💰 Annuity or Lump Sum Calculator

✅ What Is an Annuity vs. Lump Sum Decision?

When receiving a large payout — like a retirement benefit, lottery winnings, or inheritance — you typically face two options:

• Lump Sum: Receive the entire amount upfront
• Annuity: Receive fixed payments over a period of time

The Annuity vs. Lump Sum Calculator helps you compare the present value of an annuity against a lump sum offer, based on interest rates, payment duration, and your financial goals.

🔢 How the Calculator Works

For Annuity:

Present Value of Annuity=P×(1−(1+r)−n)÷r\text{Present Value of Annuity} = P \times \left(1 - (1 + r)^{-n}\right) \div rPresent Value of Annuity=P×(1−(1+r)−n)÷r

Where:

• P = periodic payment
• r = interest rate per period
• n = number of periods

For Lump Sum:

It’s simply the upfront amount offered.

The calculator compares both to tell you which option gives more value today.

🧮 Example

Option A: $50,000/year for 20 years
Option B: $700,000 lump sum today
Interest Rate (Expected Return): 5%

Using the formula, the present value of the annuity might be around $623,110.
Since $700,000 is more than $623,110 → ✅ Lump Sum is the better deal.
