# Savings Calculator

Calculate how your savings grow with compound interest. Compare US high-yield savings accounts, UK Cash ISAs, Canadian TFSAs, and Australian high-interest savings. Free.

## Quick Answer

Starting with $10,000 and adding $500/month at 4.8% APY for 10 years, you'd accumulate approximately $89,000 — of which $23,000 is interest earned through compounding.

## Tax-Advantaged Savings Accounts Around the World

The biggest driver of long-term savings returns isn't always the interest rate — it's whether your growth is taxed. Here's how major countries structure their tax-free savings wrappers:

## APY vs AER — Same Thing, Different Names

When comparing savings rates internationally, you may encounter different terminology for the same concept:

## Frequently Asked Questions

More frequent compounding produces slightly higher returns. Daily compounding is marginally better than monthly, which is better than annual. The difference is small — on $10,000 at 5% for 10 years, daily compounding yields ~$64,870 vs. annual compounding's $62,889. The rate difference matters far more than compounding frequency for short-to-medium time horizons.
You can keep an existing Cash ISA if you move abroad, but you cannot make new contributions while non-UK resident. The tax-free status continues for existing balances. Similar restrictions apply to Canadian TFSAs for non-residents (a 1% monthly penalty tax applies to contributions made while non-resident).

## Sources & Methodology

Balance growth uses the compound interest formula with regular contributions: A = P(1 + r/n)^(nt) + PMT × [((1 + r/n)^(nt) − 1) / (r/n)]. Tax treatment and contribution limits for savings wrappers (ISA, TFSA, etc.) differ by country.
