About This Calculator

This calculator works backward from a retirement savings target: enter how much you want to have saved by retirement, and it tells you the monthly contribution needed to get there, given your current savings, time horizon, and expected return.

How This Is Calculated

Required Monthly Contribution solves: FV(contributions) = Target − FV(current savings)

To reach $1.5 million in 30 years starting with $60,000 at 7% return, you'd need to contribute about $955/month.

Assumptions

  • Assumes a fixed monthly contribution and constant annual return for the entire period.
  • Does not account for taxes, fees, or inflation eroding the target's real value.

Frequently Asked Questions

A common approach is the 25x or 4% rule: multiply your desired annual retirement spending by 25 (equivalent to planning a 4% annual withdrawal rate) to estimate a target nest egg. Adjust based on your expected retirement length and other income sources.
