How it works

Compounding reinvests earned yield. Daily compounding at the same APR produces a slightly higher APY than monthly compounding.

Formula

Final = Principal × (1 + APR/n)^(n×years). APY = (1 + APR/n)^n − 1. n = compounds per year.

Examples

8% APR daily for 3 years

$10,000 → APY ≈ 8.33%, final ≈ $12,710, interest ≈ $2,710.

APR vs APY

12% APR compounded monthly ≈ 12.68% APY. Marketing often quotes the higher APY figure.

FAQs

Is staking APY guaranteed?

No. Rates change, validators can slash, and smart-contract risk applies in DeFi. Educational projection only.

What is the difference between APR and APY?

APR is the nominal rate without compounding. APY includes compounding frequency effects.

Can I model weekly contributions?

This version compounds a fixed principal. Combine with the DCA calculator for contribution schedules.
