What is the FD Laddering?
FD laddering splits one lump sum across several deposits maturing in successive years. Instead of locking ₹10 lakh for five years at one rate, you place ₹2 lakh each in 1, 2, 3, 4 and 5-year deposits.
The result is an FD maturing every year — giving you liquidity without breaking deposits, and letting you reinvest at whatever rates prevail rather than betting everything on today's.
Formula & worked example
Each rung: Maturity = P × (1 + r/4)4n
Worked example: ₹10,00,000 across five rungs means ₹2,00,000 each in 1 to 5-year FDs. One matures every year, which you can either spend or roll into a new 5-year deposit — after year five you hold a permanent ladder with annual liquidity.
How to use this fd laddering calculator
- Enter the total amount you want to deposit.
- Choose the number of rungs — 5 is the most common.
- Use an average rate; longer tenures typically carry slightly higher rates.
- As each rung matures, reinvest it at the longest tenure to maintain the ladder.
Smart tips
- Laddering removes the need to guess where rates are going — you average across the cycle.
- It also avoids premature-withdrawal penalties, since something matures every year.
- Keep each rung under ₹5 lakh per bank to stay within DICGC deposit insurance limits.
- In a falling-rate environment, weight the ladder towards longer tenures to lock current rates.
- Combine with a sweep-in account so idle maturity proceeds still earn until reinvested.
Frequently asked questions
What is FD laddering?
Splitting a lump sum across FDs of different maturities so one matures every year, giving regular liquidity and averaging out interest rate risk.
Is laddering better than one long FD?
It usually yields slightly less than locking everything at the longest rate, but provides annual liquidity and protects against rate changes.
How many rungs should I use?
Five is standard. More rungs mean smaller deposits and more paperwork; fewer reduce the liquidity benefit.
What happens when a rung matures?
Reinvest it in a new deposit at the longest tenure in your ladder, so the structure keeps rolling with annual maturities.
