Payments (PMT): Regular outflows if applicable.
- Growth Rate (g): If annuities grow over time.
- Payment Timing (T): Payments at the beginning or end of a period.
The calculator instantly gives you the Present Value (PV) result, whether you’re valuing a lump sum, annuity, perpetuity, or growing cash flow.
Why Present Value Matters
Understanding PV helps you:
- Plan investments – know how much to invest now for future goals.
- Evaluate loans & mortgages – compare repayment structures.
- Retirement planning – determine today’s savings needed for a target future fund.
- Business decisions – calculate the worth of projects or contracts.
- Compare alternatives – decide between receiving money today vs. in the future.
Simply put: PV helps you make smarter money choices.
Present Value of a Future Sum
The simplest application is discounting a single lump sum:
PV = FV / (1 + i)^n
Example:
- You expect $5,000 in 3 years.
- The discount rate is 6% annually.
- PV = 5000 / (1 + 0.06)^3 = $4,198.60
So, $5,000 in three years is worth about $4,199 today.
Present Value of an Annuity
An annuity is a series of equal payments over time. The formula for the PV of an ordinary annuity (payments at the end of each period) is:
PV = PMT × [1 – (1 + i)^-n] / i
- Ordinary Annuity (T=0): Payments at the end of each period.
- Annuity Due (T=1): Payments at the beginning of each period (worth slightly more).
This is useful for valuing pensions, mortgages, or structured payments.

Present Value of a Growing Annuity
When payments grow at a constant rate g:
PV = PMT × [1 – ((1+g)/(1+i))^n] / (i – g) × (1 + iT)
This applies to situations like dividend payments increasing annually.
Present Value of a Perpetuity
A perpetuity is an infinite series of equal payments (like a trust fund payout). The formula is simple:
PV = PMT / i
If payments grow at rate g, the formula becomes:
PV = PMT / (i – g) (valid if i > g).
Continuous Compounding and Present Value
When interest compounds continuously, the formula adjusts to:
PV = FV × e^(-rt)
Where:
- e = Euler’s constant (~2.718)
- r = interest rate
- t = time
This is used in advanced finance and options pricing.

Present Value in Practice: Examples
| Scenario | Future Value | Rate | Time | PV Today |
|---|---|---|---|---|
| Lump Sum | $10,000 | 5% | 10 years | $6,139 |
| Annuity | $500 yearly | 6% | 8 years | $3,107 |
| Growing Annuity (g=3%) | $1,000 yearly | 7% | 15 years | $9,578 |
| Perpetuity | $2,000 yearly | 5% | Forever | $40,000 |
