Assessing the Impact of Missed Extra Payments
Each missed month of extra payment means one more month of interest accruing on the higher balance. On a $300,000 mortgage at 7%, each missed $300 extra payment costs approximately $300 × 7% ÷ 12 × remaining months = roughly $1,500 in future interest impact (depending on remaining term). Multiply by months missed for the total impact.
Impact of missed extra payments and recovery approach
| Months Missed | Extra Payment Amount | Approximate Interest Impact | Recovery Approach |
|---|---|---|---|
| 1–3 months | $200/month | $300–$900 in future interest | Resume immediately; apply one lump sum to recover |
| 4–6 months | $200/month | $900–$1,800 in future interest | Restart + apply any windfall (tax refund) to recover |
| 7–12 months | $200/month | $1,800–$3,600 in future interest | Restart + temporarily increase payment for 3–6 months |
| 1–2 years | $200/month | $3,600–$7,200 in future interest | Reassess budget; restart at sustainable level; lump sum helps |
Recovery Strategies
The best recovery from missed extra payments: (1) Resume the extra payment immediately at whatever level your current budget supports. (2) Apply the next tax refund or financial windfall as a lump sum principal payment to recover much of the missed compounding benefit. (3) If income has improved, increase the extra payment above the original amount for 6–12 months to accelerate recovery.
The biggest mistake after missing extra payments: deciding that since you’ve already fallen behind, you might as well not restart. Every extra payment from now contributes to savings. An imperfect restart is infinitely better than no restart.
