About this calculator
Project investment growth when your annual contribution increases by a fixed percentage every year, compounding along with your returns.
Frequently Asked Questions
Why increase contributions each year instead of keeping them flat?
As salaries rise with raises or promotions, increasing your contribution percentage keeps your savings rate proportional to income and can meaningfully boost long-term balances compared to flat contributions.
When are contributions applied in each year?
This calculator assumes the contribution is added at the start of each year, then investment growth is applied for that year, similar to common retirement calculator conventions.
Does this account for taxes?
No, this is a pre-tax growth projection. Actual after-tax returns will depend on the type of account (e.g., taxable, 401(k), Roth IRA) and applicable tax rules.
