Comprehensive retirement planning engine. Projects required post-retirement corpus based on living expenses, pre and post-retirement inflation rates, required monthly investment SIPs, and 4% rule FIRE numbers.
Runs entirely in your browser
Planning for retirement means answering two questions: how large a corpus you will need to fund your expenses after you stop working, and how much you must invest each month to get there. This planner estimates both, projecting your target corpus from your expected living expenses and inflation (before and after retirement), and calculating the monthly SIP required to reach it — along with your 4% rule FIRE number.
Inflation is the factor most back-of-envelope plans miss: expenses that seem manageable today grow substantially over decades, so the corpus needed is larger than intuition suggests. Modelling pre- and post-retirement inflation separately gives a more realistic target than a single flat assumption.
It runs in your browser, so your figures stay private. All projections rest on assumptions about returns and inflation that will not hold exactly, so use it to set a direction and revisit it periodically rather than as a fixed guarantee.
