💰 Lump Sum vs Annuity Calculator – Compare the Better Payout Option Instantly
A Lump Sum vs Annuity Calculator helps individuals make informed decisions when choosing between a one-time payout or regular income payments over time. It’s often used in situations like retirement plans, lottery winnings, settlements, and pensions.
🧾 What Is the Difference?
| Feature | Lump Sum | Annuity |
|---|---|---|
| Definition | One-time payment | Series of payments over a fixed period |
| Flexibility | High – invest or spend anytime | Fixed – predictable income |
| Tax Impact | Often taxed upfront | May be taxed as you receive payments |
| Risk | Market risk (if reinvested) | Lower, more stable |
| Control | You manage funds | Provider controls the payouts |
🔢 How the Calculator Works
The calculator compares the present value of both options by discounting future annuity payments to today’s value.
🧮 Formula Used
🔹 Present Value of Annuity:
PVA=PMT⋅(1−(1+r)−nr)PVA = PMT \cdot \left( \frac{1 – (1 + r)^{-n}}{r} \right)PVA=PMT⋅(r1−(1+r)−n)
Where:
- PMTPMTPMT = periodic annuity payment
- rrr = interest rate per period
- nnn = total number of payments
You then compare this value to the lump sum offered.
🧠 Example
- Lump Sum: ₹25,00,000
- Annuity: ₹2,50,000 per year for 12 years
- Discount rate: 6%
PVA=2,50,000⋅(1−(1+0.06)−120.06)≈₹21,45,000PVA = 2,50,000 \cdot \left( \frac{1 – (1 + 0.06)^{-12}}{0.06} \right) ≈ ₹21,45,000PVA=2,50,000⋅(0.061−(1+0.06)−12)≈₹21,45,000
👉 Better Option: Lump Sum (₹25,00,000 > ₹21,45,000)

❓ FAQs – Lump Sum vs Annuity Calculator
🔹 When is lump sum better?
When you expect to earn a better return on investment than the annuity’s implied rate or if you prefer flexibility.
🔹 When is annuity better?
If you want guaranteed income, less responsibility, or tax deferral benefits.
🔹 Does inflation impact the decision?
Yes. An annuity with no inflation adjustment will lose value in real terms over time.
🔹 What interest rate should I use?
Use your expected return on investment, or consult with a financial advisor for a discount rate.
🔹 Can I include taxes?
Some advanced calculators include after-tax comparisons. Basic ones often do pre-tax.
🔹 What if the annuity is for life?
Use life expectancy estimates or actuarial tables to estimate the number of periods.
