Ages
Household retirement starts when the later of you reaches this age.
Plan each of you to
The household must fund expenses until whichever of these is later.
Household spending
Rent, utilities and much of the fixed budget continue — this rarely falls anywhere near 50%.
Your plan
Corpus required for the full household plan

27 years with both of you drawing the full household expense, then 8 more years for the survivor at a reduced expense — 35 years in total from retirement.
Your corpus at retirement

The single-life understatement
A plan built to only the earlier of your two planning ages — as if the household stopped needing income at the first death — would look sufficient at a meaningfully smaller corpus. That gap is the risk of planning for one life when you actually need to fund two.
If planned to the first death only
₹1.98 Cr

₹31.9 L
Corpus over the two phases
The marker shows where the plan assumes the first death and expenses step down by 25%. Everything after that funds the survivor alone, at ₹0/mo to start.

Every retirement calculator on the Indian internet models one person
Almost without exception, retirement calculators project a single life expectancy and stop there. For a household of two, that is the wrong end date — see our longevity risk guide for why planning to any single life expectancy, individual or joint, understates what the tail of the distribution actually requires.
Two phases, not one
This calculator splits the household's remaining years into two distinct phases: the years both of you are alive, funded at the full household expense, and the years after the earlier of your two planning ages, funded at a reduced — but very much ongoing — expense for the survivor alone. The corpus required is solved across both phases together, using the same month-by-month simulation as our SWP calculator.

Frequently asked questions
Why does a couple need a different calculation than an individual?
Because the household corpus has to fund expenses until the LATER of two deaths, not the first. A calculator built for one person understates what a household actually needs, sometimes by a wide margin, because it implicitly stops the clock too early.
Why not just assume expenses halve when one partner dies?
Because they rarely do. Rent or home-loan EMI, utilities, property tax, insurance premiums and much of the fixed household budget continue largely unchanged regardless of headcount. This calculator lets you set a more realistic reduction — commonly 20-30% rather than 50%.
How do I choose the planning ages?
The same logic applies as for an individual: planning to average life expectancy is close to a coin flip on the most important input in the whole calculation. Many planners use 90-95 for each partner rather than a population average, because running out of money late in life is a far worse outcome than leaving some behind.
What does the "single-life understatement" figure show?
It shows what your corpus target would look like if the plan (incorrectly) assumed the household stopped needing income at the first, earlier death. The gap between that number and the real joint-planning figure is the risk of using an individual retirement calculator for a two-person household.
