Plan more than your portfolio

Your finances are one lens. A confident retirement also needs clarity on health, purpose, relationships, and legacy — the same pillars we use across Retirelens.

Financial Readiness

Know where you stand and what to do next with your money.

74% of planners reported satisfaction with retirement income vs. 43% of non-planners (Goldman Sachs)

Health & Wellness

Secure solid coverage, stay ahead with preventive care and healthy habits a staple.

68% of adults ages 50–64 said they were concerned that federal policy changes could affect their health insurance coverage. (University of Michigan)

Lifestyle & Purpose

Shape days you look forward to, with steps to get there.

Research shows that a stronger sense of purpose is associated with lower mortality risk among adults over age 50. (American Medical Association)

Social Connections

Strengthen relationships and build a support circle.

A longitudinal study of adults aged 65+ found that older adults with more diverse social networks had a lower risk of death and better cognitive and physical function than those with less diverse networks. (Chico Health Aging Project)

Legacy Planning

Organize your assets and document so your family isn't left guessing.

Without a proper estate plan, more than half of families experience disputes or have assets end up under court control. (LegalShield)

How this calculator works

Each month, the balance grows at the selected annual return (compounded monthly). If contributions are at the beginning of the month, they earn a full month of interest that period; end-of-month contributions are added after growth.

The annual step-up multiplies the monthly SIP by (1 + step-up %) each year. The required SIP is solved numerically to match the future target exactly. If inflation adjustment is enabled, the target is first inflated to its future value.
