Retirement Planning Guide: How Much You Need and How to Get There

Retirement planning combines a target number, the right account type for your country, and the compounding math that gets you there. This guide organizes every retirement tool on MyCalcKit around those three questions.

How Much You'll Need

• Retirement Calculator — project your retirement savings based on current contributions and growth assumptions.
• How Much Do You Actually Need to Retire? — a framework beyond generic round numbers.
• Savings Goal Calculator and Savings Calculator — work backward from a target date or amount.

Country-Specific Retirement Accounts

• Canada RRSP/TFSA Calculator and RRSP vs. TFSA: Which First? — Canada's two main tax-advantaged accounts.
• Australia Superannuation Calculator and How Much Super Will You Have?.
• 401(k) Contribution Limits for 2026 — US contribution limits, catch-up amounts, and maxing-out strategy.
• 401(k) vs. IRA — which to prioritize, and why using both in sequence often makes sense.

The Mechanics Behind It

• Compound Interest Calculator and How Compound Interest Actually Works — the engine behind long-term growth.
• ISA vs. Savings Account — how UK tax-advantaged accounts compare to regular savings.

Common Mistakes

• Starting the compound interest clock late. Time in the market matters more than timing contributions perfectly — an earlier, smaller contribution often outgrows a later, larger one.
• Ignoring employer matching. Not contributing enough to get a full employer match (where offered) leaves free money on the table.
• Treating all tax-advantaged accounts as interchangeable. RRSP vs TFSA, or 401(k) vs Roth IRA, have different tax treatment that matters based on your current vs. expected future tax bracket.
