About this tool

Enter your salary, your contribution and your employer match as a percent of pay, your current balance, years to retirement, expected return and yearly pay raise. The calculator adds contributions each year and compounds the balance to show the total at retirement. Figures are for the 2026 tax year and can change. A guide only, check irs.gov or a tax professional.

How it is calculated

Each year the tool adds your contribution and the employer match, both as a share of that year's pay, and grows the balance by the expected return. Pay rises by the raise rate each year. Contributions are assumed to arrive evenly through the year.

Example

On $80,000, with 8 percent saved and a 4 percent match, a $20,000 start and 7 percent return, the balance after 30 years is above $1.6 million, before inflation.

Limits and tips

The 2026 employee deferral limit is $24,500, with extra catch-up contributions from age 50. Always capture the full employer match first, because it is an immediate return. Results are in future dollars and inflation reduces what they buy.

Consells per obtenir el millor resultat

Comprova cada camp abans de fiar-te d'un resultat, perquè una sola xifra errònia canvia tota la resposta. Fes servir els números exactes d'una nòmina, factura, certificat o contracte i anota la data del càlcul. Els tipus, els llindars i les regles canvien de tant en tant, de manera que per a impostos, taxes i qüestions legals considera el resultat una estimació i contrasta'l amb la font oficial indicada en aquesta pàgina. Pots provar tants escenaris com vulguis; no es desa ni s'envia res i recarregar la pàgina buida els camps.
