Overview

Retirement Planning Calculator estimates the total retirement fund needed, suggested monthly savings, and funding gap. It supports inflation, salary growth, retirement income growth, and post-retirement return assumptions for long-term budget planning.

Key Features

  • Estimate retirement target fund (present value) from age, income, expenses, and savings
  • Combine social pension, employer pension, rental income, and other income sources
  • Output suggested monthly savings, savings progress, and retirement readiness
  • Show total retirement income (nominal/present value), total expenses, and funding gap
  • Support cashflow timing at start or end of month for practical scenario modeling

How To Use

  1. Enter basic profile values: current age, retirement age, life expectancy, income, expenses, and savings.
  2. Enter retirement income sources and retirement income growth rate.
  3. Set inflation, return rates before/after retirement, salary growth, and cashflow timing.
  4. Click Calculate to review target fund, monthly savings suggestion, and detailed metrics.

Calculation Logic

  • Retirement monthly expense compares income replacement and expense projection methods, then uses the higher value.
  • Retirement period is simulated month by month, and net cashflow is discounted by post-retirement return to identify peak funding need.
  • Current savings is projected to retirement date using pre-retirement return, then additional savings requirement is derived.
  • Readiness score is provided for quick planning health checks and parameter review.

Use Cases

  • Build retirement savings plans for personal and household pension preparation
  • Compare different assumptions for retirement age, lifestyle level, and returns
  • Evaluate how income source combinations affect retirement funding gaps
  • Recalibrate long-term retirement budget targets during annual reviews

Notes

  • Results are for planning reference and are not investment or tax advice.
  • Actual retirement needs depend on inflation, market volatility, healthcare costs, and policy changes.
  • Update assumptions regularly and adjust allocation decisions over time.
  • All calculations run locally in your browser without uploading financial data.
