Compound Interest with Increasing Contributions Calculator
Most investors plan to increase their contributions over time as income grows. This calculator projects your investment balance year by year, compounding both your investment returns and a yearly percentage increase in contributions.
About this calculator
Project investment growth when your annual contribution increases by a fixed percentage every year, compounding both returns and contribution growth.
Frequently Asked Questions
Why increase contributions each year instead of keeping them flat?
Increasing contributions to match salary growth or inflation can dramatically boost long-term results compared to flat contributions, since more money compounds earlier.
When are contributions applied in this calculation?
This calculator assumes contributions are made at the start of each year, then grows the full balance by the annual return rate for that year.
Does this account for taxes or fees?
No, this is a gross growth projection. For after-tax or after-fee results, reduce your annual return rate accordingly.
